Abstract
The utility model discloses a direct current motor stator used for decorating a ceiling fan, comprising a stator core composed of multiple groups of silicon-steel plates. Periphery of the stator is provided with multi-group teeth having same specification, wire casing apertures for fixing winding coils are formed among the teeth of the stator core. The top of the teeth is an outer circle cambered surface of the stator core, two sides of each tooth are inclined planes with inclination by certain angle, and adjacent inclination planes among teeth of the stator core form a non-uniform air gas portion of the stator core. External form of the stator core is a non-uniform circle, the adjacent inclined planes among the teeth of the stator core and a permanent magnet ring of a motor rotor form the non-uniform air gas portion, because of that, when a dead point position occurs in the direct current motor, an additional magnetic resistance moment is generated to start the motor in a self-start manner; and to eliminate dead point by electromagnet moment synthesis effect generated with the winding, so continuous moment is obtained in one rotation circle to maintain continuous work.
