Torque motors are frameless kit motors consisting of a permanent-magnet rotor and laminated stator. A bridge keeps the rotor and stator aligned while the torque motor is assembled. Torque motors come ...

A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180°. But they are widely used to operate ...

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 ...

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 ...

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 ...

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 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 ...
