PROBLEM TO BE SOLVED: To provide an electric machine, in which a laminate of an electromagnetic steel plate having a magnetization facilitating direction taking a direction between a magnetization direction of a main magnetic pole and a magnetization direction of a sub magnetic pole is arranged between the main magnetic pole and the sub-magnetic pole, which can suppress demagnetization of the main magnetic pole without dividing the main magnetic pole from the sub magnetic pole, can be manufactured at a lower cost and can suppress decrease in demagnetization resistance of the main magnetic pole due to decrease in permeance.SOLUTION: A main magnetic pole 21 is arranged on a first face 1 of a yoke 23 so that a magnetization direction takes alternately a direction of a yoke 23 and a direction of a gap G. Sub magnetic poles 22 are magnetized and oriented in a driving direction A and arranged on the first face of the yoke 23 so that the sub magnetic poles face each other through the main magnetic pole 21. A magnetic bundle induction part 24 is constituted by laminating electromagnetic steel plates while matching a rolling direction thereof with a laminating direction, where an angle &thetas; between the rolling direction of the electromagnetic steel plates and the driving direction A is set to a range of 0°<&thetas;<90°. |
