Fig. 1. An example of a hairpin turn. Photo courtesy of RallySportLive. The interaction between tire and road is complex, and differ-ent tires have different characteristics. Even when only consid-ering the longitudinal stiffness, the experimental values differ considerably between tires, and the variability can typically be 20–100 %, see [5].
Abstract—In this paper, the voltage distribution in hairpin winding of traction motors fed by high-switching frequency inverters is discussed. The voltage distribution is calculated using a method based on a combination of analytical and numerical analyses, the final model parameters are computed using finite element approach.
... start position in the hairpin turn was (X p,0 , Y p,0 ) = (−5, 0) m for all models, and the initial and final heading angles were aligned with the road direction. Figures 11-12 show the...
Hairpins. A hairpin is a corner which turns about 180 degrees. In this case, the apex for the racing line is about three quarters of the way around the bend (see Diagram 4). A useful guide is that halfway through the turn you should be roughly in the middle of the track.
For hairpin windings, the rectangular conductors in each slot are arranged in layers. To form a winding, connections between the conductors are made, which are defined by the winding algorithm. General de-sign guidelines for hairpin winding with a multitude of parallel branches per phase are described in [ 10].
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.
