Problems solved by technology

It can be seen that the traditional coil winding method has two leads for each coil, which requires a lot of wiring work, increases the joint resistance, and due to the discontinuous nature of the coil in space, the generated traveling wave magnetic field is also discontinuous. , the end effect of the mover in the motion process results in power loss

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 2 The primary of the cylindrical asynchronous straight line shown in the present invention, the ABC three-phase wires are continuously spirally wound at 120° in the circumferential direction to form a winding 1, and its lead wire 2 can be as follows: figure 2 shown distributed at both ends of the winding, it can also be as image 3 As shown, one end of the winding goes out, which is called the outlet end, corresponding to the A, B, and C three-phase leads at the inlet end, and the leads at the outlet end can be called -A, -B, and -C, respectively. The other end of the winding, which may be referred to as a blind end, such as Figure 4 As shown, at the blind end, the three-phase wires are respectively transposed 180° apart in the circumferential direction and wound back in the same helical direction. ° Corresponding re...

Abstract

The invention discloses a primary winding of a cylindrical asynchronous linear motor. The primary winding is characterized in that: the primary winding is a spiral winding, and is formed by continuously spirally winding a three-phase wire at the interval of 120 degrees along a circumferential direction in form of constant diameter spiral line. When wound to an end part, the three-phase wire is wound back along a spiral direction the same as that of the wire of the upper layer after 180-degree transposition, and repeated operations are performed to realize the winding of a multi-layer multi-turn wire. Lead wires at the leading-out end of the three-phase wire are all distributed at one end of the primary winding. The primary winding is wound in a constant pitch way or a variable pitch way.

Description

technical field [0001] The invention relates to a primary winding of an asynchronous linear motor. Background technique [0002] Linear motors can achieve linear motion of components without going through the mechanical transmission conversion mechanism required by rotary motors. From the structure of the primary (stator) of the motor, the linear motor is divided into a flat plate type and a cylindrical type. The former primary is a planar winding, and the latter is a coaxial solenoid coil. The role of the primary is to spatially generate a traveling wave magnetic field that moves along the direction in which the primary windings are arranged. In terms of operating principles, linear motors are divided into synchronous and asynchronous types. The speed of the secondary pole (also called the mover) of the former is the same as the speed of the traveling wave magnetic field, while the speed of the latter mover is different from the speed of the traveling wave of the magnetic ...
