Servo motor with protection structure

Abstract

The invention discloses a servo motor with a protection structure, and relates to the technical field of driving motors, and the servo motor comprises a motor body assembly, a heat dissipation and cooling assembly and a rotation speed detection assembly. The heat dissipation cooling assembly comprises a rear-end inner ratchet wheel, a rear-end outer ratchet wheel, a front-end inner ratchet wheel, a front-end outer ratchet wheel, a rear-end gear set, an outer-end gear ring, a large gear and a rear-end heat dissipation fan, the rear-end gear set, the outer-end gear ring and the large gear are all rotationally installed on the rear machine base, and the rear-end inner ratchet wheel and the front-end inner ratchet wheel are fixedly installed on a motor shaft in a stacked mode; the rear-end inner ratchet wheel is meshed with the rear-end outer ratchet wheel, the input end of the rear-end gear set is in gear fit with the rear-end outer ratchet wheel, and the output end of the rear-end gear set is in gear fit with the outer-end gear ring; the rear-end cooling fan is fixedly connected with the outer-end gear ring and can rotate together with the outer-end gear ring, the temperature of the motor in an actual power environment is reduced through rotation of the rear-end cooling fan, the demagnetization threshold value is increased, and demagnetization is reduced.

Description

technical field [0001] The invention relates to the technical field of drive motors, in particular to a servo motor with a protective structure. Background technique [0002] Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an executive element, and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into the motor shaft. angular displacement or angular velocity output. Servo motors are divided into two categories: DC and AC servo motors. The main feature is that when the signal...

Problems solved by technology

[0003] In order to overcome the shortcomings of the weak protection of the motor body in the prior art, the Chinese utility model patent with the publication number CN212163002U discloses a drive motor with a shell protection mechanism, including a drive motor body, the front and back of the drive motor body are horizontal A reinforcement plate is bolted, and a guide cylinder is bolted to both sides of the front and back of the reinforcement plate. A guide column, the end of the guide column away from the limit spring is bolted to the first protective plate

Although the device achieves the effect of elastic buffer protection, the temperature of the servo motor will gradually rise during operation, and the servo motor will demagnetize when it is in a high temperature state for a long time. This device cannot solve the problem of demagnetization caused by high temperature
