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.

摘要： Electronic circuits for controlling the speed of a motor include a receiving node coupled to receive a speed command signal representative of a desired final speed of the motor. A speed control circuit applies a selected amount of power to a motor to allow a speed of the motor to approach a predetermined final speed, where the selected amount of power provided is based on the desired final speed of the motor. A signal represents the speed of the motor and a feedback circuit uses the signal to regulate the speed of the motor by phase-locking the speed of the motor to the speed command signal once the speed of the motor falls within a predetermined threshold of the final speed. Methods for controlling the speed of a motor are also disclosed.
