Abstract
There are disclosed herein various implementations of a method and a system enabling operation of a motor in reverse. Such a method includes applying a first drive signal to begin rotating the motor in a reverse direction, the first drive signal being applied for a predetermined period of time. The method also includes using a position sensor signal for the motor to control motor drive in the reverse direction when the motor reaches a predetermined reverse speed, and operating the motor in the reverse direction.
Claims18
A method enabling operation of a motor, said method comprising:
- applying a first drive signal to begin rotating said motor in a reverse direction, said first drive signal being applied for a predetermined period of time;
- using a position sensor signal for said motor to control motor drive in said reverse direction when said motor reaches a predetermined reverse speed;
- operating said motor in said reverse direction.
A system enabling operation of a motor, said system comprising:
- a motor configured to operate in a forward direction opposite a reverse direction;
- a motor controller coupled to said motor, said motor controller configured to:
- apply a first drive signal to begin rotating said motor in said reverse direction, said first drive signal being applied for a predetermined period of time;
- use a position sensor signal for said motor to control motor drive in said reverse direction when said motor reaches a predetermined reverse speed, thereby operating said motor in said reverse direction.
