S801+ vs S811+ Eaton Soft Starters

A Soft Starter is a device that provides an alternative startup method to a typical AC motor with fewer power requirements at start-up. It reduces the amount of drawn inrush current and limits the motor starting torque; this helps reduce potentially damaging mechanical and electrical shocks on the motor system. When a soft starter is added to a motor’s circuit, it continuously regulates the motor’s supply voltage during the start-up phase. This means that the…

Torque Conversion Calculator: What is Torque and how is it Calculated?

Torque Conversion Calculator Newton-meters Foot-pounds Inch-pounds Newton-meters Foot-pounds Inch-pounds What is Torque?   Torque is a measure of the force which can make an object rotate about an axis. In linear kinematics, the force causes an object to accelerate linearly, similarly, torque is what causes an object to acquire an angular acceleration. It’s a vector quantity, meaning it has both magnitude and direction. The direction of the torque vector depends on the direction of force acting…
