Because of the configuration described above, the following problems exist. That is, since each printed circuit board disposed in the encoder had the height of the encoder substantially equal to the height of the motor case of the motor, the number of each printed circuit board was large due to the mounting area of the electronic components. However, it is difficult to shorten the axial length of the encoder, and the axial direction of the motor encoder is long. Also, since many printed circuit boards are installed in a narrow encoder, the mounting area of each printed circuit board is small, so it is difficult to mount many mounted components, and it is difficult to improve productivity and reliability. there were.
