摘要： PROBLEM TO BE SOLVED: To prevent noise entering from a main circuit cable, and facilitate connection work. SOLUTION: In a terminal box 4, a terminal block 10A is stored. In this terminal block 10A, terminals 12A, 12B, 12C are integrally formed by an epoxy resin-made terminal base 10a. In each terminal 12A, 13B, 12C, L-shaped terminals of long and short bottom parts are progressively provided as connection parts. Of the connection parts, the connection part of the terminal 12B to which a core wire 7v of the V phase is connected is higher than that of the terminal 12A of the U phase. Further, the connection part of the terminal 12C of the W phase is higher than the connection art of the V phase. Each core wire 7u, 7v, 7w is connected successively in order of U phase, V phase, W phase, so as to prevent crossing of the core wires inside the terminal box, and hence connection work is facilitated.

摘要： PURPOSE: To downsize a device, and enhance braking performance by arranging a large diameter frame to which a permanent magnet is opposed on the outer peripheral side of a stator of an electric motor arranged on a wheel shaft, and discharging a cooling wind from a cooling wind introducing port to a brake disc fixed to a small diameter frame on its shaft directional tip through a wind discharge port of the large diameter frame. CONSTITUTION: A rotor 14 is arranged on a wheel shaft 11 so as to approach one wheel 12b side, and a cylindrical frame 15 is composed of a large diameter part 21 as a large diameter frame and a small diameter part 22 as a small diameter frame continuously arranged in the large diameter part 21. A permanent magnet 16 is arranged in the large diameter part 21, and a brake disc 23 is fixed to the small diameter part 22. A cooling wind introducing port 24 is arranged in the wheel shaft 11, and a wind discharge port 25 is arranged in one end part of the large diameter part 21. The wind discharge port 25 which discharges a cooling wind introduced from the cooling wind introducing port 24 to a side surface of the brake disc 23 and cools this, is arranged in a recessed part 27 of the large diameter part 21. Since this brake disc 23 is cooled by a cooling wind from the cooling wind discharge port 25, heat capacity is increased, and a device can be downsized.

摘要： PURPOSE:To increase a braking force without increasing an outward form by a constitution wherein a soft magnetic material is filled into every gap between a plurality of frames. CONSTITUTION:One-pair of grooves 8 whose cross section is semi-circular are formed on adjacent opposite faces of frames 5 for a brake so as to be parallel in the front and rear direction. A filling material in which solid grease has been mixed with an iron powder is injected into the grooves 8. A foamed material by a rubber material is inserted in advance into the outer circumference. Then, a magnetic flux which is generated by applying a current to exciting coils 1 is passed through a magnetic path which is formed between the adjacent frames 5 and individual magnetic-pole iron cores 2 and a rail at the lower part of brake shoes 3 at lower ends of the magnetic-pole iron cores 2. However, the magnetic flux which is passed through the magnetic path can be increased sharply because the filling material is interposed in gaps formed between the adjacent frames 5 so as to increase permeability as compared with the air. As a result, a braking force can be increased without increasing an outward form.
