SYSTEMS AND METHODS FOR REDUCTION OF MOTOR JITTER WHILE DRIVING AN ELECTRIC MOTOR |
摘要 |
An apparatus for driving a motor comprises a drive signal generation circuit configured to produce pulses on a pulse-width modulated drive signal in response to a control signal. A detection circuit is coupled to receive a commutation signal from the motor to monitor the speed of the motor. A control signal generation circuit is configured to dynamically generate the control signal so that a frequency of pulse-width modulated drive signal corresponds with the duration of the phase of the motor, so as to reduce the occurrence of an incomplete pulse on the drive signal. Methods for driving a motor are also disclosed. |
