Basic requirements for transformer silicon steel sheets in electric motors
Scale of rotor bars and end rings, ③ add magnetic flux in the air gap. The conductivity of the conductor and end ring is used to reduce the losses of the rotor winding.
Basic requirements for saving electric motors, with a large range of power changes. However, electric motors often operate below their rated power, and generally the power curve of electric motors is unstable and varies greatly with the load. So the power curve for saving electric motors should be as flat as possible.
The power loss should be reduced by 30% and calculated based on the rated power.
The internal losses of the motor should be minimized as much as possible when designing and manufacturing the motor. The primary technical measures to improve the power of the electric motor are as follows:
Change the processing technology of silicon steel sheets (silicon steel sheets), ① reduce the thickness of silicon steel sheets (silicon steel sheets). Reduce iron core losses.
Add the number of wires in the slot, and ② add the dimensions of the stator slot. Reduce the length of the winding end, etc.
