Biaxial motor and biaxial driving method

Abstract

A dual-axis motor, comprising a casing, a mover shaft, at least three mover core groups, and at least three stator cores, the mover shaft extends axially and can translate axially and rotate circumferentially relative to the casing; Each mover core group includes at least one mover core. The mover core is fixedly sleeved on the mover shaft and distributed at intervals along the axial direction. The mover core protrudes outward to form a plurality of mover teeth arranged at intervals in the circumferential direction. ;Each stator core includes at least two stator pole groups, each stator pole group includes at least one stator pole, and each stator pole is wound with a conductive coil; any mover core group is opposite to the stator core in the axial direction When the mover cores of other groups are axially staggered with the stator cores; when multiple stator teeth of any one stator pole group are opposite to the mover teeth in the circumferential direction, the stator teeth of other groups of stator poles are in the circumferential direction. Stagger upward with the mover teeth. The biaxial motor of the present invention has high efficiency and high precision because it does not use screw rods or transmission gears.

Description

technical field [0001] The invention relates to the field of motors, in particular to a biaxial motor and a biaxial driving method. Background technique [0002] Dual-axis (two-degree-of-freedom) drive has important applications in many fields, such as in photovoltaic power generation systems, in order to adapt to changes in sunlight angles, real-time adjustment of the lighting surface to obtain maximum lighting efficiency; also in the engraving industry Among them, the multiple control of the cutter head of the automatic engraving machine; the dual-axis drive also has potential application prospects in the field of 3D printing. The traditional dual-axis drive is mainly realized by combining two rotating motors or linear motors in different directions. The motor using this driving method must use multiple screw rods or transmission gears, and due to the tooth backlash The existence of the gear or the energy loss caused by the transmission of the screw leads to the lower dri...

The traditional dual-axis drive is mainly realized by combining two rotating motors or linear motors in different directions. The motor using this driving method must use multiple screw rods or transmission gears, and due to the tooth backlash The existence of the gear or the energy loss caused by the transmission of the screw, which makes the driving accuracy and driving efficiency of the motor lower
