Title:
IRON CORE OF MOTOR
Document Type and Number:
Japanese Patent JP2000014055
Kind Code:
A
Abstract:
To provide an iron core of a motor which can improve motor efficiency when an air gap between a stator core and a rotor core is reduced.
A tip part 7 of a tooth part core 5 turning to the inner periphery of a stator core 8 to which a rotor core 2 faces via an air gap 6 is constituted as a sawtooth form for increasing the surface area. Thereby practical magnetic flux density of the air gap 6 is reduced, so that an iron core of a motor which can improve motor efficiency when the air gap 6 between the stator core 8 and the rotor core 2 is reduced can be obtained.
