General-purpose rotary encoder

A general-purpose rotary encoder, comprising:

• a MR sensor unit for outputting mechanical angle information of rotation angle of a rotation axis of a DC motor;
• a mechanical angle-electric angle signal converter for converting output information of the MR sensor unit into signal information for generating a drive signal of the DC motor;
• and
• a non-volatile memory,
• wherein the mechanical angle-electric angle signal converter comprises:
• an incremental type mechanical angle-electric angle signal conversion unit that converts the output information of the MR sensor unit into an incremental signal for generating the drive signal of the DC motor, and
• an absolute type mechanical angle-electric angle signal conversion unit that converts the output information of the MR sensor unit into an absolute signal for generating the drive signal of the DC motor,
• the non-volatile memory has signal conversion data as initial setting data for converting the output information of the MR sensor unit into the incremental signal or the absolute signal for generating the drive signal of the DC motor, which corresponds to a type of the DC motor to which the rotary encoder is mounted, and the mechanical angle-electric angle signal converter is configured to convert the output information from the MR sensor unit into the signal for generating the drive signal of the DC motor based on the signal conversion data, during operation of the DC motor.
