Abstract

The invention discloses a servo motor capable of efficiently shielding high-frequency interference. The servo motor comprises a servo driver, a screw rod and an anti-high-frequency interference box, wherein the screw rod is driven by the servo driver; the anti-high-frequency interference box covers the outside of the servo driver; a through hole is formed in the box wall of the anti-high-frequency interference box; the screw rod extends out of the anti-high-frequency interference box through penetrating through the through hole; the servo driver is arranged on the inner bottom surface of the anti-high-frequency interference box through a shock-resistant suspension assembly; the shock-resistant suspension assembly comprises a connection screw rod; a mounting part, a convex shoulder and a sleeve part are sequentially arranged on a rod body of the connection screw rod; the mounting part is connected with the bottom of the servo driver; the sleeve part is sequentially sleeved with a cover board, a metal rubber spring ring, a mounting base and a mounting plate; the cover board and the metal rubber spring ring are sequentially clamped and pressed between the convex shoulder and the mounting base; the mounting plate is connected with the tail end of the sleeve part through a fastener; a plurality of springs are arranged at the bottom surface of the mounting plate; and the plurality of springs vertically extend and are connected to the inner bottom surface of the anti-high-frequency interference box. The servo motor has high shielding property and high accuracy and quality, and is low in cost, efficient and energy-saving.

Description

technical field [0001] The invention relates to a servo motor, in particular to a servo motor capable of efficiently shielding high-frequency interference, and belongs to the technical field of motor equipment. Background technique [0002] Servo motor is an engine that controls the operation of mechanical components in a servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal 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 actuator, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal Converted to angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and...
