METHOD OF FIXING PULSE ENCODER TO MOTOR AND PULSE ENCODER-CARRYING MOTOR

摘要

In order to fix a pulse encoder to a motor, a stationary code plate (20) is attached temporarily to an end portion (18) of a motor housing (12), and the motor housing (12) is then turned around a motor shaft (14) so as tQ correct the eccen-, tricity of the stationary code plate (20). A gauge (50) is inserted between the stationary code plate (20) and a rotary code plate (48) to space the rotary code plate (48) from the stationary code plate (20) by a predetermined distance. The motor shaft (14) is then turned with respect to the motor housing (12) so as to correct the eccentricity of the rotary code plate (48) which is attached temporarily to a sleeve (42). If this method is employed, the pulse encoder can be fixed to the motor accurately and efficiently.
