Winding data for AEI BK-2410-C B56 motor?

(1/2) > >>

CambridgeMart:
My lathe suddenly started tripping the breaker and I discovered that there was a low resistance to earth from the windings. I've tried to price a replacement motor, but it's difficult to find a direct replacement due to the mounting arrangements. I had a couple of quotes for rewinding the motor and it was more than I paid for the lathe!

I decided I'm going to rewind the motor myself, but working out how all the windings are interconnected is a nightmare; I know I could probably get the data from the EASA database, but membership of EASA is hugely expensive. Hoping someone may be able to help.
The motor is an AEI BK-2410-C B56, it's 4 pole 3 phase 415/230V 1hp / 0.75kW, the stator has 36 slots.

Wow... it really can be hard for the non-experienced, although it is really mostly a mechanical grasping!
I used to rewind tons of motors, as I had no choice when working in the bush many years ago!! ...
If it is 4 pole, and has a total of 36 slots, then that's 9 slots per pole. So you 'should' find that each 'pole' would
have so many turns looping around say slots 1 to 9, which then connect with the same wire to so many turns
looping around slots 2 to 8, and so forth for slots 3 to 7, 4 to 6,  for example.  These groups of coils are made
typically on a layered wooden rectangular plywood 'former'...

You then knock out the wooden/plastic bits covering each slots coils, and keep them for re-use.
Chop the windings off at one end, and count the turns, and knock the windings out of the slot tunnels.
When the new windings are loose & unvarnished, you can 'jiggle' them into the slots/cavities, before using an
insulating material like 'ElephantHide' to slide on top, before knocking in the top 'wooden' saved pieces.
Later, varnishing will hold all the coils together properly, so there is no magnetic vibration.  Connect the coil
ends as per the observations during dis-assembly.  I don't know what more to say!!
It's do-able, but not for the feint hearted...  Good luck !   :(

Go to archive.org and read some old books on motor winding. They should be very educational for you.

G7PSK:
I used to take motors and alternators to a local rewinder, if they did not have the details in a reference chart they just cut the ends of the windings and counted the end of the wires to get the number of turns.

alpher:
Rewinding 1Hp motor  ::), it will cost certainly more than a new one.
Such a small motor is a major pain to rewind and will probably cost more than bigger ones.
What so spacial about it? isn't it a standard 56 frame ?
