Abstract:
Techniques are disclosed for facilitating control of electric motors. A system includes a brushless direct current (BLDC) electric motor that includes a rotor and windings, where the rotor is configured to rotate with an adjustable angular speed. The system further includes a plurality of switching regulators. Each switching regulator is configured to generate an electrical drive signal based on to a torque control signal, where the angular speed of the rotor is based on the electrical drive signals. The system further includes a commutation logic circuit configured to selectively provide the electrical drive signals of the switching regulators to the windings based on a position of the rotor. To selectively provide the electrical drive signals, the commutation logic circuit may be configured to provide routing control signals provided as six-step commutation signals or motor phase control signals provided as sinusoidal commutation signals. Related systems, devices, and methods are also disclosed.
