Patent number: 7345383Abstract: A single state detector circuit can quickly detect short-circuit and open-circuit abnormalities of a load controlled by a power transistor. A DC power supply, the load and the power transistor are serially connected with one another, so that a switching terminal voltage of the power transistor is binarized into high and low levels by the state detector. The power transistor is linearly controlled by a constant-current control circuit so as to suppress an excessive current, and power supplied to the power transistor is interrupted by an overheat interruption circuit. Upon occurrence of a short-circuit in the load during generation of an energization command, a switching terminal voltage of the power transistor becomes stabilized at a high level without intermittent operation, which is detected by the state detector. Upon occurrence of an open-circuit during generation of a deenergization command, a low switching terminal voltage is detected by the state detector.Type: GrantFiled: April 21, 2006Date of Patent: March 18, 2008Assignee: Mitsubushi Denki Kabushiki KaishaInventors: Yuji Zushi, Shozo Kanazki

Patent number: 7345384Abstract: In a linear motor, a can has a two-layer structure including an inner can 2 and an outer can 3, and an inner passage 7 formed between an armature winding 9 and the inner can 2 and an outer passage 8 formed between the inner can 2 and the outer can 3 are constituted by each can. Communicating portions 7A and 8A for causing the inner passage 7 and the outer passage 8 to communicate with each other are provided in the vicinity of a refrigerant supply port 5 in each of the cans 2 and 3 in such a manner that a refrigerant supplied from the refrigerant supply port 5 branches into the inner passage 7 and the outer passage 8 and thus flows. Consequently, it is possible to obtain a linear motor armature and a linear motor having a high cooling capability which can prevent the deformation of the can by using a conventional inactive refrigerant to improve the passage for the refrigerant.Type: GrantFiled: November 29, 2002Date of Patent: March 18, 2008Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Shusaku Yoshida, Akio Sakai, Yuji Nitta, Takao Fujii

Patent number: 7345386Abstract: An electric drive unit includes an electric motor for driving a fan. The motor has an electronic control module. An impeller wheel for producing a working air flow is mounted by bearings on an axle of the electric motor. The hub of the impeller wheel has at least one preferably two walls enclosing a cooling space or cooling space portions. At least one cooling surface of a cooling body is in contact with components of the electronic control module and projects into the cooling space. A gap formed between the hub of the impeller wheel and a carrier section communicates with an inner hub space. Holes (43, 322) communicating with the hub inner space are provided in at least one component of the electric drive unit. When the impeller wheel rotes a convection cooling air flow is established between the gap and the holes.Type: GrantFiled: November 27, 2002Date of Patent: March 18, 2008Assignees: Conti Temic microelectronic GmbH, TEMIC Automotive Electric Motors GmbHInventors: Viktor Dano, Hans-Joachim Fach, Ferdinand Friedrich, Matthias Gramann, Reinhard Orthmann, Hermann Pirner, Thomas Schencke, Thomas Susemihl, Wolfgang Thiel, Dietrich Von Knorre

Patent number: 7345387Abstract: An automotive alternator in which a fan rotating together with a rotor to direct air from a suction aperture into a case, blow the air centrifugally, and discharge the air externally through a discharge aperture has a blade including an interposed portion extending axially from an end surface of a pole core between an adjacent pair of claw-shaped magnetic poles. For this reason, cooling of a rotor coil and a stator coil is improved by improving capacity of the fan in a limited space, thereby enabling output to be improved.Type: GrantFiled: August 9, 2004Date of Patent: March 18, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hiroyuki Akita, Keiichiro Oka, Wakaki Miyaji, Toshiaki Kashihara

Patent number: 7345389Abstract: A motor includes a casing and a holder which support a rotation shaft. A concave groove is formed in the holder near the inner periphery of the holder. The concave groove accommodates a positive temperature coefficient thermistor functioning as an overcurrent protection device. A tapered cutout surface is formed on the outer wall of the holder so that the cutout surface is inclined at 45 degrees with respect to a line passing through the rotation shaft and the groove portion of the holder has a maximum length of the holder in its axis direction. A multi-direction input device includes these two motors functioning as driving sources to provide a force feedback to an operation lever. The first and second motors are disposed such that lines passing through their rotation shafts are orthogonal to each other and cutout surfaces are opposed to each other with an intersection of the lines therebetween.Type: GrantFiled: May 19, 2005Date of Patent: March 18, 2008Assignee: Alps Electric Co., Ltd.Inventor: Shigeru Furuki
