Patent number: 8176799Abstract: The sensor holder has an annular portion that holds the sensors. A holding ring that is securely fitted in an inner peripheral surface of a cylinder portion constituting a cover made of metal in terms of a large tight fit is embedded in an intermediate portion of this annular portion in the axial direction. A portion of a folded portion of the holding ring in the axial direction is set in a just center position between axial positions of sensing portions of both sensors. According to this configuration, the above problem is solved by preventing such a situation that the thermal expansion or the thermal contraction yields a phase difference between the output signals of both sensors.Type: GrantFiled: May 23, 2008Date of Patent: May 15, 2012Assignee: NSK Ltd.Inventors: Minoru Kubokawa, Masayuki Maruyama

Patent number: 7835156Abstract: In a power drive unit having power modules (three-phase inverter circuits) connected to a control circuit board, bus bars extending from the power modules and a current sensor each installed near the bus bars and including a sensing element that detects currents outputted from the bus bars, there are provided a sensor board on which the sensing element is mounted, and lead pins each connecting the sensor board to the control circuit board and having a bowed shape whose one end is connected to the sensor board and other end once extends away from the circuit board and then turns back toward the circuit board. With this, the circuit board and current sensors can be connected through the lead pins without increasing the distance therebetween and stress produced in the lead pins can be alleviated, thereby enabling the unit to be minimized in size and utilized in a harsh service environment.Type: GrantFiled: September 8, 2005Date of Patent: November 16, 2010Assignees: Keihin Corporation, Honda Motor Co., Ltd.Inventors: Minoru Kubokawa, Takeshi Nakamura, Takaaki Iijima
