ARMATURES AND FIELD COILS

Sinotech can ensure excellent quality armatures and field coils from China and is very price competitive. Sinotech has audited, qualified and worked with QS-9000 and ISO certified armature and coil factories in China for over 12 years. Sinotech is dedicated to delivering armatures from China to you at lower prices but the same quality, service and terms as a domestic supplier.

Along with its intelligent manufacturing processes, Sinotech-audited facilities in China provide low cost solutions for winding with a variety of customer requirements on precision, compaction, complication and sophistication.

Sinotech is truly one of the few remaining totally integrated suppliers of specialty custom windings in the electromechanical motor and gyro industries. All laminations are stacked using critically designed stacking tools and fixtures. This is one of our specialties and the heart of our business.

Our superior machining capabilities enable us to commonly manufacture to .0003" tolerances total on O.D.'s and I.D.'s. If the application demands, closer tolerances can be obtained. Sinotech builds custom bobbin windings which employ unique transfer molding technology for high dielectric requirements up to 1,500 volts.
