Motor stator winding resistance losses: reduce motor stator windings of the stator resistance is the primary means to reduce losses, the practice of using more methods are: (1) increasing the cross-sectional area of ??the stator slots, in the same outer diameter of the stator, an increase in the stator slots will reduce the cross-sectional area of ??the magnetic circuit area YE2 motor, increased tooth portion flux density; (2) the rate of increase in the stator slot full tank, which is better for low-voltage motors small, winding and insulation applications best size, large conductor cross-sectional area can be increased stator slot full rate; and (3) minimize the stator winding end of the minister, the stator end winding winding loss account the total loss of 1/4 to 1/2, to reduce the winding end of the minister, the motor efficiency can be improved. Experiments show that the end of the 20% reduction in speed motor minister loss decreased by 10%. Motor iron loss loss: loss of motor iron losses can be reduced by the magnetic density export motor (1), increase the length of the core to reduce the magnetic flux density, but the motor is increased by the amount of iron; (2) to reduce the thickness of the laminations reduce the loss of the induced current, such as cold-rolled silicon steel sheet instead of hot-rolled steel sheet thickness can be reduced, but the thin iron chip will increase the number of chips and motor manufacturing iron Chen this; (3) the use of a good magnetic properties of cold rolled silicon steel lower hysteresis loss; (4) the use of high-performance laminations insulating coating; the remaining stress (5) heat treatment and manufacturing technology motor laminations after processing will seriously affect the loss of the motor, silicon processing, cutting direction greater influence of shearing stress on the core loss. Silicon steel rolling mill along the direction of cutting, heat treatment and silicon steel sheet can be reduced by 10% to 20% of the loss, and other methods to achieve.
