Best of all, the entire package will only run you about $20 in parts–including the position sensor! “Another BLDC motor controller?” you might think. “Surely, I’ve seen this before “.

Setup 4-wire 2-phase BLDC motor speed control (2000 to 7600 RPM), two motors are to be controlled independently The tools used are Code warrior 10.x and Graphical Configuration Tool etc provided with ...

This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special mechanical switch to select the operating mode.

Power Integrations’ Motor-Expert™ Suite for BridgeSwitch™ IC family includes new control software for three-phase BLDC motor drives. Image provided courtesy of Power Integrations.

Now, special gate-drive circuits are available to mitigate these problems. Gate Drivers: The Key to Superior BLDC Motor Control Different MOSFETs have widely differing gate-drive requirements.
