Beschreibung
Zusammenfassung:	The utility model provides a power apparatus of an electric locomotive brake system. The power apparatus comprises an AC motor. An input end of the AC motor is connected with a frequency converter, and an output end of the AC motor is connected with an actuating member in a brake device. The motor in the brake device is the AC motor which replaces a DC motor, thereby overcoming a series of problems caused by the DC motor. The AC motor is low in starting current, almost has no arc, is low in failure rate, is nearly maintenance-free, helps to ensure that a locomotive runs normally, and also enables energy to be saved. Moreover, the AC motor and the frequency converter together are lower in price than the DC motor. Therefore, the power apparatus is an ideal option for main traction equipment for transporting minerals and instruments in coal mines, and underground main tunnels or galleries of metallurgy mines.
