b. Check
Main winding/power-supply winding/DC winding
If there is not DC voltage output, check if the DC
over-current protector trips and the DC receptacle are
damaged. If yes, replace the receptacle.
If there is no AC voltage output, check if the AC
receptacle is damaged. If yes, replace the receptacle.
Check if there is voltage between the motor stator and
power-supply winding. If yes, replace the converter.
Otherwise replace the stator.
The resistance among windings of 230 V 2 KW is as
follows:
The resistance among windings of 120 V 2 KW is
as follows:
The resistance among windings of 100V 2KW is as
follows:
Replace the stator if the resistance is zero or infinite.
Disassemble the stator from motor.
Check if there is obvious damage on the varnished
wire of each winding and the insulating layer of guide line.
If yes, replace the stator.
Note: be careful not to damage the varnished wire of
each winding and the insulating layer of guide line when
disassembling and assembling stator.
