This is a a 2 speed Nuva Ibmei HV 21 induction motor from a washing machine I will be using for a tumbler project. Alas there is no wiring diagram on the casing so I need to reverse engineer the schematic.
Its a 2-speed 240v AC reversible motor with five wires to the plug as as viewed from above (left to right and top to bottom);
1.black stripe, 2.blue, 3.yellow,
4.no wire, 5.red and 6.brown.
There is no earth wire on the motor so the unit needs to be earthed from the mains supply.
Resistance between terminals is as follows;
Testing the wires on a motor in a host machine indicates;
1. always has 240v from neutral
2. and 5. are switched via the controller for fast speed
3. and 6. are switched via the controller for slow speed and as said before connected to the startup capacitor
2. and 3. where connected to the control unit are insulated whereas 5. and 6. are bare
Given there is no wiring diagram on the casing or inside the washing machine reverse engineering the schematic is the go. Why would there be a pair of wires for each mode if nuetral is always supplied to terminal 1?
PS we run 240V household wiring in Australia.
