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 ...

There are trade-offs between brushed and brushless motors, considering factors such as maintenance, efficiency and upfront costs, Control Design writes. For automation engineers, the evolving ...

This fall, the SMMA Motor & Motion College will offer three motor control courses. Topics to be covered include the Basics of Brushless DC Motors, Basic Motor Theory, Operation and Application, and ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

The wide range of electric motors can be a confusing topic even without considering intelligent motor control. This brief overview is for those who think motors are only divided into two categories: ...

The last 20 years have seen precision amplifiers used for positioning and velocity control make major strides in power output, size, and control features. Applications such as laboratory automation, ...

Sometimes, you have to drive four motors, and you need to do so with a certain level of control. You could throw a lot of parts at the problem, but you don’t necessarily have to. As [Shaun Crampton] ...

In 1960, the large-angle type PM step motor was the most used step motor. This two-phase, bifilar wound PM step motor (top) advanced 45° mechanical with each pulse from the drive, while by 1962 PM ...
