Description
Technical field
The utility model relates to a kind of threephase asynchronous, is specifically composite rotors self-retention threephase asynchronous.
Background technology
conventional self-retention threephase asynchronous generally comprises support at present, stator, rotor, main shaft, fan blade and brake system, the front end of support is provided with flange, the rear end of support is provided with back cover, rotor is enclosed within on main shaft, fan blade is positioned at the outer end of support and is connected with an end of main shaft, the rotor of this self-retention threephase asynchronous generally adopts solid rotor or cage rotor, when adopting solid rotor, the power of this self-retention threephase asynchronous is lower, torque is less, when adopting cage rotor, although this self-retention threephase asynchronous power is higher, torque is larger, but the large electric current during the direct full voltage starting of this self-retention threephase asynchronous can produce very large impulsive force on the squirrel-cage bar of cage rotor, will cause the squirrel-cage bar fracture, cause this self-retention threephase asynchronous fault.
The utility model content
Technical problem to be solved in the utility model is that the composite rotors self-retention threephase asynchronous that power is higher, torque is large, can not produce very large impulsive force when starting is provided.
For solving the problems of the technologies described above, the composite rotors self-retention threephase asynchronous that the utility model provides, it comprises support, stator, solid rotor, main shaft, fan blade and brake system, the front end of support is provided with flange, the rear end of support is provided with back cover, solid rotor is enclosed within on main shaft, fan blade is positioned at the support outer end and is connected with an end of main shaft, it also comprises cage rotor, solid rotor is provided with the cavity for accommodating cage rotor, cage rotor is fixedly connected with solid rotor, and cage rotor is enclosed within on main shaft.
After adopting above structure, the utility model compared with prior art has advantages of following:
Cage rotor is enclosed within on main shaft, the power of cage rotor is higher, torque is larger, and in cage rotor is arranged on cavity on solid rotor, when this composite rotors self-retention threephase asynchronous is started, cushioning effect due to solid rotor, make cage rotor can not produce very large impulsive force, avoid squirrel-cage bar to rupture and cause this composite rotors self-retention threephase asynchronous fault.
As improvement, described brake system refers to be provided with between solid rotor and back cover can axially movable armature, be combined with spring between the inner face of armature and solid rotor, be provided with friction plate between the outer face of armature and back cover, friction plate is fixed on the outer face of armature, this brake system only has armature and friction plate, and both sides all are arranged on the back cover inboard, namely reduced cost, reduced again volume, when electric motor circuit breaking, rub to reach decelerating effect by friction plate and back cover inner face in support.
