... ounces per root watt (Kt/Sqrt[Rm]) which is a very useful measure because it describes a motors ability to produce torque as a function of heat. As you can see, the heat dissipated goes up with the square of the torque. This power produced is solely from I^2R loss in the copper winding and does not ...

... are some factors to consider. The force on the projectile increases as the gradient of the square of the magnetic field produced by the current in the coil. The strength of the magnetic field, and therefore the gradient, increases with the number of ampere-turns. The gradient also changes with the r ...

Friction-plate electromagnetic couplings

Electromagnetic clutches and brakes operate electrically, but transmit torque mechanically. This is why they used to be referred to as electro-mechanical clutches or brakes. Over the years, EM became known as electromagnetic versus electro mechanical, referring more about their actuation method versus physical operation. Since the clutches started becoming popular over 60 years ago, the variety of applications and brake and clutch designs has increased dramatically, but the basic operation remains the same.This article is about the working principles of single face friction plate clutches and brakes. In this article, clutches and brakes are referred to as (mechanical) couplings.
