PURPOSE:To reduce the variation in the torque of an electric machine by increasing the interval of the part that which crosses the effective magnetic flux of the part which forms a phase different to that adjacent to the part which crosses the effective magnetic flux of an armature coil wider than the interval of the part which has lower magnetic flux density which is produced in the boundary of poles. CONSTITUTION:A motor has an armature 6 and a rotor 1 as a movable element. The armature 6 has an armature core 7 and an armature coil. The core 7 has slots S1-S36 disposed at an equal interval. The armature coil is not filled in the slots which are formed between the slots in which coils forming a different phase such as slots S2, S5, S8..., and idle slots are formed. The interval of the slots which are disposed at both sides of the idle slot is wider than the width of the part which has lower magnetic flux density formed between the poles. |
