Figure 6 Basic block diagram of supporting power management devices for motor control. Source: Microchip AC-DC converters utilizing SiC in tandem with gate drivers enable precision switching for ...

Technically speaking, the motor control must be based on torque and magnetic ... which requires one important input—the rotor position. We see in the diagram that this value is fed to the ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO block in a phase-locked loop ... due to dc resistance in the motor (see diagram).
