Abstract
The invention relates to a three-phase asynchronous motor special for YZS series injection molding machines. The three-phase asynchronous motor is mainly characterized in that: a front end cover and a rear end cover are fixedly connected with a motor shell; a motor shaft is supported in the motor shell by a bearing assembly; a rotor is arranged on the motor shaft; a stator is arranged on the motor shell; a fan is fixed on the motor shaft; and a fan cover is fixed on the rear end cover. The three-phase asynchronous motor is characterized in that: an axial end of the motor shaft extends out of the front end cover; and a key is arranged in a key groove in front of the motor shaft. A wave-shaped spring is arranged between the bearing assembly and the front end cover; an elastic retainer ring for a hole is arranged between the bearing assembly and the rear end cover; the upper part of the stator is connected with a junction box through a bolt; and a gap is formed between the stator and a rotor core. The three-phase asynchronous motor can reduce the cost and raw materials, has high power, can improve the starting torque, can eliminate synchronous accessory torque and rotor harmonic field, is favorable for reducing electromagnetic noise, can improve the starting torque and reduce non-uniformity of the air gap of the motor, and can improve the process flow and processing assembly quality.
Description
Technical field
The present invention relates to a kind of YZS series three-phase asynchronous motor special for injection molding machine, specifically be used to drive injection molding machine equipment.
Background technology
In prior art, the threephase asynchronous that matches with injection machine (based on four utmost points, sextupole), its load is not specified during work, but one from unloaded, fully loaded cyclic variation process to overload.Its normal requirement has low noise, detent torque high-performance when transshipping, injection molding machine not only requires motor full-load run, and require the motor short-time overload to move (the maximum overload multiple is 1.75 times), therefore, most of common motors do not satisfy this requirement, therefore need a kind of definite purpose motor and injection molding machine supporting.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, can eliminate synchronous annex torque and rotor harmonic field, help reducing electromagnetic noise thereby provide a kind of; Can improve detent torque, reduce the three-phase asynchronous motor special for injection molding machine of motor air gap unevenness.
According to technical scheme provided by the invention, three-phase asynchronous motor special for injection molding machine adopts front end housing, rear end cap and motor casing to be connected into electric machine casing, motor shaft is supported by bearing assembly and is installed in the electric machine casing, rotor is installed on the motor shaft, stator is installed on the motor casing, and fan is fixed on the motor shaft, and fan housing is fixed on the rear end cap, feature is: motor shaft end stretches out front end housing, fitting key in the keyway of motor shaft front.The wavy spring sheet is set between described bearing assembly and front end housing; Between described bearing assembly and rear end cap circlip for hole is set.
Connect terminal box by bolt above the described stator.
Be provided with the gap between described stator and rotor core.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Can reduce cost and raw material; Power is big, can improve detent torque; Can eliminate synchronous annex torque and rotor harmonic field, help reducing electromagnetic noise; Can improve detent torque, reduce the motor air gap unevenness, and can improve technological process and process and assemble quality.
