AC Winding Department The AC Winding Department is responsible to rewind electrical motors using only class H insulation material. The winding department utilizes a Samatic-winding machine for efficiently manufacturing coils. The winding data is verified with the use of EASA Motor Winding Design Program prior to winding coils. The AC winding supervisor, who along with the winding technician signs off all-winding data and test results, verifies all winding data and layouts. Department Image Samatic Winding Machine Rewinding ENERGY EFFICIENT (premium) MOTORS and still MAINTAINING motor efficiency is easy with SAMATIC. In fact, there is NO ALTERNATIVE TO SAMATIC! Here is why: Energy efficient motor design requires a large number of turns per coil slot (high FILL RATIO). These motors are mostly concentric wound. SAMATIC, with its special layering and tensioning features and its special Adjustable Concentric Heads, is the perfect tool to achieve the highest SLOT DENSITY/FILL RATIO, in any coil shape, and particularly in the concentric winding method. SAMATIC Image 1 SAMATIC Image 2 Epoxylite Cutoff Saw The carbide tipped cutoff saw blade turns at 7000 rpm and removes one end of the winding in a stator so that once the burn-off process is completed, the windings can be removed from the stator core easily. 2000 HP stator Wound with high density untreated VPI form coils designed for 4160 V usage. These coils are manufactured by Kencoil, which has been proven to exceed industry standards by far. 700 HP synchronous stator in different phases of the rewinding process
