Multiple-choice question (multiple selections): Asynchronous motors have ( ) losses. A. Stator copper loss ； B. Stator iron loss ； C. Mechanical loss ； D. Power loss. ABC
Asynchronous motors have (BC) losses. A. Stator copper loss ； B. Stator iron loss ； C. Mechanical loss ； D. Power loss.
In ABC three-phase asynchronous motors, there is 1: copper loss, which is the loss generated when current flows through the motor windings, expressed as a thermal effect. 2: Iron loss, the loss incurred when the magnetic flux lines generated by the motor windings pass through highly magnetic materials, as well as the portion that escapes naturally. 3: Mechanical loss, the loss resulting from mechanical friction during the operation of the motor, which is also expressed as heat generation. Compared to three-phase asynchronous motors, transformers have one less component during operation, namely mechanical loss.
