DC MOTORS
Winding Characteristics
Shunt Winding
made up of smaller gauge wire, more turns
Series Winding
made up of larger gauge wire, less turns
DC Motor types
Series (winding in series with Armature)
High starting Torque ... speed varies when load varies
Shunt (winding in parallel with Armature)
Constant speed ... less torque than a Series Motor
Permanent Magnet
Compound
DC motor Parts
Brushes
...
sit on the commutator sending current to the armature windings
Bearings
...
keep the armature centered with the stator
Enclosure
(frame of motor)
Armature
Armature windings
Shaft
... turns the load
Commutator
...
provides current to armature windings via brushes
Stator
(Field winding)
Enclosure Types
Totally enclosed
TENV (Totally enclosed Non-ventilated
TEFC ( Totally enclosed Fan cooled)
XP (Explosion Proof)
Open type
ODP (Open Drip Proof)
