The AC induction motor is the dominant motor technology in use today, representing more than 90 percent of installed motor capacity. Induction motors are available in single-phase (1ϕ) and three-phase (3ϕ) configurations, in sizes ranging from fractions of a horsepower to tens of thousands of horsepower. They may run at fixed speeds – most commonly […]
Induction machines are also called asynchronous machines i.e. the machines which never run at a synchronous speed. Whenever we say induction machine we mean to say induction motor. Induction motors may be single-phase or three-phase. In this article, I am discussing about three phase induction motor construction. The three-phase induction motors are the most commonly used
The no load test and the blocked rotor test are two main induction motor tests, which are performed on induction motor to know the different losses, power factor and efficiency of the induction motor. No Load Test of Induction Motor The no load test of 3 phase induction motor is performed on induction motor when
