Abstract

The invention discloses a bilateral normal electromagnetic actuator with high performance. The bilateral normal electromagnetic actuator comprises a magnetic pole and armatures arranged on two sides of the magnetic pole in a clearance manner, wherein magnet exciting coils are arranged in the magnetic pole and the armatures, a magnet exciting passage is provided for the magnet exciting coils by iron cores and the two armatures, increase or decrease of a permanent magnetic field and normal force is regulated by introducing low current into the magnet exciting coils, switching off and switching on of the electromagnetic actuator or brake are realized, and the problems of high attracting current and holding current, high noise, large size, large dead weight and the like of the electromagnetic actuator and brake such as an electromagnet and the like are solved. The bilateral normal electromagnetic actuator with high performance has the remarkable advantages of simple structure, low cost, stable action, large acting force, small impact, low noise, safety, reliability, small size, light mass, low power consumption, long service life and the like and is convenient to maintain, and the structure of the electromagnetic actuator and brake is greatly simplified. The bilateral normal electromagnetic actuator can be applied to multiple fields of the general electromagnetic actuator and brake, a compressor, hoisting and lifting, a traffic and transport system and the like.

Description

technical field [0001] The invention belongs to the electromechanical field, and in particular relates to a high-performance double-sided normal electromagnetic actuator and a brake or a compressor. Background technique [0002] Electromagnetic actuators such as electromagnets and electric actuators have been widely used in various industries. Taking electromagnets as an example, the existing electromagnets mainly have two structures: electric excitation and hybrid excitation. Permanent magnets are also pasted on to realize the mixed excitation of permanent magnet and electric excitation. The electric excitation structure is the simplest, but the electromagnetic force needs to overcome the entire load force and maintain a large current. The advantage of the hybrid excitation is that the permanent magnetic force helps to overcome a part of the load force and maintain the current reduction after the electromagnet is attracted, but it also brings equivalent New problems such ...
