Abstract

The invention relates to a recombination current driven nine-phase plane motor, a linear-rotating motor and a driver thereof, which belong to the field of motors and motor control. The invention solves the problems that the prior plane motor and the linear-rotating motor have complex structures, low system efficiency, difficult control and the like. The armature coils of the plane motor and the linear-rotating motor are divided into nine groups, each group of the coils are connected in series to form nine phase armature windings which are in star connections, permanent magnets of the motors have array structures, the opposite angles of permanent magnet units are adjacent to each other, parallel with each other, and vertical but not adjacent to each other, and the permanent magnets at the same line or row have same polarities while the permanent magnets at adjacent lines or rows have opposite polarities. The plane motor and the linear-rotating motor have the advantages of small volume, simple insulation between winding phases, large thrust output of unit volume, quick dynamic response, small positioning force and large active cell motion range. The recombination current driven nine-phase plane motor, the linear-rotating motor and the driver are applicable to driving plane two-dimensional movements and linear-rotating two-dimensional movements, and are particularly applicable in the field of precise driving.

Description

technical field [0001] The invention relates to a composite current-driven motor and a controller thereof, belonging to the field of motors and the field of control thereof. Specifically, it relates to a high-thrust density planar motor and a linear-rotary motor. Background technique [0002] Modern precision and ultra-precision processing equipment has an urgent need for high-response, high-speed, high-precision planar drive and linear rotary drive devices, such as machining, electronic product production, mechanical loading and unloading, machining, manufacturing automation instrumentation equipment, and even robot drives Wait. Usually these devices are powered by a rotary motor, and then the rotary power generated by the motor is converted into linear motion by mechanical devices such as belts and ball screws. Due to the complex structure of the mechanical device, the transmission accuracy and speed are limited, and frequent adjustments are required, which have the disa...
