摘要： PROBLEM TO BE SOLVED: To obtain a strong magitetic attracting force from a magnet type chain belt even when the sizes of the magnets or magnet units used in the chain belt are not increased and to firmly connect the magnet units to each other in a chain-like state by using simple constitutions, and then, to smoothly give the rotational force of a pulley to the chain belt. SOLUTION: Each magnet unit 4 is formed by respectively putting ferromagnetic yokes 5 on both side faces of a permanent magnet 4 in the direction of magnetization and a magnet type chain belt is formed by successively connecting the unit 1 to another unit 1 in a chain-like state by using first and second link plates 2 and 3. In addition, a pulley which gives a rotational force to the magnet type chain belt is formed in a cylindrical shape having no projection on its outer periphery.

摘要： PROBLEM TO BE SOLVED: To operate a brushless motor at a high speed, equal to or above a specified number of revolutions by forming an armature coil from a single conductor, and serially connecting a single conductor positioned in a required pole or phase at a coil end. SOLUTION: The present invention relates to a brushless motor, which is driven at a high speed of 4000 rpm or above by a flip-flop inverter and delivers a favorable performance. In case of 8-pole and 6-phase, a coil in each phase of an armature coil 22 is formed into a wave shape. To move a rotor 10 to the right, the phases of the armature coil 22 are connected, respectively, so that traveling waves in the same direction are produced. In addition, a circular or an elliptic closed or open slot is formed in the stator core, and a single insulated conductor is inserted into the slot to be connected to the armature coil 22. As a result, leakage flux within the slot can be reduced, and further the skin effect at the cross section of the conductor within the slot can be effectively reduced, especially during high-frequency driving. Thus, highly efficient operation is possible.

摘要： PURPOSE: To enable a magnetic belt type transporter to run on a slope of steep inclination by using magnetic wheels, running while being sucked to the upper surface of a rail, as supporting wheels. CONSTITUTION: Magnetic wheels 4 running, while being sucked to the upper surface of a rail 2, as well as supporting a vehicle body 1a are provided on the upper surface of the rail 2. Each of these magnetic wheels 4 is composed of a pair of wheel parts 4a and a permanent magnet 4b arranged between the pair of wheel parts 4a. On the other hand, a magnetic belt 5 for giving a thrust to a vehicle 1 by rotating while being sucked to the side surface of the rail 2 is arranged on the side surface of the rail 2. Since the vehicle body 1a is prevented from its floating up in the horizontal direction by means of a suction force possessed by the magnetic wheels 4, the vehicle body 1a can smoothly run without being separated from the rail 2 even on the slope of steep inclination (e.g. 45 to 90deg.).

摘要： PURPOSE: To insure sufficient length of a magnet against width of a magnet belt so as to enlarge attractive force and intensify combining force between a magnet unit and the belt by inserting a rivet member into the through hole of a yoke, the through hole of the belt, and the through hole of a metal fitting, and striking both ends for riveting. CONSTITUTION: Both ends of a rivet member 11 are crushed, especially one end on the yoke 7 side is deformed along the form of the spot facing hole of a yoke through hole 7a, and hence the head part of the rivet member 11 is not heaped up from the bottom face 7b of yoke. Hereby a magnet 8 of long length can be fixedly secured on the whole bottom face 7b of yoke. Further the rivet member 11 can be arranged on the center side from the end face of a belt 30, and hence resistance to looseness can be enlarged so as to be more safe. Furthermore, a plurality of stepped through holes 30c are arranged on the projection part 30b of the back of belt, a magnet unit 100 is riveted to the belt 30 through metal fittings 10 in the stepped through holes 30c, and resistance to slipping-off of a magnet unit 100 is improved.

摘要： PURPOSE:To exchange and repair a damaged driving unit easily and provide so as to make the magnet belt of the driving unit follow the side face of a rail nicely by detachably and turnably fitting the driving unit for a vehicle traveling along the rail to the bottom of a truck. CONSTITUTION:A driving unit 100 is arranged in a truck 4 traveling along a rail 2 comprising a magnetic body fixed on the ground. A magnet belt 8 is sucked on the side face of the rail 2 by turning and driving a pulley 9 through a speed reducer 11 by a motor 10 so as to turn the driving unit 100. At that time, the driving unit 100 is detachably and turnably fitted to the truck 4 through a pair of joint rods 12a, 12b. Accordingly, only a damaged driving unit 100 can be exchanged and repaired easily when a part of the magnet belt 8, etc., is damaged. The magnet belt 8 can be brought in nice contact with the side face of the rail 2. So as to follow the rail 2.
