Geothermal heat pumps (GHPs) have been around for a long time, but recent technological advances have propelled these systems into a new sphere of efficiency and comfort, said Doug Dougherty, ...

First note - I am a completely new to water cooling, this is the first build I've done. With GPU prices the way they are, I decided to try for an overclock vs a new GPU. Things are working well, and I ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

A1000 variable speed drive has a calculated design life twice as long as previous generations. Compatibility with interior and surface permanent magnet motors produces up to 200 percent torque with or ...

The MDrive34Plus2 Speed Control combines a motor, driver, and encoder, and includes a programmable digital oscillator for accurate, variable-speed control. The device uses a NEMA-Size-34 brushless ...
