Single winding pairs of speed three different step motor
ABSTRACT：Become many speed three different step motor for have grade transfer speed motor , it is it change stator winding connect law change number very much of motor already to utilize extremely, make motor is it get two or two more than rotational speed to come with one or two winding. Whether can know according to rotational speed characteristic , reaction of motor to transfer speed way have 3 big classes it. Frequency is regulated , magnetic pole logarithm is regulated and transfers to the difference rate regulating . It designs to be single winding pairs of speed asynchronous motor originally, it counts to be 4/6 very much, than speed of transfering each. Design originally become winding very much for become winding very much backward.
Become many speed three different step motor extremely because of is it can afford to grade with demand for load nature to have, reach to match and is it change speed the systematic characteristic to simplify rationally power. Motor suitable for various types of omnipotent make up , not special-purpose to cut lathe and mine metallurgy , textile , chemical industry , agricultural machinery ,etc. department is it transfer various kinds of transmission organization of speed step by step to needing.
KEYWORDS：There is grade that adjusts speed，Stator winding，Grading
