What are the advantages and disadvantages of DC cars?

DC motor has good start-up characteristics and speed regulation characteristics, which can provide large start-up current when starting to ensure the smooth start-up of the motor, and at the same time, speed regulation can be realized by changing armature or excitation current.

The manufacturing process of DC motor is relatively simple, the manufacturing cost is low and the maintenance is relatively easy.

The noise and vibration produced by DC motor during operation are small, and the impact on the environment is small.

Disadvantages of DC motor:

Because of its structure and working principle, DC motor has a large moment of inertia, which is not suitable for high-speed operation and frequent start-stop

The commutator of DC motor is easy to wear and needs regular maintenance and replacement, which increases the use cost and maintenance workload.

The power density of DC motor is relatively low, which requires more space to install, and is not suitable for applications requiring high power density.
