  • Direct-current machine
    Patent number: 4467232
    Abstract: A DC machine (motor, etc.) with permanent field magnets arranged in the stator frame and designed as shells. The shell of each pole structure consists of two or more annular segments arranged one behind the other in the axial direction and staggered with respect to one another in the circumferential direction. The staggered arrangement reduces the excitation flux area between the poles and, thus, diminishes the detent torque of the rotor.
