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.

To successfully follow a velocity profile, a motor and drive combination must generate enough torque to: accelerate the load inertia at the desired rates, and drive the load torque at the desired ...

Proper evaluation of torque margins across the full motion profile prevents stalling and ensures consistent performance under varying load and speed conditions. Mechanical resonance can cause ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

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 ...

Motor controllers in general and especially closed-loop controllers have come a very long way in the past few years. Control flexibility, adaptability, and strategies that were only dreamed of or very ...
