You start a wind at the back and finish at the front of the motor, giving the extra half wind. I don't see how you would make a delta wind with 4.0 wraps. I have not seen this explained anywhere though. I have just seen the inside of several motors. The trinity 3 wind motor does not have this solder ring on the pinion end of the motor. It is a y wind as stated by Trinnity just below. Y just means that two coils start at one solder point and then y off into two coils. That is what I think it means. Coils start and terminate at the back of the motor. Definitely a different type of wind than the Novak. Delta just means the start and end of the coil are separated by some distance along the length of the motor.
