Description
Technical field
The present invention relates to technical field of motors, more particularly, to a kind of squirrel-cage energy-saving electric machine.
Background technology
Squirrel cage motor, it is simple in construction, be generally fixedly connected by casing, magnetic pole of the stator, three big part of cage rotor, magnetic pole of the stator with casing, cage rotor is connected with casing by bearing, and this motor has many advantages, but there is also energy consumption it is higher the problem of.
The content of the invention
It is an object of the invention to provide a kind of squirrel-cage energy-saving electric machine, can effectively improve the efficiency of motor, have good energy-saving effect.
The technical scheme is that：A kind of squirrel-cage energy-saving electric machine, including support, body, drive end bearing bracket, rear end cap, rotating shaft, cage rotor in rotating shaft, stator and winding, tube-axial fan is installed on axle on the outside of the rear end cap, the outside of the tube-axial fan is provided with oval fan housing, the cage rotor includes the rotor core and mouse cage being made up of the stacking of polylith cold-reduced silicon sheet, the mouse cage is double-deck cage-shaped structure, if it is made up of two aluminium alloy end ring and dry copper sliver, two circle manholes are disposed with the outer ledge of the aluminium alloy end ring, the copper sliver inserts in manhole respectively forms double-deck cage-shaped structure, two aluminium alloy end ring are connected with the both ends of rotor core respectively.
Further, the diameter of the two circles manhole is different.
Preferably, the diameter of the manhole of the aluminium alloy end ring in the outer part is more than the diameter of manhole in the inner part.
The present invention has the advantages and positive effects of：
1st, rotor core is laminated by cold-reduced silicon sheet, and cold-reduced silicon sheet has higher magnetic conductivity and relatively low specific loss, can improve air gap flux density, reduces iron loss, improves electric efficiency；
The 2nd, double-deck cage-shaped structure is set, stronger magnetic field can be formed, rotor torsion and motor efficiency can be improved, there is more preferable energy-saving effect；
3rd, the end ring of mouse cage uses aluminum alloy materials, and sliver uses copper product, utilizes conducting electricity very well for copper, density is big, and the density of aluminium is small, low-cost feature, meet the requirement of squirrel cage motor electrical property and mechanical performance simultaneously, and reduce manufacturing cost, reach energy-efficient purpose；
4th, the windage of motor outer ventilation circuit is smaller, and radiating airflow predominantly axially, using the tube-axial fan that pressure head is low, air quantity is big, and is equipped with oval fan housing, and drafting efficiency is high, and noise is low, can significantly reduce wind friction loss.
