Problems solved by technology

The linear motor based on magnetic field modulation has been developed rapidly due to its advantages of compact structure, high power density and high efficiency, but there is coupling between the phases of the magnetic field, and the fault tolerance performance is reduced. Therefore, a transverse flux magnetic field modulation is proposed. On the one hand, the armature winding and the stator slots are perpendicular to each other in space, which realizes the decoupling of the electric load and the magnetic load, and can increase the output by increasing the rate of change of magnetic energy within a certain range; on the other hand, each phase They are decoupled from each other, which is convenient for independent control, and is easy to design into a multi-phase structure. In multi-phase operation, even if one phase is missing, it can work normally. The fault tolerance performance is good, and the reliability of the motor is improved.

Embodiment Construction

[0021] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0022] Please refer to figure 1 As shown, it is a schematic structural diagram of the transverse magnetic flux magnetic field modulation type linear motor of the present invention. The transverse magnetic flux magnetic field modulation type linear motor includes: a primary and a secondary; the present invention combines magnetic field modulation on the basis of transverse magnetic flux In the proposed field-modulated motor, the two secondary stages are formed by stacking silicon steel sheets in a "C" shape and are arranged in a mirror image, so that there is three-sided air between the primary and the secondary. There are no cumbersome armature windings on the inner three sides of the "C" shape, but multiple secondary slots 1 and multip...

Abstract

The invention discloses a transverse flux magnetic field modulation type linear motor. The linear motor comprises primary bodies and secondary bodies. The two secondary bodies are in a C-shaped, mirror image arrangement, and three air gaps are arranged among the primary body and the secondary bodies. The inner sides of the secondary bodies are provided with a plurality of secondary grooves and a plurality of secondary teeth at equal intervals, and secondary permanent magnets are disposed in the secondary grooves. Each of the primary bodies comprises two same primary iron cores and a connecting beam used for connecting the two primary iron cores. The upper surfaces and the lower surfaces of the primary iron cores and the surfaces of the primary iron cores back to the connecting beams are provided with salient pole teeth, which are arranged at equal intervals, and are the same. The salient pole teeth are provided with salient armature windings in a coiled manner, and are provided with virtual teeth, and virtual grooves are arranged among adjacent virtual teeth, and in addition, virtual groove permanent magnets are disposed in the virtual grooves. Virtual groove armature windings are disposed in the virtual grooves. The three phases of the primary bodies are provided with three phases of armature windings. The armature winding of the same primary body is used to form one phase, and the armature windings of the three primary bodies are used to form three phases, and a difference among currents flowing through the three phases is 120degrees. The transverse flux magnetic field modulation type linear motor adopts modularization design, and has advantages of simple structure, and ability of improving fault-tolerant performance.
