Abstract: A BLDC motor drive system may be configured to provide a programmable PWM current waveform, e.g., a sinusoidal PWM current, to the motor. The drive system may include control electronics configured to generate a series of PWM control signals at a control signal frequency based on (a) the present motor speed data as determined by an angular timer, based on sensor-based rotor angle data, (b) a target motor speed, e.g., based on a thermal management unit, and (c) stored current waveform data defining a target current for each angular segment of the BDLC rotor, the target currents defining an non-rectangular waveform shape. The PWM control signals are used by a PWM unit to produce a non-rectangular, e.g., sinusoidal, PWM current for controlling the BDLC.
