Embodiment Construction

[0020] As shown in the figure: the modular double-stator switched reluctance linear motor of this embodiment includes a ring-shaped inner stator unit 20, a mover unit 30 and an outer stator unit 10 arranged coaxially from the inside to the outside, and the mover There are set gaps between the unit and the outer stator unit and between the mover unit and the inner stator unit. Since the motor is a switched reluctance linear motor, the interaction between the outer stator unit, the inner stator unit and the mover unit is based on the current excitation applied to the windings, and follows the "minimum reluctance principle" to generate the required thrust;

[0021] In this embodiment, the inner wall of the outer stator unit 10 and the outer wall of the inner stator unit 20 are respectively provided with a stator outer salient pole 11 and a stator inner salient pole 21, and the inner wall and outer wall of the mover unit 30 are respectively provided with The opposite inner salient...

Abstract

A modular double-stator switched reluctance linear motor is disclosed in the invention, and comprises an inner stator unit, a mover unit and an outer stator unit which are coaxially arranged from inside to outside in sequence, and set gaps are formed between the mover unit and the outer stator unit and between the mover unit and the inner stator unit. According to the structure, the outer stator unit and the inner stator unit are arranged in a limited space, the double stator units interact with the mover unit, the required performance can be met by changing the magnitude of winding current and the commutation sequence, complementation between wave crests and wave troughs of thrust of the outer stator unit and the inner stator unit acting on the mover unit is achieved, and the purposes of obtaining high thrust density and reducing thrust fluctuation at the same time are achieved.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a modular double-stator switched reluctance linear motor. Background technique [0002] The most widely used motor type in the field of industrial linear drive is the permanent magnet linear motor, and the permanent magnet linear motor has limited its further development due to its high cost and irreversible demagnetization. The advantages of permanent magnets are expected to become an alternative motor to permanent magnet linear motors. However, switched reluctance linear motors generally have shortcomings such as large thrust fluctuations and low thrust density. Therefore, solving the problems of low thrust density of switched reluctance linear motors has become an urgent need to promote the development of switched reluctance linear motors. Contents of the invention [0003] In view of this, the present invention provides a modular double-stator switched reluctance linear mot...
