Motor Control Solutions

STMicroelectronics Motor Control Solutions are a portfolio of products for low-voltage motor control applications. These products include monolithic driver ICs, power MOSFETs, IGBTs, gate drivers, power modules, and dedicated microcontrollers to address a broad range of applications. STMicroelectronics has boards and reference designs for Low Voltage Motors, which include < 100V all the way to High Voltage Motors 600V up to 1200V. Permanent Magnet synchronous motors and Brushless DC motors are replacing DC brush motors in more applications for advantages like higher efficiency, quieter operation, and better reliability. Despite the different structures, all three-phase permanent magnet motors (BLDC, PMSM) are driven by a pulse-width-modulated (PWM) three-phase bridge (three half-bridges) to supply the motor with variable frequency and amplitude of voltages and currents.
