Motor Action
repulsion and attraction caused by magnetism that dictates the motion of a conductor through a magnetic field
RPMS
measure of rotational speed
Rotor
the rotating part of the motor
Stator
the stationary part of the motor
Torque
Measure of rotating force
Neutral plane
the armature position in which no torque is being produced (in a motor)
Counter Electromotive Force (CEMF)
voltage produced inside a motor that opposes the applied voltage
In-rush Current
current that is drawn when a device is first connected to power.
Locked rotor current (LRC)
current through the armature when voltage is applied, but the rotor is prevented from turning
Series Motor
a self-excited motor with field windings connected in series with the armature
Shunt Motor
self-excited motor with field windings connected in parallel with the armature
Compound Motor
a self-excited motor with both series and shunt field windings
Cumulatively compound motor
compound motor wherein the series and shunt coils are aligned magnetically and aid one another
Differentially compound motor
compound motor wherein the series and shunt coils are misaligned magnetically and oppose one another
