DC motor serial Resistance Speed Control Simulation

Selection Module

1. DC-motor (DC motor)

2. Breaker Circuit Breaker

3. Speed Control resistor R (20 Gb/s)

4. DC power supply e and EF (both 240 V)

5. Step (Circuit Breaker Control signal)

Changes at 5s and 10 s respectively

6. other types include grounding, signal splitter, and oscilloscope.

7. simulation parameter settings

Simulation results:

Motor Speed ω Waveform

Armature Current Waveform

Excitation Current Waveform

Electromagnetic torque waveform

There are three methods to adjust the speed of a DC Motor

1. Adjust the armature Voltage

2. Change Excitation

3. Change the Armature Loop Resistance
