How does Liyuan Motor control the temperature rise of YE2 motor?
If possible or necessary, the temperature increase can be effectively controlled by adjusting the electromagnetic parameters, such as reducing the number of turns per slot of the stator winding and increasing the diameter of the conductor, that is, reducing the load of the electromagnetic wire and the current density of the conductor, which is beneficial to reducing the temperature. Raising is very effective. Especially for enclosed motors, when the number of turns of the stator winding is reduced, the copper loss of the stator and rotor is reduced. Although iron loss increases, iron cores dissipate heat more easily than windings. Another problem is that after reducing the number of windings, the power factor will decrease and the starting current will increase. Therefore, it may be necessary to appropriately increase the length of the iron core or change the shape of the rotor slot to improve the overall effect.
For the rotor part, when the magnetic flux density of the rotor core is allowed, the lower area of the slot shape can be enlarged, or the end ring section of the high-speed motor can be increased, especially to reduce the temperature rise and close the stator of the motor.
In order to solve the temperature rise problem, it is necessary to increase the insulation level of the winding reasonably
