Title:
ELECTROMAGNETIC BOOSTER
Document Type and Number:
Japanese Patent JPS6130955
Kind Code:
A
Abstract:
PURPOSE:To reduce the weight and the cost, as well as noise and to improve the durability by composing a booster of an electromagnetic type. CONSTITUTION:When an input shaft 8 is rotated and brushes 21, 21 contact commutator segments 14, 15, a current flows to a rotor winding 11 while the brushes 21, 21 contact the segments 14, 15, the current is boosted by the electromagnetic operation of magnets 4, 4 to generate large torque at an output shaft 5, thereby rotating the shaft 5. A rubber 22 is deflected in response to the rotary force applied to the shaft 8, while when torque applied to the shaft 8 is, on the contrary, weakened, the contacts of the brushes 21, 21 with the segments 14, 15 are disconnected by the elastic action of the rubber 2 to stop flowing the current to the winding 11.
