With alternating current, electrons regularly reverse direction. The relevance of AC in the world of EVs is that all batteries require direct current (DC), in which electrons always flow in the same ...

Electric vehicles function in fundamentally different ways than traditional cars. Internal combustion engines have loads of moving parts, and while EVs have their own complexities, they’re much more ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

With the internal combustion engine (ICE) being a staple of multiple forms of transportation since the late 19th century, most people are at least somewhat familiar with how an engine works: fuel and ...

Brushless DC (BLDC) motors transform electrical power into mechanical power. However, there’s no such thing as a perfect motor; there are always losses in the transformation. The three main types of ...

We’ve long-admired internal combustion engines for their power density pursuits. Extremely high horsepower-to-liter ratios for naturally aspirated cars like the Honda S2000, Ferrari 458 Speciale, or, ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

Electric motors truly are the driving force behind electric vehicles (EVs). In addition to the batteries and power electronics, the electric motor is a critical component within the drivetrain.

Electric marine propulsion is rapidly advancing in market share while providing a fun and unique boating experience not available from internal combustion power. You might be surprised to learn that ...

A technology pioneered by Benjamin Franklin is being revived to build more efficient electric motors, an effort in its nascent stage that has the potential to be massive. A handful of scientists and ...

Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.

Laws are becoming more stringent for internal combustion engines. Whether they concern a car’s emissions, fuel consumption, or fire safety, the day of the internal combustion engine is coming to a ...
