Abstract

The invention provides a linear motor structure comprising a linear motor body which comprises a mover and a stator, and the mover being provided with a mover end face, the stator comprising a statormounting plate and magnetic steel, the magnetic steel being arranged on the stator mounting plate and provided with a magnetic steel side face and a magnetic steel end face, and the magnetic steel endface and the rotor end face being oppositely arranged in the first preset direction; a braking assembly, arranged on the rotor, the braking assembly comprising a moving part and a first friction part, the first friction part being provided with a first separation position separated from the magnetic steel and a first braking position attracted to the side face of the magnetic steel, and the firstfriction part being arranged on the moving part; a moving part, movably arranged so as to drive the first friction part to move between the first brake position and the first separation position. Thelinear motor structure solves the problem that a brake system of a linear motor in the prior art cannot fully utilize the magnetic force of the magnetic steel and is complex.

Description

technical field [0001] The invention relates to the field of braking devices, in particular to a linear motor structure. Background technique [0002] For the traditional transmission mode of rotating motor plus screw, since the motor and the working parts have to go through intermediate links such as gears, screw pairs, couplings, etc., there are elastic deformation, backlash, motion hysteresis, friction, vibration, etc. , noise and wear and other problems, and the above problems are difficult to fundamentally solve. Moreover, the operating speed of the above-mentioned transmission mode is relatively low, generally only reaching 30-40 m / min. The linear servo transmission system adopts the direct drive method, which has the advantages of wide operating speed range, high acceleration and high positioning accuracy. The speed can exceed 200m / min, and the acceleration can reach more than 10g. It is especially suitable for precision and high-speed applications, such as high-end ...
