Abstract

PURPOSE:To adjust the revolution speed and change the command easily when the operation is started by controlling the revolution of the first braking member electrically. CONSTITUTION:The induced voltage of a generating winding 16 rises when the revolution speed of a permanent magnet 12 rises by the revolution rise of a pinion shaft 7. When the induced voltage reaches the specified value a pulse generating element 20 becomes conductive and makes a thyristor 21 conductive. With this process, a large currentIflows through the generating winding 16 with a resistor R2 as a load. The large torque is generated in the generating winding 16 to the same revolution direction as the pinion shaft 7 in accordance with this load current an a brake-shoe 15 is rotated to the direction of an arrow A. As the slope 15A-1 of the brake-shoe 15 faces and contacts the slope 17A of a brake cover 17, when the brake-shoe 15 is rotated, the brake shoe 15 is pushed out to the direction of an arrow B. The brim of the brake- shoe 15 presses a brake-wheel 10 against a brake-disc 13 and the braking is applied to the pinion shaft 7.
