High-thrust modularized permanent magnet linear synchronous motor

Abstract

The invention discloses a high-thrust modularized permanent magnet linear synchronous motor. A stator mechanism is provided with a plurality of stator modules which are arranged in a linear mode, and each stator module is provided with a magnetic conductive block and a conductive coil arranged on the magnetic conductive block in a sleeving mode. A mover mechanism is provided with two first mover modules and a second mover module, and each first mover module is provided with a first magnetic conductive plate movably arranged beside one long edge side of the stator mechanism and a plurality of first permanent magnets arranged on one side of the first magnetic conductive plate. The second mover module is provided with a second magnetic conductive plate movably arranged above the stator mechanism and a plurality of second permanent magnets arranged on the lower side surface of the second magnetic conductive plate; when the conductive coil is connected with an external power supply, the two first mover modules and the second mover module can move together along the length direction of the stator mechanism. According to the permanent magnet linear synchronous motor, the high thrust function is realized, the manufacturing cost is reduced, the size of the motor is reduced, and the permanent magnet linear synchronous motor can be well applied to automatic equipment or high thrust motion occasions.

Description

technical field [0001] The invention relates to the technical field of motors, and specifically provides a high-thrust modular permanent magnet linear synchronous motor. Background technique [0002] The traditional "rotary motor + lead screw" indirect drive method has disadvantages such as backlash, poor reliability, and friction; while permanent magnet synchronous linear motors have the advantages of non-contact transmission, high response, and high speed, so in recent years, permanent magnet synchronous linear motors have Motors are gradually being used in automated production equipment. [0003] In order to achieve high-precision operation of the motor, a permanent magnet linear motor without cogging is usually used, but its thrust is not enough; and in order to achieve a larger thrust operation, a permanent magnet linear motor with an iron core is usually used. In order to further increase the thrust, in many In the application, the double-sided flat permanent magnet l...

Problems solved by technology

[0004] However, in the current commonly used double-sided flat permanent magnet linear motor structure, although the armature volume of the motor is reduced compared with the two single-sided types, the overall motor volume and cost are reduced very little, and the unit is usually added to increase the thrust. The number of motors, the number of coils, etc., but the utilization rate of the windings has not improved, and the space and cost have not been effectively improved
