Motor Shaft

A motor shaft is a core rotating component of an electric motor, primarily responsible for transmitting the torque generated by the motor's rotor to external mechanical equipment (such as pumps, fans, reducers, or conveyors). It serves as the key connection between the motor's internal power output and the external working mechanism, ensuring stable power transmission during the motor's operation.

Motor shafts typically require high dimensional accuracy and concentricity to minimize vibration and noise during high-speed rotation. Common materials used for manufacturing motor shafts include carbon steel (e.g., 45# steel) and alloy steel (e.g., 40Cr), which may undergo heat treatment processes (such as quenching and tempering) to enhance their mechanical properties like strength, wear resistance, and fatigue resistance, adapting to different load and speed requirements of motors.
