In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...

The axial flux electric motor pioneers at YASA are at it again. Just three months after sending tremors through the electric motor market with an unofficial world-record power density that absolutely ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

If you’ve spent enough time riding electric bikes, you quickly realize that power is only part of the draw. Another big part ...

Motor control, particularly frequency-controlled drives, is a technology that has advanced quickly in recent years as a result of the widespread use of motors in a variety of applications and the ...

Genius ideas usually are so simple you start to wonder after seeing them: Why did no one think about this before? This is precisely what we felt after seeing what Infinitum Electric has created: a ...

With all of the deserved attention that silicon-carbide- and gallium-nitride-based systems are receiving, it’s easy to overlook a sturdy, less-glamorous “workhorse” power-switching device that’s been ...

Key components of the 1-MW motor. What comprises the 1-MW inverter system? A look at the channel-type heat-exchanger architecture to keep the system cool. Up to a few years ago, “flying cars”—vehicles ...

Like most electronics, ebike motors are subject to fast-paced change and development, whether that’s power increases, reduction in battery size and weight, better integration or simply increased ...
