Brushless DC (BLDC) motor drives electronically commutate motor phases with precise timing to deliver efficient, high torque density performance without the wear of brushed contacts. They depend on fast, efficient switching and accurate phase-current feedback.
Vishay's isolated IGBT / MOSFET motor drivers, power MOSFETs, and modules switch motor phases efficiently, while non-contacting position sensors provide the rotor position feedback electronic commutation depends on. Our shunt resistors deliver the phase-current feedback needed for precise torque control, ceramic capacitors and inductors filter drive power rails, and TVS diodes protect against motor-generated voltage spikes.
