Extension shaft servo motor capable of preventing moisture condensation

Abstract

The invention discloses an extension shaft servo motor for preventing moisture condensation, and belongs to the technical field of the electric motor. The extension shaft servo motor for preventing condensation controls the temperature difference by using the feature of the warming speed under the cooperation of a dehumidification function shell and a condensation lug, thereby realizing a way capable of guiding the moisture condensation; when the servo motor works, hot air adjacent the stator is in moisture condensation on the condensation lug, and the water drop produced after the moisture condensation is collected by using an ultra-strong moisture absorption ball; compared with the traditional heat insulation, air circulation and like suppression measures, the harm caused by uncontrolledmoisture condensation in the servo motor can be obviously reduced by utilizing a way of controlling the moisture condensation through guiding, thereby guaranteeing the normal running of the servo motor, and prolonging the service life thereof.

Description

technical field [0001] The invention relates to the technical field of electric motors, and more specifically, relates to a servomotor with an extension shaft that can prevent dew condensation. Background technique [0002] The motor is a device that converts electrical energy into mechanical energy. It uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric power rotation torque. The motor uses the power supply Differently divided into DC motors and AC motors, most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed), and the motor is mainly composed of a stator and a rotor , The direction of the force-moving wire in the magnetic field is related to the direction of the current and the direction o...

Problems solved by technology

[0004] Generally, when working, the stator in the motor rotates and cuts the magnetic induction line to generate or transmit electric energy. Because the stator rotates to generate heat, it is very easy to make the temperature inside the motor higher than the temperature of the environment outside the motor, and the motor casing of the motor As a structure that isolates the inside and outside of the motor, its temperature is lower than the temperature inside the motor and higher than the temperature outside the motor. When the hot air in the motor is close to the cold motor casing, it will condense into water on the surface. We call this phenomenon Condensation, condensation flowing into the motor can easily affect the normal operation of various parts inside the motor, especially for motors with a protection level of IP55 and above, condensation inside the motor will cause strong damage to the motor casing and internal parts of the motor Corrosion, which seriously affects the safe operation and service life of the motor
