A pedal-electric (pedelec) bike uses a special sensor to synchronize power from an electric motor with that of human pedaling for a smooth, power-assisted ride. The bracketâ s sensor monitors torque ...

Two e-bikes can both say “500W” (or “750W”) on the spec sheet and still feel completely different on hills, at takeoff, and even at cruising speed. That’s because motor watts are only one piece of the ...

Step motors provide accurate position control without the need for feedback, traditionally in open-loop control schemes. A stepper motor’s shaft normally makes discrete angular movements of ...

The name of the game is acceleration at the wheels. Not motor torque. It’s common practice for EV producers to report the torque of the car’s electric motor. But Peter Rawlinson, Lucid’s chief ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

Most known for their versatility, electric motors have revolutionised the way we view the core definition of power, qualifying it as effective energy expenditure concerning work done over time. Among ...

The Hummer EV is shaping up to be an electric off-road supertruck, with useful trail tools like Extract mode and Crab mode. On the road―or paved track—the star is something else: WTF mode. That’s ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

Choosing motor power is one of the most confusing parts of buying an e-bike. Some riders are told they need 1000W. Others are ...

With the electric vehicle (EV) market heating up and due to become ever hotter, there’s a lot of focus on the key components that go into this major evolution of transportation technologies. Batteries ...

This application note discusses the advantages and benefits in using a BLDC motor to drive a DC brushed motor. For a BLDC controller that uses hall effect devices, there are six steps in the ...
