Example Embodiment

[0030] The present invention will now be described in further detail with reference to the drawings.

[0031] Such as figure 1 with figure 2 As shown, the new double Ω-type stator transverse flux permanent magnet linear motor includes a stator (denoted as S) and a mover (denoted as M). The stator includes an Ω-type stator core group (denoted as S1), armature winding S2 and non The stator base of magnetic material, the mover includes mover core M3, permanent magnet (denoted as M4) and non-magnetic material mover bracket M5.

[0032] The Ω-type stator core group includes a plurality of lower opening stator cores S11 and a plurality of upper opening stator cores S12 with opposite openings. The lower opening stator core S11 and the upper opening stator core S12 are installed inside the stator base of non-magnetic material. The sub-movements are evenly spaced and staggered in the forward and backward directions. Among them, the lower opening stator core S11 and the upper opening stato...

Abstract

The invention discloses a novel double-omega type stator transverse flux permanent-magnet linear motor with high power density, high performance and direct driving performance. The motor comprises a stator (S) and a mover (M), and has a mover motion direction vertical to a magnetic return path plane; and two groups of stator cores are integrated on a same armature to ensure that the structure of the motor is more compact and the space utilization rate is remarkably improved. Through such design, the torque density of the motor can be effectively improved, and the difficulty of manufacturing the stator and the mover can be reduced. Due to the electromagnetic structure decoupling feature of the motor, a multiphase motor can be constructed easily and phase-deficient operation can be carried out through transversely arranging a plurality of same mover-stator structures side by side, so that the motor is suitable for the field of electric traction of railway vehicles.

Description

technical field [0001] The invention belongs to the field of transverse flux motors, and in particular relates to a novel double Ω stator transverse flux permanent magnet linear motor with a double Ω stator core staggered structure. Background technique [0002] With the rapid development of society, the rapid expansion of urban scale, and the increasingly serious environmental pressure, rail vehicles have gradually become the mainstream of public transportation. As the core equipment of rail vehicles, the electrical and mechanical properties of the traction motor are directly related to the system efficiency and reliability. At the same time, the use of low-speed permanent magnet direct drive motors is a major trend in the development of rail systems in the future, and its advantages such as high efficiency, high reliability, long life, low noise, and low operation and maintenance costs are gradually emerging. Therefore, the focus of the industry is the development of new ...
