Speed Control of Three Phase Induction Motor
Cascade speed control
At present, the cascade speed control takes use of SCR inverter cascade control circuit, and has the following advantages: get stronger mechanical characteristic, low rectifier voltage drop, small space, no rotating part, low noise, simple maintenance. It is one of the speed control methods of a wound-type motor.
It also has its own disadvantage. That is, the rotor circuit is equipped with a reactor for the filter, so the power factor is low.
Speed Control of Three Phase Induction Motor
How to control the speed of the three-phase induction motor? The speed control method includes: changing the number of poles, stator voltage control, stator frequency conversion, cascade speed control, double-feed speed regulation, hydraulic coupler, electromagnetic slip clutch, etc.
The actual speed of the three-phase asynchronous motor is given by n=ns (1 - s) =120f /p (1-s). It can be seen from the formula that the speed of 3 phase induction motor can be changed by the means of changing the number of induction motor’s poles "p", the slip "s" and the frequency of power supply"f".
