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.

(Nanowerk News) Researchers from Toulouse (CEMES) and Ohio University have developed a molecular motor 2 nm in diameter ("Controlled clockwise and anticlockwise rotational switching of a molecular ...

• 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 ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...
