Product Manual

Transformer: Used to isolate line voltage from a circuit or to change
voltage and current to lower or higher values. Constructed of primary
and secondary windings around a common magnetic core.
Underwriters Laboratories (UL): Independent United States testing
organization that sets safety standards for motors and other electrical
equipment.
Vector Drive: An AC drive with enhanced processing capability that
provides positioning accuracy and fast response to speed and torque
changes. Often used with feedback devices in a closed-loop system.
Voltage: A unit of electromotive force that, when applied to conduc-
tors, will produce current in the conductors.
Watt: The amount of power required to maintain a current of 1 ampere
at a pressure of one volt when the two are in phase with each other. One
horsepower is equal to 746 watts.
Winding: Typically refers to the process of wrapping coils of copper
wire around a core. In an AC induction motor, the primary winding is a
stator consisting of wire coils inserted into slots within steel laminations.
The secondary winding of an AC induction motor is usually not a
winding at all, but rather a cast rotor assembly. In a permanent magnet
DC motor, the winding is the rotating armature.
