A simple displacement diagram illustrates the follower motion at a constant velocity rise followed by a similar return with a dwell in between as depicted in figure 2. [4] The rise is the motion of the follower away from the cam center, dwell is the motion where the follower is at rest, and return is the motion of the follower toward the cam ...
[1] A variation of the cam engine, the swashplate engine (also the closely related wobble-plate engine), was briefly popular. [2] Cam engines are generally thought of as internal combustion engines, although they have also been used as hydraulic and pneumatic motors. Hydraulic motors, particularly the swashplate form, are widely and ...
A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
The motor speed varies as a non-linear function of load torque and armature current; current is common to both the stator and rotor yielding current squared (I^2) behavior [citation needed]. A series motor has very high starting torque and is commonly used for starting high inertia loads, such as trains, elevators or hoists. [2]
Another form is a solid one-piece metal bushing with a figure eight groove channel on the inner diameter that is filled with graphite. A similar bearing replaces the figure eight groove with holes plugged with graphite. This lubricates the bearing inside and out. [36] The last form is a plastic bearing, which has the lubricant molded into the ...
It is a main part of their patent on flying. [1] Unlike modern control surfaces, they used wing warping. [2] In an attempt to circumvent the Wright patent, Glenn Curtiss made hinged control surfaces, the same type of concept first patented some four decades earlier in the United Kingdom. Hinged control surfaces have the advantage of not causing ...
Some safety videos are made using three-dimensional graphics. [2] Other videos were made to be humorous, or feature celebrities, or were based on popular movies. Many safety videos were uploaded to YouTube. [3] [4] The flight attendant featured in a Delta Air Lines video from 2008 has become an internet celebrity known as Deltalina.
