A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

What Is a Brushless Motor? A brushless motor is a type of electric motor that works without brushes touching the rotor. Compared to traditional brushed motors, brushless motors last longer and are ...

There are trade-offs between brushed and brushless motors, considering factors such as maintenance, efficiency and upfront costs, Control Design writes. For automation engineers, the evolving ...

Not all motors provide the same benefit. Discover the differences between the two primary DC motor technologies in this comprehensive white paper. The goal is for our readers to gain a better ...

A motor — or a generator — requires some normal magnets and some electromagnets. The usual arrangement is to have a brushed commutator that both powers the electromagnets and switches their polarity ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

There are many products with built-in motors around us, such as air conditioners, vacuum cleaners, and electric fans. As robots, drones, and electric vehicles, which are expected to make a big change ...

With the appropriate driver IC and microcontroller, designers can exploit the brushless motor's declining price, smaller size, lighter weight, and minimal maintenance. As recently as two years ago, ...

When choosing a modern power tool, there are many factors to consider before buying. The power source, brand, and price are arguably the most important, but there's one more key distinction to make: ...

In recent years, there has been a move toward using higher-efficiency brushless DC (BLDC) motors in many markets and applications. Many applications are using (or could be using) these motors to ...

Hard drives work by spinning platters full of magnetized data while a read/write head very quickly harvests or changes bits as needed. Older (or perhaps cheaper) drives spin at 5400 RPM, better drives ...
