Title:
位相シフト・コンデンサ付き単相非同期モータを停止する装置
Document Type and Number:
Japanese Patent JP5026652
Kind Code:
B2
Abstract:
The invention concerns a device for stopping the motor when the load on the motor exceeds a predetermined value. It comprises means (D1, DZ, R1, R2) transforming the voltage variation at the phase-shifting capacitor terminals corresponding to a specific torque variation into a selected voltage variation whatever the maximum torque developed, means comparing (T1) the transformed voltage (UB) with a reference voltage and means for stopping the motor when the transformed voltage is less than the reference voltage.
