Abstract

The invention relates to a multi-surface cylinder type hybrid excitation switch magnetic flux linear motor. A multi-stator modularized structure is designed, so that the machining and assembling of the motor are more convenient and simple; magnetic steel and windings are arranged on stators of the linear motor, so that the material consumption and the cost of the linear motor are reduced; a motor rotor only has movable sub-tooth rings, so that the linear driving robustness of motor is high, and the response is rapid. According to the invention, the excitation windings are set, so that the magnetic field of the motor is adjusted, and the low-speed loading and high-speed feeding performance of the linear motor is improved; in addition, a cooling liquid circulation system is arranged, the magnetic steel, an armature winding and the excitation windings are enabled to dissipate heat together, and the operation load and stability of the linear motor are substantially improved, so that compared with an existing linear motor, the linear motor serving as a servo direct driving force source of a main shaft large thrust axial driving type has more advantages, and the working performance is better.

Description

technical field [0001] The invention relates to a linear motor, in particular to a multi-face cylinder type hybrid excitation switch magnetic flux linear motor. Background technique [0002] In the existing high-end CNC machinery and equipment, the permanent magnet linear motor instead of the "rotary servo motor + ball screw" spindle linear drive method has the advantages of high linear speed, fast instantaneous response, and high linear positioning accuracy, and is becoming more and more widely used. application. The existing AC permanent magnet synchronous linear motor has excellent control performance and is widely used in the feed system of various CNC machine tools. However, this type of motor has disadvantages such as low efficiency, low thrust density, and high cost of the motor, making it difficult to apply to linear drive applications for spindles that require high thrust. [0003] In view of the above technical problems, it is necessary to provide a new type of h...
