High efficiency treadmill motor control

摘要

A high voltage direct current signal is obtained from a power supply. The power supply includes power factor correction circuitry. A control command is obtained from an exercise machine. The exercise machine includes a direct current motor. A pulse-width modulation signal is generated from the direct current signal based on the control command. The pulse-width modulation signal is provided to the direct current motor.

主权项

1. A method to provide high efficiency direct current motor control, comprising:
obtaining, by a direct current motor controller, a high voltage direct current signal from a power supply having power factor correction circuitry; obtaining, by a processor, a control command from an exercise machine having a direct current motor; generating, by the processor, a pulse-width modulation signal from the direct current signal based on the control command; and providing, by the direct current motor controller, the pulse-width modulation signal to the direct current motor.
