Abstract
The utility model provides a high strength heat-resisting insulating high magnetic conductivity slot wedge, includes the magnetizer, wraps the insulating layer in the outside of magnetizer, the magnetizer constitute by many wires that set up side by side, many wires bond as an organic wholely mutually. The magnetizer has the advantages of high magnetic permeability, high mechanical strength and high heat resistance, can improve the performance of the motor, reduce the amplitude of magnetic conduction harmonic, reduce the iron loss and the tooth pulse loss on the surface of the rotor, reduce the heating amplitude of the motor, improve the electromagnetic noise and the starting performance when being applied to a high-voltage motor, and has great significance for reducing the energy consumption of the motor and improving the efficiency.
Description
Technical field
The utility model relates to the slot wedge that uses on a kind of motor.
Background technology
In the prior art, the high-voltage AC motor stator slot adopts the open slot structure, have that air-gap permeance is inhomogeneous, the problems such as amplitude increase of magnetic conductance harmonic wave, make rotor surface iron loss and dyke loss increase, motor temperature raise big, decrease in efficiency, electromagnetic noise is big, starting performance is poor.Existing part motor adopts magnetic slot-seal, this magnetic slot-seal is the laminated sheet that Magnaglo (as iron powder) is filled usually, motor properties is had some improvement, but the stock utilization of this magnetic slot-seal is low, bad mechanical strength, permeability are low, so be difficult to promote the use of.
Summary of the invention
The utility model purpose provides the high magnetic conduction slot wedge of a kind of high strength anti thermal insulation, and its mechanical strength is higher, permeability is high, can reduce the motor power consumption, raise the efficiency.
For achieving the above object, the technical solution adopted in the utility model is: the high magnetic conduction slot wedge of a kind of high strength anti thermal insulation, comprise magnetic conductor, wrap in the insulating barrier in the outside of described magnetic conductor, described magnetic conductor is made up of the many wires that are provided with side by side, and described many one metal wires are bonded as one mutually.
Because technique scheme utilization, the utility model compared with prior art has following advantage: magnetic conductor adopts many mutually bonding wires, it has high permeability, high mechanical properties, the advantage of high-fire resistance energy, can obviously improve motor properties when being applied on the high-voltage motor, reduce the amplitude of magnetic conductance harmonic wave, alleviate rotor surface iron loss and dyke loss, reduce motor intensification amplitude, improve electromagnetic noise and starting performance, be significant for reducing the motor power consumption and raising the efficiency, also can reduce electromagnetic interference simultaneously, improve the stable and fail safe of electrical network.
