Turntable motor winding resistance is typically 10-20kΩ, somewhat earlier than the resistance of the product is less than 10kΩ, usually 4 ~ 8kΩ. Cooling the motor winding resistance of 100-250Ω. Turntable motor and the motor winding faults are mostly cooling sealing off the ends or broken wire mold , usually not difficult to detect and repair , if it is open or shorted windings inside , you need to re- wound winding disassemble or replace the motor.3eUservice manual download site

    Turntable motor winding resistance of different models with the product and the difference may be larger, if it is difficult to judge based on the measured resistance , you can power test , as long as the gear set and the rotor is not jammed , usually the motor will rotate ; If the speed is normal and Turn the motor housing 5 minutes without burning, generally no problem . If the motor does not turn , indicating a problem with the gear or rotor , a few may be winding poor contact , which would overhaul the motor must be disassembled . Speed ​​is not normal or turn on a hot motor will also be open maintenance, repair is difficult to consider renewal parts . Similarly shaped turntable motors available , similar characteristics 3 ~ 5W Box Fan synchronous motor substitution, usually used to good effect.3eUservice manual download site
