In an alternator short pitch coils are used
WebA coil with a span of less than 180° electrical is called a fractional-pitch coil. For example, a coil with a span of 150° electrical would be called a 5/6 pitch coil. Although e.m.f. induced in a fractional-pitch coil is less than that of a full-pitch coil, fractional-pitch coils are frequently WebFind many great new & used options and get the best deals for Mercedes alternator regulator OM615 OM616 0021543206 Bosch 0192052005 EE 14 V3 at the best online prices at eBay!
