Problems solved by technology

The literature Orthogonal magnetic field analysis of a double-stator linear-rotary permanent magnet motor with orthogonally arrayed permanent magnets (IEEE Transactions on Magnetics, 53(11): 2501104, 2017) proposes a radially inner and outer double-stator linear-rotary permanent magnet motor. The degree of magnetic field coupling at the mover core is relatively serious, and the fault tolerance performance is poor

Abstract

The invention discloses a double-stator linear rotation two-degree-of-freedom fault-tolerant permanent magnet cylinder motor which has linear, rotary and spiral motion capabilities. Comprising an outer stator, a rotor and an inner stator. The outer stator iron core (1), the outer stator permanent magnet (2), the winding (31) of the rotary motion part and the rotor iron core (4) form a rotary motion unit; and the rotor inner side permanent magnet (6), the inner stator iron core (7) and the winding (32) of the linear motion part form a linear motion unit. The fault-tolerant permanent magnet motor adopts an inner and outer double-stator structure and is provided with an inner air gap and an outer air gap, magnetic flux paths of the linear winding and the rotary winding are mutually independent, and flexible decoupling control of linear and rotary motion and spiral motion control can be realized.

Description

technical field [0001] The invention relates to a double-stator straight-line rotation two-degree-of-freedom fault-tolerant permanent magnet cylindrical motor, which is suitable for applications requiring linear, rotary and helical motion drives, and belongs to the technical field of special motors. Background technique [0002] With the increasing complexity of modern industrial systems and the continuous improvement of driving precision requirements, more and more occasions require two-degree-of-freedom driving. At present, two-degree-of-freedom drives are mostly realized by combining multiple single-degree-of-freedom motors through mechanical transmission devices. The system has low positioning accuracy, complex control systems, and poor fault redundancy and fault tolerance. The two-degree-of-freedom motor avoids complex mechanical combinations and mechanical gaps, and can better meet driving requirements. [0003] Linear rotary permanent magnet motor is a two-degree-of-...
