MOTOR RADIAN COUNTER LOGIC: CONTROLS THE MOTOR, THE INTERMEDIATE AND THE LOAD CLUTCHES

LOGIQUE SERVANT A COMPTER LES RADIANS D'UN MOTEUR : COMMANDE LE MOTEUR ET LES EMBRAYAGES INTERMEDIAIRES ET DE CHARGE

English Abstract

This invention operates in some ways very similar to a Stepper Motor. The main
difference is
that the Final Step or Load Position is reached directly in one continuous
motion without
employing evenly spaced Rotor Sequencing Steps. The invention also offers the
option to
select any Non-Stepper Motor which has the best operating characteristics for
the required
design. Motor Characteristics may be as follows: Starting or Running Torque,
Speed, Power,
Wattage, Duty Cycle, Breaking, Cooling, Size, Current, Voltage, Maintenance
and Cost.
The Load can be disconnected from the Rotor Shaft by an Intermediate Clutch.
The Load has
less Inertia because the Motor is disconnected by the Intermediate Clutch.
This invention
runs cooler and more efficiently because the Load can be held by a Residual
Field Magnet
without using continuous holding Power. The Motor can be continuously running
because the
Intermediate Clutch is a rotating holding magnetic link between the Motor and
the Load.
An Optical Sensor Counter counts the rotating Number of Reflectors on the Load
Disk or the
Light Beams which pass through Slots on a Load Cutch Disk or on a Motor Disk.
The Count
Number represents the Terminal Angle or Final Load Position and this number is
fed to a
Controller. The Controller in turn controls through Binary Logic three Electro-
Magnetic
Clutches. One Motor Clutch controls whether the Motor must be stopped or
continue to
rotate. A second, Intermediate Clutch, links the Motor Rotation to the Load
and permits the
Load to rotate at the same Speed as the Motor. The energized Load Clutch
prevents the Load
from rotating when the Intermediate Clutch links the rotating Motor and the
Load. The Load
Clutch must prevent the Load Output from rotating if the Intermediate Clutch
is disengaged.
The Motor Clutch is employed to stop the Motor from rotating through damping
or more
forcefully depending on the Speed of the Motor, the Running Torque and the
Angle or
Radian Count. This invention isolated the Motor and the Load Characteristics
from each
other so that the designer has more opportunities by employing more advantages
and to in
many situations to run the Motor more efficiently when the Load is disengaged
eg. breaking.

Claims

1
The Embodiments of the Invention in Which an Exclusive Property or Privilege
Is
Claimed Are Defined As Follows:
1. This invention is designed to operate as a Stepper Motor but bypasses all
the
Intermediate Steps before the desired position is reached, Fig 6.
2. This invention does not depend on the conventional Number of Teeth nor the
Frequency of Pulses from a Controller because it uses an Angular or a
Radial Counter Controller to locate the Initial and the Final Position of the
Load and or the Position of the Motor. Fig 1 and Fig 6.
3. The invention Controller Logic can be programmed to operate any of the
three Clutches under any combination of production requirements and to
gain access to analyze all the possible advantages of any Motor, Fig 6.
4. The initial, running, downtime, maintenance costs are very low because a
simpler Controller is employed and higher production speeds can become
available.
5. The invention is designed so that under many circumstances which may
occur during the starting, running or after a process is completed, the Motor
and the Load Characteristics can be isolated from each other to provide
many operating advantages.
6. This invention is designed so that the advantageous characteristics of non-
Stepper Motors can be selected and employed.
7. The invention focuses on bypassing the disadvantages of the heat losses,
the
limitations of Torque verses Motor Speed of the Stepper Motor designs
because the Motor can stopped independently from the load or continue to
run independently from the Load under certain Load Conditions. Fig 4 &
Fig 5.
8. The Motor is stopped independently from the Load so that the Motor Inertia
is not factored when the Load Inertia is being analyzed. Fig 4, 5, 6.

2
9. The efficiency of the invention is much more because the motor is operating
cooler with less heat losses due to the fact that the Load does not have to be
held from rotating by constant power.
10.The entire production of a process can be made much faster because it does
not require any delays to obtain a Stepper Motor with the correct Number of
Teeth.
11. The Motor can run much faster because the effects of high Frequency verses
Torque or Speed or Maximum Wattage or Max Current.
12.The invention can operate at much higher Wattages by using other types of
AC or DC Motors so that more machining and transportation application
become available.
13. Overall higher efficiency and isolation of the Motor from the Load make
the
system much safer to operate even in highly combustible environments.
14. The work environment can be much cooler and quieter for humans and for
agricultural animal environments.
15. The conventional Stepper Motor concerns about Load Inertia are
downgraded because under many circumstances' the Motor can be stopped
or continue to operate because the two can be operating independently from
one another.

1 Title of this Invention is:
2 Motor Radian Counter Logic: Controls the Motor, the Intermediate and the
Load
3 Clutches.
4 This invention can employ a functioning Stepper Motor or other types of
Electrical Motors.
All Intermediate Steps can be bypassed until the Final Terminal Step or Final
Position Step
6 through the use of a Radial Sensor Counter, Controller Logic Circuits and
three Electro-
7 Magnet Controlled Clutches, Fig 1. Side View: Optical Led Source and Counter-
8 Controller. Each of the three Fields is spatially and magnetically isolated
by non metal
9 support disks and shafts and where possible by magnetic shielding. The count
can be reset
at any position so that larger radial distant positions can be set without
Intermediate Steps.
11 A Motor Radial Load Position Disk, an Optical Led, and an Optical Sensor
Counter are
12 used to generate a Signal which feeds a Logic Controller. The Controller
Output
13 simultaneously controls the following three Electro-Magnet Controlled
Clutches: 1. A
14 Torque Primary Motor Stopping Clutch. 2. A Torque Intermediate Motor Clutch
and 3. A
Torque Holding Load Clutch. The Field Strength of each of these Clutches can
be either
16 energized as a Temporarily Holding Field Magnet or it can retain its Field
Strength as a
17 Residual Holding Field Magnet. Fig 1, 3, 4, 5, 6.
18 The Work Design, the Energy Efficiency / Coil Heating, the Motor and Load
Motion Safety
19 Requirements and the Work Termination determine whether any of the three
Holding
Clutches is an Energized Electro-Magnetic Temporary Field Magnet or it is a
Residual
21 Field Magnet.
22 These three Electro-Magnet Controlled Clutches operate simultaneously but
independent
23 of each other. The Torque Holding Load Clutch has the greatest Field
Strength Value and
24 must not permit the Load Clutch and the Load to rotate unless the
Controller signals them
to rotate. The Load Clutch must support precisely the Position of the Load
under the
26 following conditions: 1. while the Position must be maintained for some
work process
27 regardless of the rated Load 2. while the Torque Intermediate Motor Clutch
is being
28 disconnected ie demagnetized because residual magnetism may cause the Load
to rotate, 3.

1 while the Torque Motor Stopping Clutch is becoming engaged to stop the Motor
from
2 rotating. 4. while the Load is still under a work process 6. while an
emergency stop exists.
3 Note:
4 Under certain production circumstances and the nature of the production may
require the
complete stopping of the Motor or the Motor may continue running while the
Torque
6 Intermediate Motor Disk is disconnected from the Torque Intermediate Clutch.
This can
7 be the case where the Motor Speed is slow and the Load is great or when the
speed is slow
8 but there are many close steps. This Motor runs cooler and more efficiently.
Fig 4. and 5.
9 The Torque Intermediate Motor Clutch is required to be strong enough to
permit the Load
to rotate at the same speed as the moving Motor and without Load Slippage, Fig
4 and 5.
11 A Load is isolated from the Motor Rotation and without employing the Normal
12 Sequencing Steps of a Stepping Motor which limits the Speed and lowered the
Motor
13 Efficiency because the Magnetic Coils were continuously energized producing
Heat Losses.
14
The Torque Primary Motor Stopping Clutch Disk is attached to the Motor Shaft
and can
16 rotate at the same speed of the Motor. The Torque Primary Motor Stopping
Clutches are
17 in fixed positions on a separate Stopping Motor Clutch Shaft but when
electrically
18 energized the Stopping Clutch will slide to the left to provide motor
damping, breaking or
19 stopping.
The Motor Shaft has an attached Intermediate Motor Clutch Disk which rotates
when the
21 Motor is powered and free to rotate and all breaking Clutches are
disengaged eg the Motor
22 Clutch and the Load are not braked. To the right of the Motor shaft are two
more types of
23 separately supported non metallic shafts. The second or middle shaft is a
single separately
24 supported non-metallic Torque Intermediate Motor-Clutch Load Shaft. This
shaft
supports a sliding electro-magnet Torque Intermediate Motor Clutch and a fixed
attached
26 Load Holding Clutch Disk.

1 The third shaft system uses two shafts used to magnetically brake or to hold
the Load
2 during a production process step or to lock the Load. Two shafts are used to
ensure cooling
3 , efficiency and safety as a single Clutch brake could fail and cause an
accident. Fig 5.
4 The Torque Intermediate Motor Clutch is an electro-magnet Disk or Ring that
is powered
by a set of two conductive Electrical Slip Rings and Brushes. Here one
Clutchor two
6 clutches can be used but one is easier to align the Clutch Disk and the
Single electro-
7 magnetic Clutch. Electricity energizes the Torque Intermediate Motor Clutch
which causes
8 it to slide to the left and become magnetically coupled with the Torque
Intermediate Motor
9 Disk. When the Motor is also energized and the Motor is free to rotate, then
the non-
metallic Torque Intermediate Motor-Clutch Load Shaft can rotate at the same
speed as the
11 Motor if the Torque Intermediate Motor Disk is not braked. It is attached
to the left side of
12 the non-metallic Intermediate Clutch-Load Disk Shaft. It is attached to but
can slide to the
13 left or to the right along a non metallic Intermediate Clutch-Load Disk
Shaft.
14 When the Torque Intermediate Motor Clutch is electrically energized it can
slide to the left
to magnetically attach to the rotating Intermediate Motor Clutch Disk.
16 Note a Review: There is a separately supported non-metallic Intermediate
Clutch-Load
17 Disk Shaft which supports on the left end, the left to right sliding
electro-magnetic Torque
18 Intermediate Motor Clutch and on the right end is the fixed attached Load
Holding Clutch
19 Disk. The Intermediate Clutch-Load Disk Shaft can rotate when powered by a
moving
Motor or by a moving Load is when no brakes are applied. Note: When the Motor
is
21 disconnected a Load can have sufficient inertia and can also rotate if the
Load Clutch is not
22 employed by failure or by an error from the Controller. The overall system
offers more
23 safety because the Motor can be disconnected from the Load by a emergency
switch.
24 Two Load Holding Clutch Shafts are separately supported to the right of the
Load Holding
Clutch Disk. Each of these Load Holding Clutch Shafts holds a sliding electro-
magnetic
26 Load Holding Clutch. The Load Holding Clutch Disk is a part of the Load
Gear or the
27 Load Pulley Assembly. When the electro-magnetic Load Holding Clutch is
energized it
28 slides to the left to engage against the Load Holding Clutch Disk so it can
provide damping,

1 breaking or stopping to the Load Holding Clutch Disk and the final Load. The
electro-
2 magnetic Load Holding Clutch is powered by a set of two conductive
Electrical Slip Rings
3 and Brushes. Energize clutch then slides to the left.
4 The Load Holding Clutch Disk is attached to right end of the non metallic
Intermediate
Clutch-Load Disk Shaft. It does not slide on the Intermediate Clutch-Load Disk
Shaft.
6 The Load will rotate when the following conditions are met: 1. The Motor is
energized and
7 rotates without the electro-magnetic Torque Primary Motor Clutch causing
damping or
8 breaking on the Torque Primary Motor Clutch Disk. 2. The Torque Intermediate
Motor
9 Clutch Disk is magnetically attached to the Torque Intermediate Motor
Clutch. 3. The
Load Holding Clutch Disk is not damped nor braked by the electro-magnetic Load
11 Holding Clutch. Fig I to Fig 6.
12 Note that Fig 6 is a complete drawing of the invention. Note well which
parts are fixed in
13 position and which can slide left and right or which can slide and rotate.
14 For example a Clutch which operates as a brake must not rotate but slides
against a
moving Disk to dampen, to brake or to hold it for a long time or to stop it
from rotating at
16 the end of a production process.
17 For example a Clutch which operates as a rotating Clutch to synchronize the
movements of
18 the Motor to the Load must rotate and slide against its counterpart
rotating Disk, see Fig 4
19 and Fig 5.
Refer to the drawing text boxes which mentions if the part rotates and or
slides on a Shaft.
