A switch 3 can select between the contacts a, b, c, and "off" position. Preferably, the resistance of the resistor 22 is smaller than that of the resistor 23. Contacts a, b and c are formed on the common end of the windings 11, 12 and resistors 22 and 23, the other end of the resister 22 and the other end of the resistor 23. Two resistors 22, 23 with different resistances are connected to the windings 11, 12 respectively. 3, the primary winding 11 and the secondary winding 12 are connected in parallel, and/or a capacitor 18 is connected to the secondary winding 12 in series. People are annoyed by such noise especially during the night. In such construction, using either contact a or b produces an unbalanced electromagnetic field and creats excesive noise. The secondary winding 12 is separated into three sections with intermediate contacts at a and b.
It is difficult and time consuming to bring the wires of those terminals A to H out from the stator during manufacturing. Terminal H connects to terminal B after connecting with a capacitor. The terminals A and C, D and E, F and G respectively form the contacts c, b and a. The secondary winding 12 is wound in the outer slots and consists of three sections each terminating in two terminals C to H. 6, the primary winding 11 is wound in the inner slots of a stator and terminates in the two terminals A and B. 5 it can be seen that a number of contacts a, b and c are electrically connected to the windings 11 and 12 for determining several rotating speeds of the ceiling fan. Normally, a circuit of a ceiling fan has a primary winding 11 and a secondary winding 12 electrically connected in parallel.
