Fast torque response
It can output torque quickly after power-on and respond sensitively to load changes, delivering excellent dynamic performance.
Excellent speed regulation
The speed can be adjusted by changing voltage and current. It has a wide speed range and realizes smooth gear shifting.
Diverse power supply
It is compatible with DC batteries, regulated DC power supplies and other DC power sources, so it can work in areas without industrial power grids.
Great starting performance
It generates high starting torque and starts smoothly under load without stalling or insufficient power.
Simple control system
It does not require complex frequency conversion equipment. The wiring and control design are easy for installation and commissioning.
Low operating noise
It runs with slight vibration. The mechanical friction and electromagnetic noise are relatively low, meeting the noise control requirements of most workplaces.

Q: What are the common types of DC machines?
A:They are mainly divided into four categories: separately excited, series excited, shunt excited and compound excited. They differ greatly in torque characteristics and application scenarios.
Q:What is the biggest advantage of DC machines over AC machines?
A: They feature easy speed regulation and high starting torque, which make them more suitable for equipment requiring frequent start-stop and speed change.
Q:Why does a DC machine slow down after long-term operation?
A:It is usually caused by worn carbon brushes, insufficient lubrication for bearings, aging windings or low supply voltage. Replacing parts and routine maintenance can solve the problem.
