Negative power induction motor
WebJan 20, 2024 · An induction generator is an induction machine that works as a generator when the slip becomes negative. And then it starts supplying energy back to the main supply. The operation of the induction machine depends on the value of the slip. When the slip is positive, the machine operates as an induction motor. WebOct 1, 2024 · The power, equal to difference of Input and output power, is known as Power loss or Losses in 3 3 phase induction motor. The different type of losses are—. 1. Core Loss:-. · It is an electrical power loss. The magnetic part of the motor is called the Core. Thus the loss occurs in Core is called Core loss. · Core is a magnetic material.
