あつた。 This type of electric motor structure requires a disk, magnet, yoke, etc. on the rotating shaft of the electric motor, and the assembly cost is also high. An electric motor is shown in which a braking force is applied by generating eddy current using a rotor magnet. However, in these configurations, the magnet on the rotor side is used both as a driving force member for driving the electric motor and as an eddy current generating member, but the eddy current generating plate placed opposite to this magnet is It is specially made and placed opposite the magnet. JP-A-50-15025 discloses a device in which the magnetic pole also serves as an eddy current generating plate. However, the disadvantage of magnetic poles is that the selection of materials is controlled.

Coils 7a and 7b are fixed to the casing, and a urethane foam 9 impregnated with oil and an oil cap 10 are arranged around the bearing 3 to smooth the rotation of the bearing. I have to. A support plate 12 to which a rotor magnet 11 is fixed is fixed to the rotation shaft 3 so as to rotate integrally with the rotation shaft. Note that 13 indicates a shield plate. The motor cover 14 has a pivot receiving portion 15 on which the terminal end of the rotating shaft 3 is pivoted. The motor cover 14 is fixed to the casing 8 and has a yoke 16 made of magnetic material.

応じて渦電流を発生する。 In the present invention, a magnetic field responsive element (not shown) is disposed near the coils 7a and 7b, and the magnet 11 causes current to flow through the coils 7a and 7b, thereby rotating the rotor magnet 11. However, since the magnetic flux from the rotor magnet 11 crosses the casing 8 while reaching the yoke 16, an eddy current is generated in the casing 8 in accordance with the rotation of the rotor magnet.

３と１体に回転するのでヒステリシス損は発生し
ない。 The eddy current generates a braking force proportional to the rotation of the rotating shaft of the electric motor. Further, since the yoke 16 rotates as one unit with the rotating shaft 3, no hysteresis loss occurs.

The present invention provides a motor that can perform overcurrent braking very effectively by changing the current, and the unit cost and assembly man-hours can be reduced, which has great practical effects.
