reversible pole receptacle

[BuffaloJohn]

I thought I would look for the motor (a replacement part) online, not much to see, but I did find a controller for a Matrix T7xi and here is the label on it:



So - that motor controller output is for a three phase AC motor and likely is a VFD. Check the controller of the treadmill you are getting and you may find the info you need...

The Life Fitness CLST motor or motor controller is hard to get an image of, but there are a number of listings of that company's motors and they list as DC motors. The motor has a nameplate, but the images are just too small to read anything online.

I found AC and DC motors. I'll wait until I have them in hand. The current may influence my choice. I am restricted to a 120v receptacle for my experiment.

The motor model # is JM11-007. It is for a Matrix brand treadmill. It's AC 60Hz 3ph and 1500w (230v X 6.5A) thus 2hp. I'll have 2 motors and 3 treadmill decks. I intend to power the 2 outer decks and to cover all 3 with a single conveyor belt to assure a smooth surface for lateral transition/footwork and to make sure the decks turn synchronously.
I have the controls from one of the treadmills, which includes speed control. My thought is to gang the 2 motors through a single gang receptacle (connect with a 2 receptacle pigtail?) with the one speed control wired upstream from the receptacle and still within the gang box. I also want to reverse the motor direction, which I'd like to do within the gang box.
I am grateful for all replies.

The tread mill(s) would have a variable frequency drive built in I would think. That would be a nice setup for a powerful wood lathe or a swap out for a metal lathe. I know that's not what you want.

No, but I kinda like the idea.

These motors have their speed controlled by voltage not frequency, most are DC anyway needing a frequency of zero.

He has three phase motors from the treadmills - thus they are controlled by frequency using a VFD - variable frequency drive.

Three phase motors are induction motors. While there is a voltage component of the VFD, the primary control of speed is the frequency of the AC 3 phase waveform (there is a voltage component in VFDs which is used to keep the motor from overheating by keeping the magnetic flux within the design parameters).

Yes there are many treadmills that as DC motors, but not these...

I stand corrected. Thank you.
