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.

Electric motors, both ac and dc types, come in many shapes and sizes. Some are standardized versions for general-purpose applications. Others are intended for specific tasks. In any case, motors ...

TMK line of torque motors from ETEL has 30% more torque (on average) and top speed has been increased by a factor of 3.5 compared to the design of traditional torque motors The TMK line of torque ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

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 ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

Brushless DC (BLDC) motors offer many operating attributes in performance and controllability, but they may require a position (rotation) sensor such as an encoder, resolver, or Hall-effect device to ...

We’ve been intrigued by Orbis’ many different swings at providing in-wheel motors that add little or no un-sprung weight ever since company founder Marcus Hays brought us a PHEV Civic Type R with an ...
