DC motors may not be the wave of the future, but they certainly have a secure place in today’s workplace (see DC Isn’t Dead). Therefore, it’s worthwhile for electrical professionals to take a look at ...

It ‘s worth noting that back EMF plays a critical role as a natural current limiter during normal motor operation. When motor ...

[Robert Murray-Smith] doesn’t like the price of inverters to convert DC to AC. That led him to build a dynamotor, or what is sometimes called a motor-generator set. These devices are just DC motors ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

Figure 8 depicts an electrical vehicle climbing an incline moving forward (top) or in reverse (bottom). When the vehicle rolls downhill it will turn the motor pressed by the force of gravity so the ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

Engineering efforts to simulate radial-flux machines concentrate on inherently 2D problems. Most of the 2D FEA software is good for "quick-and-easy" solutions demanded by shorter design schedules.

In this insightful and educational video, learn how to make a mini generator 220v using a DC motor. This step-by-step guide will take you through the process of transforming a simple DC motor into a ...
