SPINDLE SPEED This wheel is used to change the speed of the spindle for both high range and low range. The milling machine must be running when changing the speed. POWER FEED The power feed uses a motor to control the motion of the longitudinal feed in either direction at various speeds. Not all of the milling machines in the shop have this option.

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 ...

The speed can be regulated to some extent but not above the normal level of speed. Shunted Armature DC Motor Speed Control Method Armature Terminal Voltage. The speed of a DC series motor can also be done through power supply to the motor using an individual varied supply voltage, but this approach is costly and not extensively implemented.

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.
