DEVICE FOR ADJUSTING THE ROTATION SPEED OF A SWITCHING MOTOR WITH SERIAL EXCITATION OR SHUNT EXCITATION

摘要

P a) Device for regulating the speed of a motor with a switch, with series excitation or with shunt excitation, over different ranges of speed, in particular for washing machines with low speed of washing and spinning and at higher spinning rotation speeds and for d (other motors with series excitation.b) Device characterized in that two or more field coils (2, 3) are provided which can be put into circulation separately or in common and at least one field winding (3, 21) of which contains a socket on field winding. c) The invention gives a washing machine greater convenience in switching between the different speeds washing and spinning as well as better acceleration behavior. /P
