摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to protect the temperature of a motor in all conditions only by measuring the temperature of a brush, since a condition may arise that a high output is required in a short time in a vehicle drive unit, while the brush often becomes highest in temperature when the operation of the brush is continued or repeated. SOLUTION: A brush motor for the vehicle drive unit is configured such that either of a front wheel or a rear wheel of a vehicle is driven by an engine, and the other is driven by a motor. The brush motor comprises the brush that feeds power to a rotor of the brush motor for the vehicle drive unit, and a brush holder that connects power from the outside to the brush via a power line. A temperature sensor for measuring the temperature of the motor is installed to the brush holder. The brush motor also comprises a first overtemperature protecting logic that restricts a motor input by combining an energizing current value and an energizing time, and a second overtemperature protecting logic that restricts the motor input by detecting an output signal from the temperature sensor.

摘要： PROBLEM TO BE SOLVED: To omit a wire harness such as a power cable, etc., and improve power loss, in a vehicle driving system of engine/electric motor composite type. SOLUTION: Part 1 of wheels are driven with an engine 3. Wheels 2 other than the wheels driven with the engine 3 are driven with a dynamo-electric machine 4. The dynamo-electric machine 4 is driven as an electric motor for wheel drive to assist an engine drive system when the travel load is as large as that at start or at climbing up a slope. In vehicle drive, there is an operation range where it does not need electric assistant drive such as the time of low/middle load travel or deceleration. At this time when the assistance is needless, the dynamo-electric machine is functioned as a generator so as to convert the mechanical energy from the wheels into electrical energy. The dynamo-electric machine 4, an inverter 7, a capacitor 11, and a controller 18 are unitized integrally, and the unit is attached to a differential gear 5. COPYRIGHT: (C)2005,JPO&NCIPI
