In motors with separate amplifier, the excitation current is independent of voltage source mencatunya. Capstan will decreases with increasing torque moments, as shown in Figure 4.25b.
2. Shunt Motor Characteristics
The series shunt motor excitation parallel to the anchor. Round-up will go down with his moment of torque. In the no-load condition, the characteristics of a shunt motor is similar to the motor with a separate amplifier.
Among other types of DC motors, series motors require the greatest moment of starting torque. Things to note, that the motor should not be operated in a series of no-load condition.
4 Characteristics of Compound Motor
In this motor, the main pole containing series and parallel circuits. In the no-load condition, the nature of such a compound motor has a shunt motor. Mounted on load conditions, with the same torque moment, will come round a little higher.
