Abstract
The utility model 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, and a cylinder is arranged outside the magnetic ring and is fixed in the end cover of the motor; and the inner side of the magnetic ring is provided with an inner stator, the side of the inner stator close to the magnetic ring is provided with an integrated circuit board with an integrated encoder circuit, and the magnetic field direction of the cylinder corresponds to the position of a circuit with an encoder sensing magnetic field on the integrated circuit board. Since the encoder is integrated in the DC brushless motor, the utility model solves the problem that the encoder can not be arranged in the common motor structure. With the motor, the encoder and the outer wheels integrated into one module, the utility model greatly reduces the size and weight of the wheels and facilitates the maintenance. Moreover, the utility model has the advantages of low rotating speed and large torque, and can be widely applied in the field of the automatic tracking robot.
Description
Technical field
The utility model relates to a kind of road brushless electric machine, a kind of specifically 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 be installed in installing space have only 10 millimeters less than small space.This just need redesign the structure of existing encoder and dc brushless motor.
The utility model content
The purpose of this utility model provides a kind of dc brushless motor with encoder, and the installing space that solves traditional motor is narrow and small, and encoder can not be installed, need be in the problem of the outside additional encoder of motor.
The purpose of this utility model 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; In the inboard of magnet ring is internal stator, 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 promptly produces A, B, Z three-phase signal, and the magnetic field of magnet ring and magnetic post is not subjected to the influence in the magnetic field of motor own, does not influence 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 dwindled the installation dimension and the weight of wheel greatly, 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.
