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, ...

Here is a simple method for estimating the actual load on an electric motor without special equipment. But first, a word of caution: Some applications (e.g., a large forced draft fan) require more ...

Recent studies indicate the level of knowledge and implementation of motor system energy-efficiency measures is low. A plethora of information on motor system design, best practices, purchasing, and ...

Blindly assuming the dynamic peak torques listed on servomotor data sheets for a design almost always results in over-sized, inappropriately expensive gearboxes. A motor’s acceleration peak torque is ...

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 ...

Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power ...
