Glossary of Terms

 
Magnetic Polarity:
Distinguishes the location of north and south poles of a magnet. Magnetic lines of force emanate from the north pole of a magnet and terminate at the south pole.
 
Mechanical Rating:
The maximum power or torque a gear reducer can transmit. Many industrial reducers have a safety margin equal to 200% or more of their mechanical rating, allowing momentary overloads during start-up or other transient overloads.
 
Motor Types:
Classified by operating characteristics and/or type of power required. The AC induction motor is the most common. There are several kinds of AC (alternating current) induction motors, including, for single-phase operation: shaded pole, permanent split capacitor (PSC), split phase, capacitor start/induction run and capacitor start/capacitor run.Polyphase or three-phase motors are used in larger applications. Direct current (DC) motors are also common in industry as are gearmotors, brakemotors and other types. (See Chapter III for additional details).
 
Mounting:
The most common motor mounts include: rigid base, resilient base C face or D flange, and extended through bolts. (See Chapter IV for additional details). Gear reducers are similarly base-mounted, flangemounted, or shaft-mounted.
