FIG. 4 shows the relationship between the heat treatment temperature and magnetism (coercive force, residual magnetic flux density) in each direction of A, B, and C with respect to the rolling direction of the Fe--Mn semi-hard magnet used in the present invention. The starting voltage is the voltage at which the rotor starts rotating with no load, and the starting torque is the maximum load at which the rotor starts rotating when a 100V voltage is applied.

For the rotors manufactured by the present invention in each punching direction, the starting voltage gradually increases as the coercive force increases, and the starting torque value decreases in the order of B, C, and A, and the maximum starting torque value decreases in the order of B, C, and A. The obtained coercive force level is higher in the order of C, B, and A, and the starting voltage at that time is lower in B and C than in A. The desired characteristics of a Warren type synchronous motor are low starting voltage and high starting torque.Judging from this point, B has the lowest starting voltage and the highest starting torque, followed by C, which has better characteristics than A. It can be seen that it has.

In the present invention, a rotor having shape anisotropy was punched out in different directions was tested, and results were always obtained over several times in which the characteristics of the motor varied depending on the direction. Although this is not theoretically clear, it is thought that this is because the material has magnetic anisotropy, so that the combination of magnetic properties of the central magnetic path section and the annular magnetic path section differs depending on the punching direction. As described above, according to the manufacturing method of the present invention, the magnetic anisotropy of the material and the shape anisotropy of the rotor can be easily and appropriately combined, and the rotor using the conventional isotropic material can be easily and appropriately combined. The various characteristics of the electric motor, particularly the starting torque and starting voltage, can be improved.
