High dynamic moving magnet linear rotation integrated two-degree-of-freedom motor

Abstract

The invention relates to a high-dynamic moving-magnetic type linear rotation integrated two-degree-of-freedom motor. The high-dynamic moving-magnetic type linear rotation integrated two-degree-of-freedom motor comprises a rotor and a stator which are installed coaxially, wherein the rotor comprises a motor shaft, a front magnet ring and a rear magnet ring, the motor shaft, the front magnet ring and the rear magnet ring are installed coaxially, and the front magnet ring and the rear magnet ring are respectively and fixedly arranged on the side face of the outer circumference of the motor shaft in a sleeved mode; the stator comprises a front end cover, a rear end cover, a magnet yoke, a magnet separating base, a brushless motor stator module, a front voice coil module and a rear voice coil module, and the front end cover, the rear end cover, the magnet yoke, the magnet separating base, the brushless motor stator module, the front voice coil module and the rear voice coil module are installed coaxially. The high-dynamic moving-magnetic type linear rotation integrated two-degree-of-freedom motor has the advantages that the rotor can be driven to do liner and rotating combined motion, or do linear motion individually or do rotating motion individually, the rotor is free of an electric brush or a drainage wire, the problems of generating a spark and breaking the drainage wire off are avoided, the service life is long, the maintenance amount is small, a rotating rotor and a linear rotor are integrated into one rotor, and therefore the rotor is simple and compact in structure, small in inertia and good in dynamic property.

Description

technical field [0001] The invention relates to a motor, in particular to a high dynamic moving magnet linear rotation integrated two-degree-of-freedom motor. Background technique [0002] Existing motors generally can only provide single-degree-of-freedom rotary motion (rotary motor) or linear motion (linear motor), while linear-rotary two-degree-of-freedom motors can achieve two-degree-of-freedom linear and rotational compound motion in one motor. [0003] In medical, semiconductor packaging, aviation and other fields, there are a large number of two-degree-of-freedom linear-rotary compound motion requirements, and the motion drive components are required to be small in size and light in weight. The traditional implementation plan is to establish two sets of independent motor systems and their transmissions to drive linear and rotary motions respectively. The system is large in size and slow in response. The rapid development of modern industry puts forward higher and mor...

[0007] The utility model patent "High-Frequency Linear Rotating Motor" (Patent No.: 201020582357.2, Publication No.: 201830127U) is essentially just two single-degree-of-freedom motors installed together, not a true integrated linear rotation with two freedoms high-speed motor, the volume is still large

[0011] The linear rotation two-degree-of-freedom motor provided in the Chinese patent "A Moving-Magnet Linear Rotation Two-DOF Motor" (Patent No.: 2011104202009, Publication No.: 102497080A) realizes the integration of the linear rotation motor, but the mover Structurally, the linear mover and the rotary mover are connected in series, and the linear mover and the rotary mover need to be installed separately during installation, and both the linear mover part and the rotary mover part have a magnetic yoke, which will lead to a large mass of the overall mover , affecting the dynamic performance of the motor

In addition, there is no support on the inner side of the circular rotating mover, and only a cup-shaped magnetic isolation seat is connected to the linear mover, which not only further increases the quality of the mover, but also when the motor is installed horizontally, the mover is in a cantilever state and needs to bear its own The bending moment caused by gravity is prone to deformation, resulting in uneven torque output of the motor and affecting the long-term reliability of the motor
