Three-phase, one-third pitch motor

机译:三相三分之一变桨电动机

摘要

A three-phase motor is disclosed which has six salient teeth for a two- pole motor or twelve salient teeth for a four-pole motor. The motor stator has at least three main field windings on the salient teeth to form either two or four poles, with the teeth being equal in number to at least three times the number of the poles. Each main field winding includes on one tooth a first coil connected in series with the second coil on another tooth, so that at a given instant, pole faces of opposite polarity are established on these two teeth. The coils of the at least three main field windings are wound and connected so that each coil is a one-third pitch of three adjacent teeth, with pole faces of the same polarity at a given instant. The end result is that these three main field windings establish a uniform rotating field to provide driving force to a rotor. The three-phase motor stator is wound by winding a first coil clockwise, and then relatively indexing the winding head and the stator by 180 electrical degrees before winding the second coil counterclockwise. The first and second coils are wound in series without breaking the conductor and this provides a method of economically manufacturing a small three-phase motor. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be constructed as a limitation on the scope of the claimed subject matter.
