New energy motor shaft
The rotor of a new-energy motor is the core rotating component of new-energy vehicles, industrial servo motors, and permanent-magnet synchronous motors. Working in conjunction with the stator, it facilitates the mutual conversion between electromagnetic energy and mechanical energy. The rotor directly determines the motor’s speed, torque, efficiency, and operational stability. It is a typical workpiece requiring high-precision, high-rigidity, and high-consistency machining in the field of new-energy equipment manufacturing. Its machining processes encompass key techniques such as turning, milling, drilling, and precision boring, placing stringent demands on tool dimensional accuracy, cutting edge sharpness, and machining stability.
The rotors of new-energy vehicle motors typically feature a metal core shaft combined with a structure made of stacked permanent magnets or silicon steel laminations. The key machining features include the outer circle of the rotor shaft, stepped surfaces, shaft shoulders, keyways, positioning holes, and end-face stop rings. The rotor core shafts are often made from alloy structural steels such as 40Cr and 20CrMnTi. Since the silicon steel lamination stacks are prone to generating burrs during machining, it is essential to simultaneously meet both the geometric tolerances—such as roundness and cylindricity—for shaft components and the requirement for burr-free machining of the laminated assemblies.
