Advantage: heating speed is quick.Disadvantage: need different induction coils for different motors as each motor / stator may have different wire heads for soldering, complex for changing induction coils.Equipment: UM-20AB-UHF

Advantage: one induction coil can be used for heating different wire heads of motor / stator, easy for operation.Disadvantage: heating speed is not quick enough, may need bigger power of induction heater.Equipment: UM-30AB-UHF or UM-20AB-UHF
