MOWER DRIVEN BY ELECTRIC MOTORS
In a mower (10) driven by a pair of electric motors (15), a battery (16) for supplying electric power to the electric motors is positioned in a space surrounded by the electric motors and a chute (30) for forwarding grass clippings to a grass collection bag (23). The chute extends rearward with an upward slant, and is bent in side view in such a manner that a lower part has a steeper incline than an upper part thereof.

WORK VEHICLE
A mowing vehicle 1 provided with a traveling machine 10 and a mowing device 20 includes a first image-capturing device 30 and a controlling unit C configured to control the traveling machine 10 to travel autonomously along a boundary line of grass before and after mowing formed by the mowing device 20. The controlling unit C includes a boundary-detecting unit C2 configured to detect the boundary line and a traveling-controlling unit C3 configured to control traveling directions of the traveling machine 10. The boundary-detecting unit C2 is configured to generate intensity distribution information regarding texture information in a predetermined direction by filtering with a Gabor filter on a captured image. The boundary-detecting unit C2 is configured to carry out statistical processing on the intensity distribution information per inspection area divided in plural in a vertical direction so as to detect boundary points and to detect the boundary line from the boundary points per the inspection area.
Apparatus for switching between wye and delta configurations in an electric motor
An electric motor, including a motor assembly having a rotor and a stator, and a switching assembly adapted to switch the motor assembly between a wye configuration, a delta configuration, and a neutral configuration. The switching assembly may include a plurality of actuators configured to move at least two movable contact members so as to select which configuration of the motor assembly is active.

Machine for generating electrical energy
In accordance with one embodiment, a machine for generating electrical energy comprises a housing and a shaft rotatable with respect to the housing. An impeller has blades for rotation with the shaft in response to receipt of material from a chute. A first generator assembly comprises first stator windings associated with the housing and a first magnet affixed to the shaft, such that if the impeller rotates an electromagnetic signal energizes the first stator windings based on the flow of material through the chute.
