Description of the Related Art Conventionally, although there are many demands for electric drive vehicles due to advantages such as low noise and no exhaust gas, acceleration at the time of starting, that is, instantaneous generated torque is low, so that there is a problem in rapid startability. Therefore, the applicant first invented and succeeded in an electric drive type vehicle having a structure in which magnets are attached to wheels of a non-magnetic material at equal intervals on the circumference, and several electromagnets are arranged in a non-rotating vehicle body. . However, under high-speed operating conditions, the number of rotating magnets passing through one electromagnet increases per hour, which shortens the current switching time to the electromagnet, especially the self-inductance that occurs at the moment when the current is turned on and off. And the time constant of the electromagnet circuit becomes a problem.

できる。In view of the above points, the present invention provides a non-rotating side electromagnet and a corresponding rotating side magnet in a double-row (two-row or three-row, etc.) arc shape (in the case of an electromagnet) or a circle. By arranging the magnets circumferentially and reducing the number of magnets per row, the current switching time can be lengthened, and as a result, the self-induced electromotive force can be suppressed as described below.

Since it is proposed in 45, the details are omitted. The operation of the high rotation speed type electrically driven wheel of the present invention will be described. As an example, as shown in FIGS. 1 and 2, the magnets of the rotating wheel are arranged in a two-row or three-row circumferential shape, and an electromagnet corresponding thereto is arranged. If the output torque is equivalent to that in the case of a single row by using two rows or three rows, the number of magnets per row is one row.
Since it can be reduced to about ½ or ⅓, the rise time dt of the current can be increased per electromagnet at the same rotation speed as the single row, and the self-induced electromotive force V of the following equation can be kept low. be able to. Climbing time), that is, self-induced electromotive force Vm equivalent to that of a single train
If you allow up to ax, double the number of single rows, 3 Based on this control, it is possible to improve efficiency, reduce rotation fluctuation, and obtain stable rotation. Needless to say, the electromagnet is designed optimally including other conditions in order to reduce the self-inductance L, the time constant, etc., and the self-induced electromotive force is reduced by using the rotating wheel according to the present invention. High rotation speed is possible.

回転変動は小さく安定した回転となり、しかも１列当り

る。As is apparent from the above description, the electric drive wheel of the present invention is as shown in FIGS. The second row is located where the angle is added. Since the total number is the same as that of a single row, the rotation fluctuation is small and the rotation is stable even at low rotation speeds. Since the number of magnets is small, the self-induced electromotive force per electromagnet can be kept low and high rotation speed can be achieved, which not only solves the problem of rapid startability of conventional electric drive vehicles, but also has low rotation speed. It can be said that it is possible to design a vehicle that has stable rotation from the range to the high rotation speed range.
