and recently upgraded to a new control system featuring Sprint Electric DC drives to extend the lives of the existing motors, keeping replacement costs down. The Swedish stage design and technology company Visual Act retained most of the original motors and mechanics while providing a much-needed facelift to the stage.
In this paper, Edward Hage, founder of specAmotor.com, an online motor calculation and selection tool, focuses on the overheating of electric motors. Presented here is a calculation
method with which the temperature and heat development of a direct current (DC) motor and a brushless motor can be
predicted accurately.
The ocean is full of secrets. Knowledge
of its movement can help scientists and
researchers predict when there’s going to be a drought in California, excessive rainfall on the East Coast or when crops might not make it through a season in Africa.
Robots are everywhere these days—
