Abstract

The invention discloses a servo motor, which comprises an output shaft, a pressure sensor, a rotation speed sensor, an oil inlet, a sealing washer, fixed screw holes, a fixing baffle, a heat dissipation plate, an integrated electric box, wiring ports, a transmission shaft, a rotor, an oil seal washer, permanent magnet stators, a hall sensor, an N pole, an S pole, a shielding box, a V interface, aW interface and a U interface, wherein the pressure sensor is arranged in the output shaft; the side edge of the pressure sensor is provided with the rotation speed sensor; the side edge of the rotation speed sensor is provided with the oil inlet; one side of the wiring ports is provided with the transmission shaft; one side of the transmission shaft is connected with a rotor; the oil inlet is a one-way oil inlet channel for preventing leakage of lubricating oil; the fixing baffle and the body are integrally punched; the oil seal washer is made of wear-resisting silica gel to enable the engineto keep sealing effects; the permanent magnet stator is made of an iron nickel permanent magnet; and the shielding box is made of a lead nickel alloy-containing material, thereby shielding outer electromagnetic interference.

Description

technical field [0001] The invention relates to the field of motor products, in particular to a servo motor. Background technique [0002] At present, in the field of motor products, the servo system is an automatic control system that enables the output controlled variables such as the position, orientation, and state of the object to follow the arbitrary changes of the input target. The servo mainly relies on pulses for positioning. Basically, it can be understood that the servo motor After receiving 1 pulse, it will rotate the angle corresponding to 1 pulse to achieve displacement. The servo motor itself has the function of sending pulses, so every time the servo motor rotates an angle, it will send a corresponding number of pulses. In this way, the servo motor accepts The pulses form an echo, or a closed loop. In this way, the system will know how many pulses are sent to the servo motor. The brush motor has low cost, simple structure, large starting torque, wide speed ra...

[0002] At present, in the field of motor products, the servo system is an automatic control system that enables the output controlled variables such as the position, orientation, and state of the object to follow the arbitrary changes of the input target. The servo mainly relies on pulses for positioning. Basically, it can be understood that the servo motor After receiving 1 pulse, it will rotate the angle corresponding to 1 pulse to achieve displacement. The servo motor itself has the function of sending pulses, so every time the servo motor rotates an angle, it will send a corresponding number of pulses. In this way, the servo motor accepts The pulses form an echo, or a closed loop. In this way, the system will know how many pulses are sent to the servo motor. The brush motor has low cost, simple structure, large starting torque, wide speed range, easy control, and requires maintenance. , but the maintenance is inconvenient, electromagnetic interference is generated, and there are requirements for the environment, so it can be used in general industrial and civil occasions that are sensitive to cost. The brushless motor is small in size, light in weight, large in output, fast in response, high in speed, and small in inertia , smooth rotation, stable torque, complex control, easy to realize intelligence, its electronic commutation method is flexible, can be square wave commutation or sine wave commutation, the motor is maintenance-free, high efficiency, low operating temperature, small electromagnetic radiation, Long life, can be used in various environments, but the motor is not like ordinary DC motors, AC motors are used under normal conditions, and the inside of the motor will be damaged due to motor overload and high temperature during use. This new experimental model is mainly to solve The above motor overload and high temperature will damage the motor internally and be susceptible to electromagnetic interference.
