In the United States this frequency is fixed at 60 Hz (most other countries use 50 Hz), which results in a rotations per minute (RPM) of 1800 (for a motor with 4poles). This speed is too fast for rigid tapping, which occurs around 300500 RPM, and is too slow for efficiently cutting aluminum. A Variable Frequency Drive or VFD is a device that ...

Therefore in order to control the speed of a standard AC motor, the applied frequency and voltage must be controlled. Although it is difficult to control voltage and frequencies at these high powers, the use of a standard induction motor allows a cost effective speed control system to be built. The Variable Frequency Inverter.

Sep 10, 2015 #2 Dc can be used, but your suggested motor is not a good choice. A legitimate industrial motor will have compatible rpm. If the motor is 3 phase, a good choice is a VFD, which will give variable speed, and use what you have. The treadmill motors have low torque, and make up the power with high speed, often 4000rpm, or higher.
