Parking Crossing Gate Having Braking System of Permanent-Magnet Synchronous Motor for Automatic Vehicle Barrier Gate and Method Working the same

摘要

The present invention relates to a parking brake device having a braking device for a permanent magnet type synchronous motor for a vehicle gate breaker and a blocking bar operation angle adjusting device. More specifically, the motor braking torque is calculated by considering the voltage limitation condition of the DC link capacitor at the time of braking of the parking breaker motor having the braking device of the permanent magnet type synchronous motor for the vehicle gate breaker and the voltage limitation condition input by the inverter To a parking brake device having a brake device for a permanent magnet type synchronous motor for a vehicle gate breaker and a parking bar operation angle adjusting device capable of stable braking control for a motor even at a low speed and a high speed rotation of the blocking bar.
