Abstract

An electric motor and a vehicle drive device having the same are provided. The electric motor includes a core unit having plural core assemblies fixed to a case, an annular bus ring attached to the core unit, plural supporting members attached the plural core assemblies, respectively, an attachment member holding a first sensor and fixed to a portion of a terminal accommodating portion such that the first sensor is soaked in an oil stored in the case, and an attachment member holding a second sensor and fixed to a portion of a terminal accommodating portion such that the second sensor is positioned at a second position for measuring a temperature of the coils between adjacent terminal accommodating portions which are not soaked in the oil.

Description

technical field [0001] The present invention relates to an electric motor and a vehicle drive device using the electric motor as a drive source. Background technique [0002] Currently, rotating electrical machines such as electric motors and generators are incorporated into driving devices of hybrid vehicles and electric vehicles. In such a rotating electrical machine, there is a disadvantage in that the temperature rises due to the need for a large current to flow during use, or because it is used near an engine. Therefore, it is important to simultaneously monitor the temperature of the coil and the oil temperature of lubricating and cooling oil with a temperature sensor, and to ensure safety by performing appropriate control such as operating a safety circuit when the temperature rises. [0003] For example, in the technique disclosed in Patent Document 1, a thermistor 50 serving as a temperature sensor is inserted into a temperature detection insertion hole 17 wound in...
