PURPOSE:To delete the number of machining and assembling a DC electric machine by integrally forming a yoke and an auxiliary pole of a laminated core plate, securing a permanent magnet for forming a magnetic field to the inner surface of the yoke and integrally forming a projection for fixing the magnet at the yoke. CONSTITUTION:Core plates are laminated to form a cylindrical yoke 1. A permanent magnet 2 is secured to the inner peripheral surface of the yoke 1. An auxiliary pole 3 is formed integrally with the yoke 1 on the inner peripheral surface of the yoke 1. Projections 1a, 1b for securing the permanent magnet 2 are formed integrally with the yoke 1. The yoke 1 and a housing are secured via a through bolt 4. |
