Title:
STATOR, MOTOR COMPRISING THE SAME, AND METHOD FOR MAKING THE SAME
Document Type and Number:
Japanese Patent JP2017189093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a stator with enhanced winding efficiency that can be more conveniently fabricated, and a motor having the stator.SOLUTION: A motor stator includes a stator core and a large number of stator windings. The stator core includes a stator yoke and a plurality of stator teeth wrapped by a bobbin formed by an over-molding process, and further correspondingly wound around by stator windings. The stator teeth are connected to an inner surface of the stator yoke. A motor including the motor stator and a rotor is also provided. The rotor includes a rotor core and a rotary shaft fixed relative to the rotor core. The rotor core is received in the bobbin and in magnetic coupling with the stator teeth.SELECTED DRAWING: Figure 4
