The hooded pole motor
The hooded pole motor is the simplest type of one way-ac motor. According to the different stator shape and structure, it is divided into the salient pole type and the hidden pole type.
The stator core of a salient pole motor is a square, rectangular or circular magnetic field frame with a protruding magnetic pole. The central winding on the salient pole magnetic pole acts as the main winding.
Non-salient pole type cover pole motor stator core is the same as the common core of single-phase motor. The stator winding adopts the distributed winding. The main distribution in stator slot winding and shaded pole winding don't short circuit copper ring, but the coarser the enameled wire wound as distributed winding (series after short circuit) embedded in the stator slot (about two-thirds of the total number of slots), with a support group. The main winding and the enclosure winding are spaced at a certain Angle.
When the main winding of the hooded motor is energized, the hooded winding will also generate induction current, so that the magnetic flux and unhooded part of the magnetic field of the covered part of the magnetic field of the magnetic field of the covered part of the magnetic field of the magnetic field of the covered part of the magnetic field that will rotate to the direction of the covered part.
