Magnetic suspension linear motor

Abstract

The invention discloses a magnetic suspension linear motor comprising an elastic bracket, and a group including an iron core, a coil and a magnetic module which are disposed inside the elastic bracket, wherein the iron core and the coil are connected to AC to generate an alternating magnetic field; the elastic bracket and the magnetic module, as an integrated body, form a two-vibrator vibration system; and the magnetic module is forced to vibrate under the resultant force of the alternating magnetic field to generate vibration in a linear direction. By using the core coil where AC flows and the alternating magnetic field, the two-vibrator vibration system is formed by the elastic bracket and the magnetic module, and the magnetic module receives the forced vibration generated by the resultant force of the magnetic field in the alternating magnetic field and enables the forced vibration to act on the elastic bracket so as to achieve the reciprocating linear motion of the elastic bracket.The magnetic suspension linear motor solves the cumbersome design where a traditional motor achieve the linear motion by using a crankshaft, and has the advantages of small volume, high motion stability, high reliability and high work efficiency.

Description

【Technical field】 [0001] The invention belongs to the field of micro motors, in particular to a magnetic levitation linear motor. 【Background technique】 [0002] Linear motors have many advantages such as small size, fast start-up speed, low power, simple structure, low noise, low overall cost, and high reliability. [0003] However, the linear motors currently on the market add a crank mechanism to the traditional rotary motor and then convert it into a linear motion. In this way, the volume increases, the structure is complicated, and the amplitude cannot be changed, and the vibration is large, resulting in large vibration. Defects, applied to products will greatly reduce the experience. 【Content of invention】 [0004] In order to solve the existing problems in the background technology, the present invention provides a magnetic levitation linear motor, which overcomes the traditional combination of motor and crankshaft mechanism, and has the advantages of simple struct...
