The driver is a key factor in determining a motor’s stall performance. Temperature can affect the stall torque of brushless DC motors. Tolerances on the motor parameters can significantly impact the ...

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 ...

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, ...

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 ...

Automakers are always looking for an edge over the competition. Any spec-sheet advantage, no matter how insignificant, is fair game. Engine output is often something they brag about. One vehicle may ...

Forbes contributors publish independent expert analyses and insights. William covers motorbikes, E-bikes, cars, trucks and mobility tech. With the electric vehicle (EV) market heating up and due to ...

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 ...

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.

In the current market, it is common to see new diesel trucks putting out over 1,000 lb-ft of torque from the factory. That's just in the consumer space. When it comes to heavy-duty industrial ...

The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear ...
