Title: Brake system for ac motor
Inventor: MIYAMA YOSHIO
IPC: H02P3/24
Filed: 1991-03-01
Abstract: PURPOSE:To reduce heating value by applying a DC voltage, lowering with time, on the winding of an AC motor isolated from an AC power supply. CONSTITUTION:AC voltage of a commercial power supply is stepped down through a step-down transformer 9 and rectified through a rectifier 11. The rectified output is then passed through capacitors 17, 15 to produce a smoothed DC voltage. At the same time, the capacitor 15 is charged through a resistor 13. The charging operation sustains during brake interval as well as the rotational interval of a motor 7 but since the charging rate is limited by the resistor 13, total voltage across the capacitor 15 drops with time when a monostable multivibrator 19 is producing an output and thereby the motor 7 current decreases with time. In such a manner, rotation of the motor 7 can be controlled quickly by feeding a DC current to the winding of the motor 7. According to the invention, heating value can be reduced at the time of braking the motor 7.
