Abstract

The invention provides a linear motor structure, comprising: a linear motor body, including a mover and a stator, the mover has a mover end face; the stator includes a stator mounting plate and a magnetic steel, the magnetic steel is arranged on the stator mounting plate, and the magnetic steel has The side surface of the magnet steel and the end surface of the magnet steel, the end surface of the magnet steel and the end surface of the mover are arranged opposite to each other along the first preset direction; the brake assembly, the brake assembly is arranged on the mover, the brake assembly includes a moving part and a first friction part, the second A friction part has a first separation position separated from the magnetic steel and a first braking position adsorbed on the side of the magnetic steel. The first friction part is arranged on the moving part; the moving part is movably arranged to drive the first friction part Moves between a first detent position and a first disengaged position. The linear motor structure of the present invention solves the complicated problem that the braking system of the linear motor in the prior art cannot make full use of the magnetic force of the magnet steel.

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 ...
