特徴とする高頻度用ブレーキ電動機の冷却機構。[Claims for Utility Model Registration] In a cooling mechanism for a high-frequency brake electric motor having a completely enclosed external fan-shaped cooling fan; It is supported on the rotor shaft via a compound one-way ball bearing clutch, and when the rotor shaft drives the cooling fan in a direction for cooling, the cooling fan and rotor shaft engage in the clutch and become integral. When the rotor shaft rotates and the rotor shaft is braked, the clutch engagement between the cooling fan and the rotor shaft is released, and the cooling fan rotates due to inertia to continue cooling.
A cooling mechanism for a high-frequency brake motor, which is characterized by being designed to reduce braking impact.
