Abstract
The invention relates to a permanent magnet motor low-carbon steel hollow circular pipe type rotor structure which is provided with a rotor sleeve, a shaft extension end axle, a non shaft extension end axle, screws, arc-shaped magnetic steel, anaerobic adhesive and carbon fiber cloth. Two ends of the rotor sleeve are respectively fastened with the shaft extension end axle and the non shaft extension end axle through front edges and the screws. An external circle of the rotor sleeve is adhered with the arc-shaped magnetic steel through the anaerobic adhesive, and a magnetic steel external circle is winded with the carbon fiber cloth and is subjected to heat-curing. When using the permanent magnet motor low-carbon steel hollow circular pipe type rotor structure, the arc-shaped magnetic steel is uniformly distributed on an external circle of the rotor sleeve, and a problem that a multi-polar permanent magnet motor rotor is not easy to employ built-in magnetic steel is solved, especially a problem that a moment of inertia requirement of a rotor is small in a servo motor is solved. The permanent magnet motor low-carbon steel hollow circular pipe type rotor structure is reasonable in structure, simple, convenient and practical, and especially is suitable for a large power permanent magnet motor synchronization moment servo motor.
Description
Technical field
The present invention relates to a kind of motor rotor construction, specifically a kind of magneto mild steel open circles tubular type rotor structure.
Background technology
We know that at present, permanent magnet machine rotor adopts the rotor sheet of punching silicon-steel to laminate into rotor core more, and portion inserts magnet steel within it, and is promptly built-in.If the interior permanent magnet machines number of poles is too many, magnet steel is difficult on the rotor punching and distributes.And punching out silicon steel rotor punching complex process, the mold that needs to make punch die and press folded punching.Particularly the moment of inertia of rotor is big, is difficult for control flexibly on servomotor.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of mild steel open circles tubular type rotor structure that is applicable to the rotor external pasting circular arc magnet steel that magnet steel is external and rotor moment of inertia is little of multipolar dynamo is provided.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of magneto mild steel open circles tubular type rotor structure is provided with rotor sleeve, shaft extension end axle, non-shaft stretching end axle, screw, circular arc magnet steel, anaerobic adhesive, carbon cloth.It is characterized in that: the rotor sleeve two ends are fastening with shaft extension end axle and non-shaft stretching end axle respectively by seam and screw, and the rotor sleeve cylindrical is pasted the circular arc magnet steel with anaerobic adhesive, and the magnet steel cylindrical twines carbon cloth and is heating and curing.
The said rotor sleeve of the present invention is the mild steel hollow circular-tube.
The present invention is said fastening with diaxon and rotor sleeve with screw, and wherein trip bolt is a soket head cap screw, locatees with taper pin when fastening.
The present invention has solved the problem that multipole permanent magnet machine rotor is difficult for adopting built-in magnet steel owing to adopt said structure, has particularly solved in the servomotor the little difficult problem of rotor requirement moment of inertia.The present invention is rational in infrastructure, simple, and is convenient and practical, is specially adapted to high-power permanent magnet synchronous torque servo motor rotor structure.
