Mechanical

The drive or drive train transfers the mechanical power from the motor to the driven equipment. The efficiency of drive trains can vary between 50 and 99 percent. The type of drive train used for a given application can have a greater effect on overall system efficiency than motor efficiency itself.

The choice of transmission type depends on factors including: desired speed ratio, horsepower, physical layout, and load type. The major categories include direct shaft couplings, gearboxes, chains, and belts.

The type and size of drive selected is important because it determines the final speed at which your equipment runs. The drive must be sized to fit the motor and driven equipment; and it must be strong enough to drive the load without failing.
