Abstract

The invention discloses a DC brushless motor with an encoder, which comprises a motor shaft and a bearing arranged on the motor shaft; the inner side of the bearing is provided with a magnetic ring, a magnetic column is arranged outside the magnetic ring, and the magnetic column is fixed in an end cover of the motor; and the inner side of the magnetic ring is provided with an inner stator, one side of the inner stator which is close to the magnetic ring is provided with an integrated circuit board for integrating the circuits of the encoder, and the magnetic field direction of the magnetic column is provided with a position of the circuit of an encoder sensing magnetic field corresponding to the integrated circuit board. The invention integrates the encoder into the DC brushless motor, and solves the problem that the encoder cannot be arranged in a commonly used motor structure. A DC brushless motor wheel integrates the motor, the encoder and an outer wheel into a module, thereby greatly reducing the installation size and the weight of the wheel, and facilitating the maintenance; and simultaneously, the DC brushless motor is characterized by low rotating speed and high torque, and is widely applied in the field of automatic tracking robots.

Description

technical field [0001] The invention relates to a DC brushless motor, specifically a DC brushless motor with an encoder. Background technique [0002] At present, most motors equipped with encoders on the market have the structure of inner rotor and outer stator. The brushless DC motor has an inner stator and outer rotor structure, and the shaft is fixed; and the encoder needs to be installed in a small space of less than 10 mm. This requires redesigning the structure of existing encoders and DC brushless motors. Contents of the invention [0003] The object of the present invention is to provide a DC brushless motor with an encoder, which solves the problem that the traditional motor has a narrow installation space, cannot install an encoder, and needs to add an encoder outside the motor. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A DC brushless motor with an encoder, comprising a motor shaft and a be...
