Permanent Magnet synchronous motor and Brushless DC motors are replacing DC brush motors more and more in many applications due to advantages such as higher efficiency, quieter operation and better reliability.Despite their d ifferent structures, all three-phase permanent magnet motors (BLDC, PMSM or PMAC) are driven by a pulse-width-modulated (PWM) three-phase bridge (thre e half bridges) in order to supply the motor with variable frequency and am plitude of voltages and currents.To provide the highest level of design fle xibility, ST?s product portfolio includes specific products for bot h high- and low-voltage applications like monolithic drivers ICs, power MOS FETs, IGBTs, gate drivers, power modules and dedicated microcontrollers to address a broad range of applications.
