17 mar 2023 · In the design of a hairpin winding, it is possible to influence the transient potential differences by employing a method called “shifting” within the winding scheme and thus to reduce the maximum potential differences that occur.
10 mar 2023 · This paper investigates the effect of hairpin winding topology on the electromagnetic and thermal performance in order to improve the torque, power density and efficiency of traction motors.
Abstract: Compared to traditional windings, hairpin windings feature higher fill factors and increased robustness to mechanical stresses. However, due to the high cross-sectional area of the rectangular conductors, the current density is not uniform when the motor operates at high speeds.
