The performance of the DC motor is closely related to its excitation mode. There are usually four kinds of DC motor excitation modes: DC Hex motor, DC shunt motor, DC series motor and DC rectifier motor. Master the four ways their own characteristics:
1. DC He excitation motor: excitation winding and armature no electricity contact, the excitation circuit is supplied by another DC power supply. So the excitation current is not affected by the armature terminal voltage or armature current.
2. DC shunt motor: circuit parallel, shunt, and the voltage across the winding is the voltage across the armature, but the excitation
The winding is wound around a thin wire with a large number of turns, so it has a large resistance, making it smaller through his excitation current.
3. DC series motor: the current series, partial pressure, excitation winding is connected in series with the armature, so the motor within the magnetic field with the armature current changes have significant changes. In order to make the excitation windings do not cause large losses and voltage drop, the smaller the better the resistance of the field winding, so the DC series motor is usually wound with thicker wires, and the number of turns is less.
4. DC Torque: The magnetic flux of the motor is generated by the excitation current in the two windings.
Divided into two parts: stator and rotor. Note: Do not confuse the commutation pole with the commutator.
The stator includes: main pole, base, commutator pole, brush device and so on.
The rotor includes: armature core, armature (shu) windings, commutator, shaft and fan.
