Continuous-rotation high-angular position accuracy digital motor

Abstract

The invention relates to a continuous-rotation high-angular position accuracy digital motor. The continuous-rotation high-angular position accuracy digital motor includes a driving motor, a harmonic reducer, a magnetic encoder, a servo driving controller and a shell; the stator of the driving motor, the magnetic encoder and the servo driving controller are fixed on the shell; the first output end of the rotor of the driving motor is connected with one end of the harmonic reducer through screw threads; the other end of the harmonic reducer is the torque output end of the driving motor; magnets of the magnetic encoder are fixed to the second output end of the rotor of the driving motor; the input end of the servo driving controller is connected with the output end of the magnetic encoder; the output end of the servo driving controller is connected with external connection control signals; and the power supply end of the servo driving controller is connected with the input end of the driving motor. The rotation precision, rotation angle and output torque of the continuous-rotation high-angular position accuracy digital motor are higher than those of a general servo. The continuous-rotation high-angular position accuracy digital motor has the advantages of low cost, high precision and high output torque.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a continuously rotating digital motor with high angular position accuracy. Background technique [0002] At present, known steering gear structure is made up of motor, driver, potentiometer, reduction gear set and rudder disc. The steering wheel is connected with the external load, the steering gear is fixed, and the torque of the motor is amplified and output through the reduction gear set. Most of the steering gears are driven by multi-stage reduction gears, the reduction gear set is not strong enough, and it is easy to be damaged when the external load is large. [0003] The connection between the rudder plate and the steering gear on the market is not reliable. It is only fixed by a small modulus spline and an end screw. The output is unstable, resulting in unbalanced load and easy damage. [0004] The controllable angle of most domestic steering gears is around ...

Most of the steering gears are driven by multi-stage reduction gears, the reduction gear set is not strong enough, and it is easy to be damaged when the external load is large

[0003] The connection between the steering wheel and the steering gear on the market is not reliable. It is only fixed by a small modulus spline and an end screw. The output is unstable, resulting in unbalanced load and easy damage.

[0004] The controllable angle of most domestic steering gears is about 180 degrees, which cannot continuously rotate for a full circle, and cannot meet the current demand for steering gears in the robotics field.
