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 suppress the increase in loss due to high harmonics and the temperature increase of a permanent magnet and at the same time improve motor efficiency by setting the gap dimension between a stator core and the permanent magnet and the ratio of the opening width of a slot to the width of a core gear part to values within each specific limited range. CONSTITUTION: The gap length between a permanent magnet and a stator core is set to 2.5mm or less and the gear width of the stator core is at least doubled as compared with a slot width to set the magnet temperature increase of the permanent magnet mounted to an outer rotor yoke to 20K or less. On the other hand, the gap length is set to 5mm or less to avoid the increased size of a motor due to the increase in the core length and the slot width of a gear width is set to four times larger than the slot width or less to eliminate the trouble in terms of manufacture of the stator due to the increase in slot depth, thus suppressing the increase in loss due to high harmonics and temperature increase of the permanent magnet and improving the motor efficiency within a range which is reasonable for the slot and an armature coil without increasing the size of the motor.

摘要： PROBLEM TO BE SOLVED: To attain smooth driving at a curve part and high speed stability at a straight section in a vehicle driving controller of right and left wheel independent driving system. SOLUTION: A torque command setting part 11 outputs torque command Trqref corresponding to a train speed V. A right and left wheel speed difference control gain setting part 13 sets a control gain G(s) according to the radius of curvature (r) of an orbit and train speed V, and speed difference correcting torque ΔTrq is calculated from a rotational speed difference (ωrL-ωrR) between right and left wheels respectively using a control gain G(s) given by a right and left wheel speed difference correcting torque calculating part 12. The last torque commands TrqrL, TrqrR are calculated by regulating the right and left wheel speed difference correcting torque ΔTrq to the torque command Trqref in a right and left wheel speed difference correcting part 14, and a left wheel driving motor 16L and a right wheel driving motor 16r drive a left wheel 15L and a right wheel 15R respectively based on the last torque command.

摘要： PURPOSE: To fix permanent magnets without using any screw so that the coming off of the magnets from a cylindrical frame can be prevented by press-fitting fixing members into recessed sections each of which formed between each permanent magnet on the inner peripheral surface of a cylindrical frame, is extended in the axial direction of the frame, and has two or more wedge-like cross sections and grooves each of which is formed at the end section of each permanent magnet on the frame and has a wedge-like cross section. CONSTITUTION: Recessed sections each of which is extended in the axle direction of a railway vehicle and has a wedge-like cross section are formed between rectangular permanent magnets 11a and 11b arranged on and fixed to the internal peripheral surface of a cylindrical frame 10 at prescribed intervals. In addition, grooves each of which is extended in the axle direction of the vehicle and has a wedge-like cross section are formed in the gap sections between the magnets 11a and 11b. Fixing members 14 having shapes matching with those of the recessed sections and grooves are press-fitted into the recessed sections and grooves. Moreover, the angles of retaining slopes 14a and 14b which are formed between the magnets 11a and 11b and the angles of the retaining slopes 10a and 10b of the frame 10 are controlled within the range of 75 deg.-105 deg.. Therefore, the coming off of the magnets 11a and 11b from the frame 10 can be prevented without using any screw even when the frame 10 vibrates.

摘要： PURPOSE:To obtain a readhesion control means which can suppress idling and slip and can maintain adhesion as high as possible by detecting idling or slip in early stage through predicted speed of driving wheel and suppressing inverter output frequency. CONSTITUTION:Rotational frequency of driving wheel is fed to speed operating units 31-34 which then operate shaft speeds 61-64 to be fed to speed predicting units 81-84. The speed predicting units sequentially generates predicted speeds 111-114. Since the shaft speed exceeds (or drops below) the predicted speed upon occurrence of idling(or slip), transition is made to inverter frequency suppression control when the speed difference exceeds a prescribed level. Since torque of an induction motor decreases, inverter output current decreases correspondingly to a level corresponding to the adhesion coefficient at that time and thereby positive readhesion is realized while suppressing torque reduction as low as possible.

摘要： PROBLEM TO BE SOLVED: To enhance a novel control method wherein the detection of the occurrence of slip or slid and the activation of readhesion control are separated from each other.
SOLUTION: When an occurrence of slip or skid of driving wheels increases the circumferential speed V of the driving wheels and the speed difference Vd, or a difference from a reference speed Vm reaches a predetermined threshold value Vs1 at time t1, the occurrence of slip or skid is detected. When the circumferential speed V thereafter further increases and the speed difference Vd from the reference speed Vm reaches a second threshold value Vs2 at time t2, readhesion control is activated. The threshold value Vs2 is determined according to the curve radius of the track on which the relevant vehicle is running. When the curve radius is close to infinity (that is, a straight line), the threshold values are taken as Vs1=Vs2. Then when an occurrence of slip or skid is detected, readhesion control is immediately activated. When the curve radius becomes smaller, Vs2 is made larger than Vs1 and the timing of the activation of readhesion control is delayed.

摘要翻译：要解决的问题：为了增强其中滑动或滑动的发生的检测和再粘合控制的激活彼此分离的新型控制方法。解决方案：当驱动轮的滑动或滑动的发生增加驱动轮的圆周速度V和速度差Vd时，或者与参考速度Vm的差异在时间t1达到预定阈值Vs1时，发生检测到滑动或滑动。当其后的圆周速度V进一步增加，并且在时间t2从参考速度Vm的速度差Vd达到第二阈值Vs2时，再次粘附控制被激活。阈值Vs2根据相关车辆所在的轨道的曲线半径来确定。当曲线半径接近无穷大（即直线）时，阈值取为Vs1 = Vs2。然后当检测到滑动或滑动的发生时，立即激活再粘附控制。当曲线半径变小时，Vs2变得大于Vs1，并且再次粘附控制的激活定时被延迟。版权所有（C）2009，JPO＆INPIT
