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.

3-phase 6-STEP Control
In a 6-step, or scalar control, normally only the frequency and magnitude of the voltage fed to the motor are controlled while current feedback is not mandatory.
View application 3-phase Field Oriented Control (FOC)
Field-oriented control (FOC), or vector control, is a technique for variable frequency control of the stator in a three phase AC induction motor drive using two orthogonal components. One defines the magnetic flux generated by the stator, while the o
View application Single Phase Brushless Motor
Single-phase brushless motors are driven through a full H-bridge with PWM control, where the direction of the current is defined based on the feedback from a Hall effect sensor. ST offers monolithic power stages, embedded gate drivers, power transist
