bike motor variable speed control method of pole pairs is used to change the wiring to the stator windings to change the cage motor stator pole pairs to achieve speed control purposes, the following features:
1, with a hard mechanical properties, good stability;
2, non-slip loss, high efficiency;
3, the wiring is simple, easy to control, low prices;
4, class speed, a larger differential, can not get smooth speed control;
5, with speed regulator, used in conjunction with electromagnetic slip clutch, to obtain a higher efficiency of smooth speed control characteristics.
This does not require stepless speed control method for the production of machinery, such as metal cutting machine tools, lifts, lifting equipment, fans and pumps.
