Description

technical field [0001] The invention relates to the fields of a direct-drive transmission, a linear reluctance motor, magnetic levitation technology, and the like, and in particular to a magnetic levitation bilateral reluctance-driven direct linear drive device. Background technique [0002] The "zero transmission" feature of the linear motor direct drive system eliminates the gap, flexibility and other related problems caused by the mechanical transmission of the traditional linear reciprocating motion, simplifies the device structure, improves the transmission accuracy and speed, and is well received by people. general attention. [0003] At present, AC induction linear motors and permanent magnet synchronous linear motors, which are often used in high-power direct linear drives, have problems such as difficult starting, complex speed control equipment, low power factor and efficiency, high manufacturing costs, and poor fault-tolerant operation capabilities. As a new type...

Problems solved by technology

However, due to the introduction of relatively independent magnetic levitation functional components in the mechanical structure of this type of magnetic levitation system, such as special carrying electromagnets, guiding electromagnets, and the magnetic conduction circuits of these electromagnets, etc., the volume and total mass of the device increase, and the mechanical The structure tends to be complex, the number of mechanical parts increases, and the power-to-volume ratio decreases; at the same time, due to the increase in the mass and volume of moving parts, the dynamic response speed decreases, and theoretically inhibits the further increase of the critical line speed of motion
