I recently ran into an interesting dilemma while running tests on TI’s new InstaSPIN™-FOC sensorless motor control software. “How do you define motor torque?” On the surface, this sounds like an easy ...

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 ...

All the motors produce either interaction torque, reluctance torque or a combination of both. The second article in this series discussed the underlying principles common to all motors. As we have ...

Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

The McLaren P1 arrived at a moment when “hybrid” still sounded like a synonym for “Prius,” yet it treated electricity as ...

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 LS engine remains the darling of the performance world, but does that mean all LS owners are looking for the same thing when it comes time for upgrades? Obviously not, or every LS story would be ...

I pitted the DJI Avinox M1 against Bosch's Performance Line CX-R, and found there’s more to a motor than outright power and torque ...

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 ...

Myriad applications require custom torque motors — including hard-machining table drives, mirror millers, and measuring and grinding machines. In fact, machine builders for these applications are now ...

Salvaging a beefy motor is one life’s greatest pleasures for a hacker, but, when it comes to using it in a new project, the lack of specs and documentation can be frustrating. [The Post Apocalyptic ...
