Abstract

The invention provides a magnetic encoder, a motor and an angle calculation method of the motor. The magnetic encoder comprises a magnetic conducting disk, annular magnet steel fixed in the magnetic conducting disk and an encoder plate, wherein four linear hall elements which are uniformly distributed in the circumferential direction are arranged on the surface of the encoder plate; all linear hall elements are located in a cavity enclosed by the annular magnet steel; and the encoder plate is provided with an encoder algorithm control circuit connected with all linear hall elements. The annular magnet steel is fixed in the magnetic conducting disk and the linear hall elements are arranged in the annular magnet steel, so that the maximum anti-interference performance is achieved and the signal output accuracy of the linear hall elements is improved.

Description

technical field [0001] The invention relates to the technical field of encoders for motors, in particular to a magnetic encoder, a motor and an angle calculation method thereof. Background technique [0002] Magnetic encoder is a new type of encoder developed in recent years. Compared with photoelectric encoders, it has obvious advantages in miniaturization, anti-vibration, high frequency response, and low cost. At present, the low-priced magnetic encoders on the market are mainly low-precision and low-resolution. The encoder is an independent device, which is not highly integrated with the controller and has very high requirements for the mechanical installation position. Therefore, it is difficult to apply to Sewing machine systems with high precision requirements. [0003] Chinese patent 201611205360.0 relates to a sewing machine driver and a sewing machine. A magnetic encoder system for a sewing machine drive includes a magnetized disk and alternating north and south ...
