Anyone care to help me with wiring on my 3 phase Baldor Motor?

I've got a KBMA variable frequency drive and a 1 HP Baldor washdown motor (230 VAC, 3 phase). I've already finished wiring the line input to the drive and the line output from the drive to the motor. As usual, there are three lines between the drive and the motor. I have no questions regarding this part of the wiring.

My problem is that the Baldor motor has 9 wires, and I cannot discern which ones should be jumped together. I have the drive lines L1, L2, L3 connected to their appropriate lines (T1, T2, T3) on the motor. When I received the motor the lines T6 and T9 were jumped together but I disconnected these since think this is only for low/high voltage applications. The Baldor manual for this motor has multiple wiring diagrams. I feel that I've followed the diagrams well, but the motor won't turn. I think I need to jump more of the 9 motor wires together.

If anyone is skilled in this matter, I'd happily call or PM with you about how to get this hooked up properly.

BTW, this is for my new disk grinder.

We need more info

Post a good photo of the data plate and all the wiring diagrams


we may as well do it right here

If that three phase motor has a diagram for 220v and 440v, then you are picking between the diagrams to choose the low voltage diagram.





Are you hooking up 110 or 220 input to the controller
and do you have those jumper correct ?

Guys, I got it. The hint about using low voltage helped. It also helped when I discovered the wiring diagram inside of the junction box cover plate. That helped me discover that it uses a wye connection rather than a delta.

I've posted the photo and wiring diagram from the Baldor manual anyway.

Thanks.
