VFD for Hardinge DSM-59

[Ronno6]

I have a Doerr 3N229D 5hp 230/460V 3ph motor.
It has no capacitors mounted on it.
It does not say "Induction" on it......how do I tell if it is or not?

3 phase uses no capacitors. It is self-starting.

Almost certainly induction, that is still the most common type. Got a pic of the tag?

You should start a new thread for this sort of question. Please do.

Will post a pic later.
i should have put the post in context: I want to use it as an idler motor for an RPC.....

thanks car2 & JST i an not up on the ins and outs of the VFDs and did not know that.
that explains the need for the RPC.

Will the direction of rotation of the idler motor indicate the direction of rotation of the spindle motor?


inside the control box, incoming line 1L1 connects to H1 on the control transformer, and it is jumpered to H3. Lead 1L3 is connected to H4 on the transformer, which is jumpered to H2.
That leaves 1L2 as the only line-in lead not connected to the transformer. That will be the lead that id connected to T3, the manufactured lead from the RPC ?
