Anti-high frequency interference servo motor

Abstract

The invention discloses an anti-high frequency interference servo motor which comprises a servo driver, a screw rod driven by the servo driver and an anti-high frequency interference box covering the servo driver, wherein a through hole is disposed in the box wall of the anti-high frequency interference box, the screw rod passes through the through hole in order to be extended out from the anti-high frequency interference box, and the servo driver is installed on the bottom inside the anti-high frequency interference box by an anti-seismic suspension assembly; the anti-seismic suspension assembly comprises a connecting screw rod, the rod body of the connecting screw rod is successively equipped with an installation part, a raised shoulder and a sleeving part, and a floating rotary ball is connected to the tail end of the connecting screw rod; and the installation part is connected to the bottom part of the servo driver, the sleeving part is successively sleeved by a cover plate, a metal rubber spring, an installation base and an installation plate, and the cover plate and the metal rubber spring are successively clamped and pressed between the raised shoulder and the installation base. The anti-high frequency interference servo motor provided by the invention can still be used normally under a high frequency (high harmonic wave) or an electromagnetic wave, has high shielding performance and high precision, and is low is cost, efficient and energy-saving.

Description

technical field [0001] The invention relates to a servo motor, in particular to a high-frequency interference-proof servo motor, which 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 AC servo motors. Its mai...
