description A method for manufacturing a direct current motor having a stator and a rotor. The stator has a first number of slots, and the rotor includes a permanent magnet having a second number of alternately magnetized poles. The method includes calculating a magnetization pattern based on a magnetizing construct associated with said direct current motor, which magnetizing construct includes a hypothetical magnetizing stator having the same number of magnetizing teeth as the second number of alternately magnetized poles. The method further includes having the permanent magnet magnetized with substantially the calculated magnetization pattern, thereby forming the direct current motor.
