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.
