 · The poles of the rotor are almost simultaneously subjected to clockwise and anticlockwise torque thus not allowing the motor to move. By giving a start and increasing the speed to near synchronous we are reducing the relative speed between the rotating magnetic field of stator/armature and the physical motion of the rotor/field.

In this paper, the relationship between the homopolar flux generated by a statically eccentric rotor and the unbalanced magnetic pull in two-pole induction motors is considered. We will show that due to this kind of eccentricity, a homopolar flux is generated having the supply frequency, yielding a vibrational component of the unbalanced magnetic pull with the double supply frequency.

PM Brushless Rotor Claw Pole Motor with FEM

and not easy to manufacture. In [7], a brushless claw-pole double-rotor machine is proposed. The claw poles are separated from the stator and fixed on the outer rotor which is made of nonmagnetic and nonconductive material. PM segments are mounted on the inner magnetic rotor. The toroidal winding is enveloped by a U-shaped stator core.

With τ the pole pitch, the same in the stator and rotor, the claw-pole span in the middle of stator stack, α c τ, is the main design variable for claw poles. The additional geometrical variables are (Figure 6) ϕ c, W 1,W 2, d c, and W c. In general, the pole angle α c = 0.45 to 0.6 and the claw angle is ϕ c = 10 to 20°.

Figure (2) shows a consequent pole design which eliminates the extra cost of thicker magnets because only half the number of magnets are used. In general the lower the motor speed the greater the number of poles and the higher the speed the fewer number of poles are used. The actual rotor design can have an effect on the pole count selection.

The stator teeth on the 8-poles correspond to the 48-rotor teeth, except for missing teeth in the space between the poles. Thus, one pole of the rotor, say the south pole, may align with the stator in 48 distinct positions. However, the teeth of the south pole are offset from the north teeth by half a tooth. Therefore, the rotor may align with ...
