An electric motor () includes a stationary shaft-shaped central portion () extending through respective central portions of an inner rotor (), an outer rotor (), and a stator (), and a cooling structure () provided using the interiors of the stator and the shaft-shaped central portion. The motor can be used as an in-wheel motor for directly driving each wheel of the motor vehicle.

Electric motor with cooling structure

An electric motor () is an in-wheel motor. The motor () includes an outer rotor, (), an inner rotor (), a stator (), and a shaft-shaped central portion (). The outer rotor includes a magnet () and is disposed closely to a load. The inner rotor includes a magnet () and is disposed away from the load. The stator is disposed between the outer rotor and the inner rotor, and includes a stator coil. The shaft-shaped central portion extends completely through respective central portions of the outer rotor, the inner rotor and the stator. The shaft-shaped central portion defines a stationary structure. A power supply system () is provided using interiors of the stator () and the shaft shaped central portion ().

Electric motor

In a gas turbine power generation system having a gas turbine engine and a generator connected to the engine, maintenance ease is enhanced by forming the housing to have openable maintenance faces at two of its faces. Installation space is reduced and a compact configuration is achieved by providing a partition that divides the interior space of the housing into two regions into an upper bay and a lower bay, mounting the engine in the upper bay and mounting air intake duct in the lower bay at a location directly under the engine. Noise is reduced by using a partition to define two separate spaces (bays) and mounting the engine and the air intake duct in the upper and lower bays. Noise is also reduced by preventing engine rotation noise from escaping to the outside through the air intake duct. Moreover, it achieves a reduction in the amount of dedicated space required by constituting the air intake duct of a duct section having an air inlet at a plane coincident with that of the maintenance opening and a filter-housing section for removably housing an air filter, thereby enabling a common space to be utilized for that required in front of the maintenance opening and the air inlet.
