Fisher & Paykel 3 Phase Motor Drive

Guest
Hi,

I recovered an old power module with motor out of a Fishher & Paykel
Washing Machine.

My interest would be to run the motor with speed and direction control
in other applications.

The motor is open frame, electronically commutated with 11 wires
including earth. It looks very cheap.

The power module is a long unit at the botom of the machine.
Dates printed on the circuit board and components are 1985/86.
It has a transformer, an EMI filter board, and a mother board that
contains a rectifier, 2 24V relays, a power supply doughter board, 3
inverter daughter boards, a CPU board and 2 other daughter boards,
possibly one is I/O to the inverters and pump circuit, the other may
be an interface board to the timer which I don't have.

The interesting part is that the unit appears to be controlled
exclusively by 3 wires, labelled:
CMD
+5V ISOL
ECHO

That looks like a serial connection.

Are there any chances to get this going?

Many thanks,

Bernard

I have a but to do with F&P machines and the unit you have describes
sounds nothing like what I have seen, perhaps its an earlier model.
Cand you provide a model number?

All the ones I have seen have a controller board and display board in
the top of the unit. The only PCB in the bottom of the machine is a
motor position sensor.

Thats how mine is too. brains at the top.
Motor and RPS at the bottom.

Oops forgot to add the model # MW053. 1996......

The RPS and the motor have been replaced already. Hope the computer aint
next!

Thanks for your replies.

This is out of a very old model, with a belt drive. I have been told
that it was probably the ECS series.

It definitely has the power controller in the bottom, a large box
extending from the front to the rear. What the top looked like I don't
know.

hi Bernard..

What you have there is a Gentle Annie ECS Washmachine Drive..
I have the same model which is set out as you describe..
The Variable speed Drive is located at the base of the machine, which is
located near an open exposed Motor.

I'm not sure how you would hash this drive to run without the Controller
module from up top of the machine..
Id be interested to know myself, as these Drives are quite readily available
at recycler centres..


Cheers

Ren
