EV Car Motor Hairpin Stator production line


The motor stator production line is used for the manufacture of new energy vehicle hairpin motor stators.


Fully Automatic EV Car Hairpin Motor  Stator production line


The stator production line is used for the copper wire hairpin motor stator manufacturing. Hairpin motors are currently mainly used in new energy vehicles.The entire manufacturing process of the hairpin motor stator is highly automated and intelligent


The hairpin motor stator winding is the shape like a hairpin. In the motor stator manufacturing process, the winding is first made into a hairpin-like shape and then inserted into the stator slot, and then the ends of the hairpin are welded on the other end according to the design.

The hairpin motor process is threading, so the notch does not need to be fully opened, and the half-opened slot is beneficial to reduce the cogging torque. The winding structure of the hairpin motor stator is composed of n hairpins during the manufacturing process. The traditional flat copper wire motor is a formed winding;
