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.

The basic function of a variable speed drive (VSD) is to control the flow of energy from the mains to the process. Variable speed drives sit between the electrical supply and the motor. Power from the electrical supply goes into a drive and the drive then regulates the power that is fed to the motor. Inside the drive the input power is run ...

The speed of a DC motor (N) is equal to: Therefore speed of the 3 types of DC motors shunt, series and compound can be controlled by changing the quantities on the righthand side of the equation above. Hence the speed can be varied by changing: The terminal voltage of the armature, V. The external resistance in armature circuit, R a.

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.

The cable that powers the VFD is a 12/3 SOOW SO cord and a 14/4 SOOW SO connects the VFD to the motor. To connect the VFD to the remote control, I used an 8conductor 24gauge Ethernet computer cable, run inside a piece of 3/8" flexible conduit for protection. (You only need six of the conductors for the remote.)

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 ...

Automotive. Feb. 11, 2021. The speed of a DC motor can be controlled by adjusting the voltage applied. This is because the speed and load torque of a DC motor is inversely proportional, and this translates with changes in drive voltage. Linear or PWM control can be used to vary the motor drive voltage, but PWM control has come to predominate in ...
