MOTOR

摘要

A motor that is provided with a motor unit and an amplifier unit, said motor unit being equipped with a coil-wound stator and a rotor which is provided inside the stator so as to drive a rotary shaft to rotate, and said amplifier unit being integrated with the motor unit so as to supply driving power to the motor unit, wherein the motor unit and the amplifier unit are electrically and mechanically connected together with screws via a wiring pedestal, the pitch diameter of multiple electrical connection parts of the wiring pedestal, said electrical connection parts being arranged on a circumference formed around the axle center of the rotary shaft and connected to the motor unit, is smaller than the pitch diameter of multiple electrical/mechanical connection parts which are connected to the amplifier unit, the amplifier unit is created by providing multiple circuit boards in layers in the direction perpendicular to the rotary shaft, and the multiple circuit boards are electrically and mechanically connected, with screws via a conductive spacer, to the multiple electrical/mechanical connection parts of the wiring pedestal which are connected to the amplifier unit.
