In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...

The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear ...

DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

Systems that have controlled parameters and closed-loop feedback mechanisms are generally more robust and less susceptible to failure. For example, vehicle engines regularly use temperature sensors ...
