Title:
STATOR FIXING STRUCTURE
Document Type and Number:
Japanese Patent JP2005304213
Kind Code:
A
Abstract:
To provide a stator fixing structure that can effectively suppress electromagnetic noise generated by a magnetic reactive force at the time of driving a motor.
The whole external peripheral part of a stator core 12 is pressed by an annular end plate 20. By this, the whole external peripheral part of the stator core 12 is uniformly pressed, thereby suppressing the electromagnetic noise. Furthermore, there can be employed such methods as: pressing the middle part between fixing parts of the stator core by a pressing plate (preferably wedge-shaped); arranging the fixing parts of the stator core in the radial direction at unequal intervals; and spreading the width of the middle part between fixing parts of the stator core.
