Motor Information
Service Factor A safety factor to be used when the load temporarily exceeds the nominal horse power rating of a given motor. When used on a motor nameplate, a number which indicates how much above the nameplate rating a motor can be loaded without causing serious degrad	1
Phase Indicates the space relationships of windings and changing values of the recurring cycles of AC voltages and currents. The most common power supplies are either single- or three-phase.	1
Voltage The force that causes a current to flow in an electrical circuit. 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 1% al	115/208-230
HP The power required to drive an air moving device. Horsepower required varies with system conditions.	3/4
Hertz Measure of the frequency or cycles per second.	60
Motor Enclosure The housing or frame of the motor.	n/a
RPM The number of times per minute the shaft of the motor (machine) rotates. This is a function of design and the power supply.	1800
Motor Insulation The class of motor insulation for a given motor. The temperature capabilities of each insulation class is defined as being the maximum temperature at which the insulation can be operated to yield an average life of 2, hours (A = 15?C, B = 135?C, F =	B
Thermal Protection This is a feature which protects the motor from overheating and thus prolongs service life of the machine. In the event that the motor approaches overheating the thermal protection cuts power and only returns it after a cooling period.	AutoOverload

Motor HP	Horsepower. Used to indicate a fan's motor size.
Max BHP	Brake Horsepower. A measure of power consumption. Used to determine the proper motor horsepower and wiring.
Max Fan RPM	Revolutions Per Minute. Measure of maximum fan speed.
Min Fan RPM	Revolutions Per Minute. Measure of minimum fan speed.
Ps	Static Pressure. Resistance to airflow measured in inches of water gauge.
CFM	Cubic Feet Per Minute. A measure of airflow.
Sones	A measure of loudness. One sone can be approximated as the loudness of a quiet refrigerator at a distance of 5 feet. Sones follow a linear scale, that is, 10 sones are twice as loud as 5 sones.
