  • Publication number: 20250112575
    Abstract: According to some embodiments, a motor controller for controlling a motor includes a position interface configured to receive a motor position signal indicative of a position of the motor, and a pulse width modulation (PWM) unit configured to generate a PWM signal for driving the motor. An angle and speed unit is configured to determine a speed and a position of the motor based on transitions in the motor position signal, wherein transition intervals are defined between the transitions, determine a PWM count of cycles in the PWM signal during a first transition interval of the transition intervals, and update the position of the motor during a second transition interval of the transition intervals based on the PWM count to generate an updated position. A controller is configured to send a control signal for controlling the motor to the PWM unit based on the speed and the updated position.
