Series circuit connection
The excitation winding and armature winding are connected in series and powered by the same power source. The armature current is equal to the excitation current.
Dramatic torque-speed variation
The speed rises sharply under no-load or light-load conditions, and decreases obviously as the load increases. Its speed and torque are in strong inverse proportion.
High starting torque
It can generate extremely large torque immediately after power on, delivering excellent performance for start-up under load.
Powerful output
Under the same size and power rating, it produces higher torque than other DC motors, ideal for heavy-load start-up.
Simple structure
The series connection simplifies external wiring. Its compact structure brings low difficulty in manufacturing and assembly.
Good resistance to impact load
It can adjust speed adaptively when encountering sudden load changes, and is not easy to stall or get damaged.

Q: Can a DC series motor run with no load?
A:No. The motor will run far beyond its rated speed under no-load condition, which may cause rotor damage and component failure. No-load or light-load operation is strictly prohibited.
Q: What equipment is a DC series motor suitable for?
A:It is widely applied in forklifts, cranes, electric vehicles and power tools that require heavy-load start and frequent start-stop.
Q:How to reverse the rotation direction of a DC series motor?
