  • Contactless power supply and motor control system
    Patent number: 11522477
    Abstract: A contactless power supply and motor control system includes a pulse width modulator, a rotary transformer, a demodulator circuit, a motor driver, and a motor. The pulse width modulator supplies a first pulse width modulated (PWM) signal that has a duty cycle and a first amplitude. The rotary transformer receives the PWM signal. The secondary winding is rotatable relative to the primary winding and supplies a second PWM signal having the duty cycle and a second amplitude. The demodulator circuit is rotatable with the secondary winding and supplies a demodulated direct current (DC) voltage having a DC voltage amplitude. The motor driver is rotatable with the secondary winding and the demodulator circuit and controllably supplies motor current. The motor receives the motor current and rotates at a rotational speed.
