Vacuum degassing is a process used in the purifying of steel
for ball bearings ensuring a very dense and consistent bearing surface. This results in a longer lasting superior bearing.
A multi-speed motor used on loads with torque requirements,
which vary with speed as with some centrifugal pumps and blowers. The horsepower varies as the square of the
speed.
A motor being mounted vertically (shaft up or down) as in many
pump applications.
A vertical motor with a special mounting face conforming to
NEMA design “P” 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 attached. NEMA
requires that motor be able to carry its rated horsepower at nameplate voltage
plus or minus 10% although not necessarily at the rated temperature rise.
Loss encountered across a circuit impedance from power source
to applicable point (motor) caused by the resistance in conductor. Voltage drop across a resistor takes the form
of heat released into the air at the point of resistance.
