THE POWER OF STATIC CLING
C-Motive's motors run on the principle of electrostatic forces, also known as "static cling." This transformative technology stands to change how engineers design the machines that shape and run our lives.
Our motors produce torque by the same principle of rubbing a balloon on a head of hair. The torque produces near-zero heat, just like hair doesn't heat up when charged. Electrostatic torque is produced with voltage and is nearly lossless.
Conventional motors, on the other hand, use the principle of copper coils around steel, which produces torque using current, and current produces heat. Electromagnetic torque always produces heat.
Benjamin Franklin invented the first electrostatic motor in the 18th century, so the fundamental idea isn't new. Many others have also advanced the concept. But those previous motors had very low torque output and were simply impractical. C-Motive is the first team to produce useful levels of torque.
Using "static cling" to create torque means excellent efficiency characteristics at low speeds, where conventional motors are least efficient. It also means that motors no longer require steel, copper or rare earth materials, nor must they have any magnetic properties.
Engineers designing complex systems can now consider electrostatic motors as alternatives to electromagnetic motors and actuators, in addition to pneumatics and hydraulics.
