Abstract
PURPOSE: To promote a cost down for production with an extension work eliminated of an output shaft for the purpose of generator installation, by an arrangement to enable the speed generator provided within a front cap of the motor.
CONSTITUTION: In an external face part of motor front cap 118 is provided a hole part 121 concentrically with the output shaft, and a speed generator is housed within said part. This generator comprises a rotor, made of generator magnet 102 secured to an output shaft 110 of the motor, a yoke 103, installed in a circumferential part of the hole part 121 in the front cap 118 and secured to the front cap 118, and a stator that consists of coils. In this way, as the speed generator is capable of being installed in the front cap of the motor, an extension of the output shaft will not be required for the purpose of installation of the generator, and a precision of output signal of the speed generator will not be deteriorated by a cause of the output shaft extension, simultaneously with a cost down capable for production of the output shaft
