Patent number: 10553330Abstract: Provided is an in-wheel motor power cable in which a cross-sectional area of a conductor portion can be sufficiently assured for allowing large current to pass therethrough while avoiding excessively large maximum diameter of the cable. The power cable includes a conductor portion; an insulator configured to cover an outer circumference of the conductor portion; a hollow shield wire configured to cover an outer circumference of the insulator; and a sheath configured to cover an outer circumference of the shield wire. The conductor portion comprises a composite strand obtained by stranding a plurality of wire strands each of which is a strand of a plurality of filaments with no insulating layer, each filament being a tin-plated soft copper wire. The insulator is a soft fluororesin, and the shield wire is a braided copper-foiled yarn cable.Type: GrantFiled: April 12, 2019Date of Patent: February 4, 2020Assignee: NTN CORPORATIONInventors: Naoyuki Uchiyama, Akio Nakajima

Patent number: 9688161Abstract: A slip control device for an electric vehicle which accurately determines slippage occurrence with only a rotation angle sensor for motor rotation control and perform rapid control to eliminate the slippage, is provided. A threshold calculation module (21) calculates a normal angular acceleration of a motor depending on a manipulation amount of an accelerator to obtain a threshold, and an angular acceleration calculator (22) differentiates a detection value from a rotation angle sensor (3a) twice to calculate an angular acceleration. A slip determination (23) determines whether a drive wheel (7) has slipped, and a torque limitation (25) limits a torque when a slippage has occurred. The determination (23) determines the angular acceleration and a threshold. The determination (23) counts a number of consecutive times it is determined that the threshold is exceeded, and determines that a slippage has occurred, if the number of consecutive times has reached a set value.Type: GrantFiled: December 22, 2015Date of Patent: June 27, 2017Assignee: NTN CORPORATIONInventors: Yingjie Zhang, Koichi Okada, Naoyuki Uchiyama
