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
The present invention relates to a kind of dc brushless motor, specifically a kind of dc brushless motor with encoder.
Background technology
The motor that encoder is installed in the market mostly is the structure of internal rotor, external stator.And dc brushless motor is internal stator, outer-rotor structure, and axle is fixed; And encoder need to be installed in interior installing space and only has 10 millimeters less than small space.This just need to redesign the structure of existing encoder and dc brushless motor.
Summary of the invention
The purpose of this invention is to provide a kind of dc brushless motor with encoder, the installing space that solves traditional motor is narrow and small, and encoder can not be installed, need to be in the problem of outside motor additional encoder.
The objective of the invention is to be achieved through the following technical solutions:
A kind of dc brushless motor with encoder comprises motor shaft, is installed in the bearing on the motor shaft, in the installed inside of described bearing magnet ring is arranged, and in the external position of magnet ring a magnetic post is set, and described magnetic post is fixed in the end cap of motor; Be internal stator in the inboard of magnet ring, the integrated circuit board of integrated encoder circuit is installed near a side of magnet ring at internal stator, the position that has the circuit of encoder induced field on the corresponding integrated circuit board of the magnetic direction of described magnet ring and magnetic post, rotation namely produces A, B, Z three-phase signal, and the magnetic field of magnet ring and magnetic post is not subjected to the impact in the magnetic field of motor own, does not affect the waveform of output.Described magnet ring and magnetic post are fixed in the end cap of motor, and integrated circuit board is fixed on the electric motor internal stator.
This patent is integrated in dc brushless motor inside with encoder, has solved the problem that electric machine structure commonly used can't be installed encoder.This dc brushless motor wheel is integrated into a module with motor, encoder and foreign steamer, has greatly dwindled installation dimension and the weight of wheel, and is easy to safeguard; This dc brushless motor has the characteristics of the slow-speed of revolution, high moment of torsion simultaneously, will be widely used automatic tracking robot field.
