Despite their different structures, all 3-phase permanent magnet motors (BLDC, PMSM or PMAC) are driven by a PWM-modulated three-phase bridge (three half bridges) so as to supply the motor with variable frequency and amplitude three-phase voltages and currents.

To provide the highest level of design flexibility, ST’s product portfolio includes specific products for both high and low-voltage applications like monolithic drivers ICs, power MOSFETs, IGBTs, gate drivers, power modules and dedicated microcontrollers to address a broad range of motor control applications.
