Stator winding for a miniature brushless DC motor

摘要

In a stator winding for a miniature brushless dc motor comprising a plurality of component windings designed as frame windings injection molded in plastic and nested together in such a manner that they form a cylinder surrounding the permanent magnet rotor of the motor and which can be inserted into a ring-shaped magnetic yoke without slots, the cylinder is formed, on at least one end, with a tubular extension having radial projections which are adapted to engage corresponding recesses at the housing or end bell of the motor for transmitting the reaction moment acting on the cylinder.
