The invention provides a phase group concentrated winding magnetism gathering type rotary linear motor, which sequentially comprises an inner stator, a motor rotor, an outer stator and a motor shell which are coaxially arranged from inside to outside, wherein the motor rotor is a hollow cylinder, one end of the motor rotor is connected with an output shaft of the motor, and the motor rotor and theoutput shaft of the motor are coaxial; the inner stator is located at the hollow position of the motor rotor and provided with an inner stator coil winding used for driving the motor to rotate; and the outer stator is positioned outside the motor rotor, is provided with an outer stator coil winding and is used for driving the linear motion of the motor. The motor has the advantages of less permanent magnet consumption, simple structure, high air gap flux density and small mutual influence of linear motion and rotary motion.
Description
technical field [0001] The disclosure belongs to the field of motor design and manufacture, and in particular relates to a phase-group concentrated winding and magnetism-concentrating rotary linear motor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In the current control field, with the improvement of control requirements and the diversification of motion forms, the motor demand for multi-degree-of-freedom motors is also increasing. In order to solve these problems, more and more domestic and foreign scholars have started the research on multi-degree-of-freedom motors, and proposed various multi-degree-of-freedom motor topologies. Compared with multiple single-degree-of-freedom motor combination mechanisms, the multi-degree-of-freedom motor system has the advantages of compact structure, high material utilization rate, light total we...
