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 ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

The Spiroid technology in the design offers a number of performance benefits: Extremely high torque transmission, high stiffness/low deflection with large applied loads, back-drivable (4:1 ratio) & ...

Value is a buzzword in today's economy, but in the world of tools, oftentimes "value" is seen as inferior. Not so with Eastwood's new digital electronic torque-angle wrenches. We used them side by ...

In this 4th article on the ‘Journey of the electrical motor ‘, “we revisit our discussion on the relative angle between the magnetic fields. To achieve a particular torque value, we must maintain a ...

{Editor's note: This article originally appeared as a series of blogs in EE Times. It is replicated here in its entirety for the convenience of the EDN community.} Motors are all around us, and an ...

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, ...

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 ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...

Cam swaps are all the rage and for good reason. Adding an aftermarket cam to an otherwise stock engine can boost output by 40-60 hp (or more) with no other changes (except possibly a valvespring ...
