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 ...

Drivers shopping for an electric vehicle in 2026 routinely encounter the claim that an electric motor turns about 90% of its ...

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 ...

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, ...

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 ...

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 ...

Unexpected motor failures can disrupt industrial operations, increase maintenance expenses, and reduce equipment efficiency ...

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 ...

The manufacturing world is going through one of its biggest shifts in decades. Factories that once depended heavily on manual ...

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.
