<P>PROBLEM TO BE SOLVED: To provide an unprecedented novel drive motor for a vehicle, capable of performing a field weakening operation in a high speed rotation range with the advantages of small size and light weight, with little wasteful power consumption and low-cost configuration, and independently driving the left and right vehicular drive wheels using a single motor. <P>SOLUTION: This drive motor for the vehicle is configured so that all pole magnets of a first rotor 5a are constituted of N-pole side permanent magnet bodies 53a; all the pole magnets of a second rotor are constituted of S-pole side permanent magnet bodies 53b; respective motor shafts 51a and 51b of the both rotors 5a and 5b are connected by a magnetic body connecting portion 6, while rotating independently from each other; a field coil portion 7 for generating a field magnet that is common in the motor shaft direction between the both rotors 5a and 5b is provided; and a magnet path between a first and second stators 4a and 4b is formed by a magnetic frame 3. Thus, by adjusting the current direction and power volume of the field coil portion 7, the weak field operation can be operated in the high-speed rotation range, and the left and right drive wheels 9a and 9b of the motor shaft 51a and 51b can be driven independently. <P>COPYRIGHT: (C)2007,JPO&INPIT |
