How an Induction Motor Works by Equations (and Physics)
网页induction motors are more popular.) Instead the rotor is wound with shorted turns in which the environmental field induces a current. That current in turn produces a field that interacts with the environment to drive the rotor. The three-phase induction motor is the easiest motor of this type to understand so these notes start with that type.

How to reduce the speed of a single-phase induction motor
网页2017年9月13日0. First be aware that the flow rate of fans relies on the square of the turn speed. So you had to reduce the speed to 70%, not 50%. Unfortunately, the speed of an induction motor is mostly a function of the frequency and it's expensive to change that. The second option would be a resistor in series.
