PROBLEM TO BE SOLVED: To prevent breakage of a motor shaft and wear of a clutch brake by reducing inertia force caused by a motor and a spiral spring in stoppage of an induction motor without depending on the clutch brake.SOLUTION: Direct current is input into a main coil L1 and an auxiliary coil L2 of an induction motor being rotating. This arises magnetic fields in the main coil L1 and the auxiliary coil L2 to electrically stop a rotor R, and then the motor is stopped by a clutch brake, thereby preventing breakage of a motor shaft and wear of the clutch brake. |
