1. CONTROL OF THE COLLECTOR ELECTRIC MOTORS ON WM WITH EL.
REGULATION
When rotor of the electric motor comes into short circuit it is likely that the el.
regulation will get damaged. It is impossible to check short circuit with the multimeter
at the customer due to very low impedance.
To avoid new el. regulation to get damaged is our suggestion to check el. motor as
follows:
Check visual electronic regulation (burnt out components).
Check wiring harness
Connect new el. motor
If it does not rotate and wiring harness is O.K. , change el. regulation.
Before connecting old el. motor, check it as follows:
Visual: burnt out collector, damaged collector – change the el. motor
Adjust wash program to the intermediate spins or final spin on washing machine with
800 – 1000 rpm (with potentiometer or with switch reduce the spin to the minimum).
Intermediate spins perform in steps , it is low possibility of getting el. regulation
damaged due to short circuit of the el. motor rotor coil.
If the rotor coil is in short circuit, there will be sparkling on the collector. If there is no
sparkling, wait for the end of the spin and try again.
