VACUUM DEGASSED BEARINGS
Vacuum degassing is a process used in the purifying of steel for ball bearings assuring a very dense and consistent bearing surface. This results in a longer-lasting superior bearing.
A multi-speed motor used on loads whose torque requirements vary with speed as in some centrifugal pumps and blowers. The HP varies as the square of the speed.
A motor being mounted vertically (shaft up or down) as in many pump applications.
VERTICAL “P” BASE MOTOR
A vertical motor with a special mounting face conforming to NEMA’s “P” design and with a ring groove on the shaft.
The force that causes a current to flow in an electrical circuit. Analogous to pressure in hydraulics, voltage is often referred to as electrical pressure. The voltage of a motor is usually determined by the supply to which it is being attached. NEMA requires that the motor be able to carry their rated horsepower at nameplate voltage plus or minus 10% although not necessarily at the rated temperature rise.
Loss encountered across a circuit impedance from the power source to applicable point (motor) caused by the resistance in a conductor. The voltage drop across a resistor takes the form of heat released into the air at the point of resistance.
