Using a rotation tester when installing a motor saves time and prevents problems such as driving the load backward. In some cases, you must get the motor rotation correct or massive damage will occur.

The project is designed to drive an induction motor for the required application in forward and reverse directions using wireless technology. For an example, an exhaust fan can be used in both the ...

(Nanowerk News) A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic ...

• Hall-effect sensors used to control dc-electric motors can detect motor rotation direction, and rpm. • Improper inflation of aircraft tires drastically shortens tire life span, leading to premature ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

The ability to control the motors’ speed and rotation is the design key of drones, making the electronic speed control (ESC) module an added value and a fundamental part of a drone. In this article, ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...
