Battery type absolute value encoder and motor

The utility model discloses a battery type absolute value encoder, which relates to the field of detection, solves the problem of a standby power supply of the battery type absolute value encoder by embedding a battery on a circuit board of the battery type absolute value encoder, and can improve the reliability of the battery by directly embedding the battery into the circuit board. It is guaranteed that loosening is avoided in practical application, loss of internal data is avoided, data safety is guaranteed, loss of field work is reduced, meanwhile, the embedded connection mode does not have the situation of external lines, a power supply line does not need to be reserved independently, loss of the battery caused by the length of the line and the resistance of the line is avoided, and the service life of the battery is prolonged. Therefore, the service life of the battery is prolonged, the installation volume is reduced, the installation is more convenient, the application range of the battery type absolut
