磁ブレーキ。 A yoke that supports a motor shaft and is equipped with an excitation coil, a fan that rotates integrally with the motor shaft, and a cover that guides wind from the fan to the motor through the yoke, and when braking the motor, the In an electromagnetic brake that cuts off power to an excitation coil and energizes the excitation coil when the motor is driven, cooling fins are provided on the outer periphery of the yoke to promote heat dissipation of the excitation coil by wind guided by the motor. An electromagnetic brake characterized by:
