The utility model relates to an elevator encoder technical field especially relates to a magnetic encoder, including the OTP register that has the zero point position parameter of motor, link to each other with the OTP register, utilize the zero point position parameter, carry out the corrector of adjusting to the zero point position of encoder signal, and link to each other with the corrector, encoder signal after outside output is revised to the external tapping. Above technical scheme with the zero point position parameter prestore of motor in the OTP register to the confession corrector uses, has effectively utilized the intrinsic OTP register of magnetic encoder itself, compares the extra memory of interpolation among the prior art, is showing the manufacturing cost that has reduced magnetic encoder and the use cost of motor. And simultaneously, the utility model also provides a motor, including above -mentioned magnetic encoder, the beneficial effect ditto.
