In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Stepper motors are increasingly important for positioning tasks in automated systems due to their compact size, cost ...

This project is comprise of the simulation of PMDC motor method in Matlab and Simulink. In this project I have observed that how the response of PMDC changes with the change of inputs and the ...

Much has been written about the process of selecting motors for applications in motion control. Motor selection can be complicated. The decisions to be made include whether to employ brushless or ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Our objective in specifying motors for HVACR equipment is to start and run the driven equipment under all operating conditions reliably and with reasonable life expectancy. The manufacturer of the ...

How many times have you heard that a crankshaft, connecting rod, or even forged piston is good for 13 psi of boost? On the surface, this seems reasonable, but the reality is that boost is far from ...
