I'm thinking about using a Parker brand frameless kit motor to power a mill spindle. I'm particularly drawn to the direct drive ability and low profile. They are BLDC motors.

Is there a way to power and control these motors without a servo amp, but rather a simple and less expensive speed control? I'm not yet familiar with BLDC motors.

These are the motors.

Some of them are supplied with an integrated commutation assembly.

Any help would be appreciated.
