He uses a L6234 Three Phase Motor Driver, but points out that there are other ways to interface the BLDC motor with the Arduino. A warning is warranted – this is not for the faint of heart.

Generally speaking, three-phase motors are less troublesome than single-phase motors, having no starting relays or capacitors to deal with. All three-phase units are high-starting-torque motors and ...

For example, to plan for a 3% voltage unbalance with a 100-hp 3-phase motor, the de-rating factor of 88% is used. This calculates to only allowing the motor to do the work of 88 hp. The motor size ...
