A 120-V motor has mechanical power output of 2.50 hp. It is 90.0% efficient in converting power that it takes in by electrical transmission into mechanical power. (a) Find the current in the motor. (b) Find the energy delivered to the motor...
Pmot = mechanical power required at the motor shaft, HP, and PRHP = polished rod power required at the surface, HP. For the estimation of the pumping unit's overall mechanical efficiency, Gipson and Swaim [78] present the correlation shown in Fig. 4.44. The curves, valid for new and wo...

The Panama Canal linkage permits the gate to be uniformly accelerated from rest to the midpoint of its travel, than uniformly decelerated through the remainder of its travel, thus eliminating the need for motor speed control. This was an advantage before advances in motor speed control. This ad...
The difficulty of feature extraction and the small sample size are two challenges in the field of mechanical fault diagnosis for a long time. Here we propose an intelligent mechanical fault diagnosis method for scenario with small sample datasets. This m
The polygonal wear of railway wheels often results in impacting contact at wheel/rail interface and consistent shocks on train unsprung parts (such as axlebox, wheel axle, gear pair, motor cover), especially when the high-order components predominates on the non-circular wheels. In this work, ...

From the system of Park’s equations, [5], as well as from formula (2) it follows that the coupling between the electric and the mechanical system is non-linear in character, particularly for significantly varying motor rotational speedΩ(t), which leads to very complicated analytical descripti...
A device is useful for holding Electricity, in any place on he formula of Ferro magnetic power. The device is an electric power generation. The No. 28 Ferro Magnets are in a Circular Manner are arranged and out of 48 magnets in 4 ways with 12+12 Ferro magnets are arranged in opposite ...
In level mode the Tram cruises the rails under the power of its wind-up rubber band motor. In incline mode the Tram simply employs the power of gravity along with its gear-drive transmission to gracefully scale down tracks. The Tram even has a hidden box for carrying messages to a ...
