Novel magnet-gathering type transverse flux permanent magnet linear motor

Abstract

The invention discloses a novel magnet-gathering type transverse flux permanent magnet linear motor which comprises stators and a rotor. The rotor is rectangular and is composed of two salient pole iron cores and a connecting board. The two salient pole iron cores are fixed to the two ends of the connecting board respectively and respectively provided with a groove. The groove of each salient pole iron core is provided with a permanent magnet and a winding. Multiple strip-shaped air grooves with equal intervals are evenly formed inside each stator. The salient pole iron cores at the two ends of the rotor are arranged in the two stators respectively. According to the novel magnet-gathering type transverse flux permanent magnet linear motor, a primary level and a secondary level are respectively of a salient pole structure, the independence between phases is good, and the high force density and fault tolerance are integrated; the use rate of stator space is high; the fault tolerance capacity is strong and operation reliability is high; fluctuation of the locating force and the pushing force is small and the control characteristic is flexible; the permanent magnets are placed in the primary-level rotor iron cores, so that the temperature is easy to control, the permanent magnet use amount is small, and the motor can be applied to the field with the high requirement for reliable operation of a system.
