    摘要: In exemplary implementations, a bicycle has “power pedaling”, in which a rider's pedaling efforts are augmented by an electric motor. The rider can control the motor simply by pedaling. It is desirable that the motor torque not exceed the rider torque; otherwise the motor overpowers the rider. A radial flexure is part of the drivetrain that transmits torque from the rider to the back wheel. One part of the flexure is connected to the back wheel casing; another part of the flexure is connected to the freewheel. If motor velocity exceeds rider velocity, this causes the flexure to elastically deform. Two sensors measure the deformation, which is equal to the difference between the angular displacements of the casing and freewheel, respectively. A PD controller seeks to make this difference equal to zero, by controlling voltage levels in the motor (and thus controlling the torque contributed by the motor).

    摘要: The present invention discloses that the output end of the bidirectional unequal speed electric motor being particularly used to provide bidirectional rotating input is transmitted to the input end of bidirectional same or different speed change ratio constant directional output transmission device to further provide constant directional rotating output for driving the rotating load, wherein the user can operatively control the driving input direction thereby allowing the bidirectional same or different speed change ratio output transmission device having different speed change ratio to provide constant directional different speed change ratio rotating output in different driving input direction.

    摘要: An electric actuator for varying the position of a valve stem comprises an output shaft adapted to be coupled to the valve stem. The output shaft is selectively rotated, between limit positions defined by a pair of electrical limit switches cooperating with cams carried by the output shaft, through the agency of a motor module comprising one or more electric motors and an associated gear box having an output pinion in drive engagement with an output gear coupled to the output shaft. The output gear includes two sets of concentric teeth disposed in spaced relation to one another, and adapted to be engaged individually by the motor module pinion, for driving the output shaft at different torques and speeds in dependence upon which set of output gear teeth is engaged by the pinion. The motor module can be mounted in either of two different positions to cause its pinion to engage one or the other of the output gear teeth sets. The output pinion is preferably located at an eccentric position relative to the motor module so that pinion engagement can be shifted from one to the other of the gear teeth sets by a 180* reversal in the motor module mounting position.
