<p>PURPOSE:To reduce the shock of vibration at the stopping time by simultaneously employing an electric brake and an electromagnetic brake. CONSTITUTION:A resistor 4 which is connected in series with the contact of a relay 6 is connected in parallel with an armature 2 as a load of the armature 2 in a conveying vehicle which is controlled by a control circuit 3, the contact of a relay 6 is closed by a brake signal, and an electric brake is applied. When a timer 5 which is operated by the brake signal is elapsed in the prescribed period of time, the contact of the relay 6 is opened to release the electric brake, and the contact of a relay 7 is simultaneously opened, an electromagnetic brake 8 is operated and completely stopped.</p> |
