Abstract

Motor eléctrico 10 para un sistema eléctrico de dirección asistida, en la cual una porción 23 de aluminio se forma en el interior de la carcasa del motor 20 para separar un cuerpo de motor eléctrico 10A y una placa de circuito 40 y en la cual el cojinete 25 del eje de salida 11 del cuerpo de motor 10A se sostiene en la porción de montaje 23 para disipar el calor de los FETs 43 de la placa de circuito 40 y el eje de salida 11. Los conductores 36 de las escobillas 33 se sueldan a los terminales de las escobillas de amplia área de superficie para evitar que la placa de circuito 40 alcance una temperatura elevada. Un limitador del par 80 se interpone entre el eje 11 y un eje helicoidal 92 en una carcasa 90 para reducir el tamaño de todo el sistema y la fluctuación periódica del par se suprime corrigiendo la corriente de alimentación al cuerpo del motor eléctrico 10A.Electric motor 10 for an electric power steering system, in which an aluminum portion 23 is formed inside the motor housing 20 to separate an electric motor body 10A and a circuit board 40 and in which the bearing 25 of the output shaft 11 of the motor body 10A is held in the mounting portion 23 to dissipate the heat of the FETs 43 of the circuit board 40 and the output shaft 11. The conductors 36 of the brushes 33 are welded to the brush terminals of wide surface area to prevent the circuit board 40 from reaching a high temperature. A torque limiter 80 is interposed between the shaft 11 and a helical shaft 92 in a housing 90 to reduce the size of the entire system and periodic torque fluctuation is suppressed by correcting the supply current to the body of the electric motor 10A.
