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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

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.

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 ...
