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.

Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Achieving a similar reversal of direction of rotation in artificial molecular motors presents a ...

Inverted Quadcopter? That generally means a crash is soon to follow. Not so for a new crop of quadcopter fliers. These new quadcopters are capable of sustained inverted flight. We’ve seen inverted ...
