A washing machine appliance includes a wash basket rotatably mounted within a wash tub for receiving of a load of articles for washing. A motor assembly is operably coupled to the wash basket and an agitation element for selectively rotating the wash basket and the agitation element and includes a drive motor having a motor shaft defining an axial direction, a transmission assembly operably coupled to the wash basket for transmitting torque from the motor shaft to the wash basket and the agitation element and the agitation element, and a cooling fan mechanically coupled to the motor shaft for urging a flow of air as the drive motor rotates the motor shaft, the cooling fan comprising a plurality of blades, wherein the plurality of blades have a geometry that varies along the axial direction to follow a contour of an external surface of the drive motor.

An actuation system and method of operation for moving a closure panel in one of a normal drive state and a back drive state are provided. The actuation system includes a mechanical coupling for moving the closure panel. A motor with a shaft is directly and operably connected to the mechanical coupling to directly move the mechanical coupling. A sensor detects movement of the closure panel and couples to a controller connected to the motor. The controller moves the closure panel with the motor based on a detected motor movement command in the normal drive mode. The controller also detects movement of the closure panel using the at least one sensor and selectively brakes the movement of the closure panel based on the movement detected in the back drive state.

This electrostatic power circuit purpose is to build-up a large amount of powerful electrostatic energy. It has a high direct-current voltage generator acting as an electrostatic energy provider in the form of electric charges, next is an electrostatic generator and its electric motor acting as an electrostatic energy amplifier, and last is an electrostatic motor acting as an electrostatic energy convertor, converting electrostatic energy to mechanical energy. The electrostatic power circuit is a major part of a practical electrostatic power system.

A differential includes a drive rotating body rotatable about a rotation axis, a planetary rotating body that is rotatable and is revolvable about the rotation axis, and a driven rotating body rotatable about the rotation axis. The planetary rotating body is made to mesh with each of the drive rotating body and the driven rotating body, so that a first speed reducer is constituted between the planetary rotating body and the drive rotating body and so that a second speed reducer is constituted between the planetary rotating body and the driven rotating body. The planetary rotating body is driven by an electric motor, and the drive rotating body is driven by a driving force from an engine. The intake camshaft is provided on the driven rotating body, and the exhaust camshaft is provided on the drive rotating body.

An actuation assembly includes a drive mechanism that has an array of magnetic members moveable along an axis, and a gear train that has an input and an output. The drive mechanism causes the input to move in response to generating an electromagnetic field that interacts with at least one of the array of magnetic members.

A laundry appliance includes a drum rotationally positioned within a structural cabinet. An impeller is rotationally positioned within the drum. The impeller is selectively and independently operable with respect to the drum. A binary motor has a first motor and a second motor disposed within a common housing. A first drive belt extends between the first motor and the drum. A second drive belt extends between the second motor and the impeller. The first and second motors engage the first and second drive belts on a belt side of the common housing.

An endless-track traveling apparatus includes a casing, pulleys having axes arranged in parallel in the casing, a motor for driving the pulleys, and an endless track wound on outer circumferential surface portions of the pulleys to rotate together with the pulleys and move on a traveling target. The endless-track traveling apparatus further includes: a plate-shaped member disposed in contact with the endless track and opposed to the traveling target in a space surrounded by the endless track, and fitted in the casing; a magnet fixed in the casing to attract the traveling target; and an elastic member having one end in contact with an inside of the casing and another end in contact with the plate-shaped member, and urging the plate-shaped member in such a direction as to press the plate-shaped member against the endless track.
