Abstract
The invention discloses a formula of a magnetic slot wedge. The formula comprises the following components in percentage by mass: 8.97 to 12.1 percent of F51 heat-resistant epoxy, 2.2 to 2.9 percent of bismaleimide resin, 3.8 to 4.96 percent of curing agent, 0.03 to 0.04 percent of 2-methylimidazole accelerator, 3.5 to 6.1 percent of iron sesquioxide, 2.7 to 3.9 percent of ferroferric oxide, 53 to 58 percent of iron powder, 0.3 to 1 percent of iron-nickel alloy, 0.5 to 1 percent of iron-silicon alloy and 10 to 20 percent of glass cloth. The formula of the magnetic slot wedge with high bending strength and high elastic modulus for a motor is designed; the heat resistance and the elastic modulus of the magnetic slot wedge are improved by using the heat-resistant epoxy and the bismaleimide; and the magnetic slot wedge has high magnetic inductivity by using the iron sesquioxide, the ferroferric oxide, the iron powder, the iron-nickel alloy, the iron-silicon alloy and the like. The formula of the magnetic slot wedge can reduce the temperature rise of a running generator by 10 to 20 DEG C, reduce the noise by 20 to 50 decibels and improve the effectiveness of a motor by 1 to 2 percent so as to prolong the service life of the motor and reduce the maintenance cost.
Description
Technical field
The invention belongs to the insulating material field, relate to a kind of magnetic slot-seal, especially a kind of prescription of magnetic slot-seal.
Background technology
Slot wedge is to have gone up insulating effect at motor stator core or character iron core (winding-type), thereby and its be used for the sealing groove mouth prevent that coil from coming out in groove.But magnetic slot-seal inside conducting part magnetic flux makes that field flux distribution is tending towards evenly in the air gap, thus can reduce noise of motor and vibration, and motor oscillating alleviates, and can prolong bearing life again.When notch is put into magnetic slot-seal, its effect is equivalent to motor effective air gap contraction in length, therefore can reduce magnetizing current, no-load current is descended, reduce the wastage, if the output rating of motor is constant, after then loss reduces, the input wattful power of motor can reduce, and received current also decreases; If input wattful power is constant, then the output rating of motor can increase, and also just is equivalent to increase the capacity of motor.
In sum, the existence of slot wedge can make electrical efficiency improve, and reduces the loss of electric machine, and amount descends to make that the motor feels hot, thereby prolongs motor work-ing life.
But, magnetic slot-seal of the prior art is because poor heat resistance, physical strength is low, permeability is low, use in motor and get rid of the groove phenomenon, these shortcomings seriously limited magnetic slot-seal motor a large amount of uses, therefore, a kind of magnetic slot-seal with good thermotolerance, high strength and high permeability of development is that electromechanics trade is desired.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of prescription of magnetic slot-seal is provided, the prescription of this kind magnetic slot-seal is by each component of reasonable configuration, be in operation temperature rise and noise of generator reduced, and can improve electrical efficiency, thereby improve the work-ing life of motor, reduce maintenance cost.
