From high-speed automated hairpin and double-end lacing assembly lines to precision commutators and Neodymium rotors, our portfolio meets strict ISO 9001 and CE compliance standards for heavy industrial deployment.
Machala, celebrated as the "Banana Capital of the World" and a primary hub for Ecuadorian aquaculture in the El Oro province, presents specific operational challenges for electric motors. The intersection of equatorial humidity, coastal salinity from Puerto Bolívar, and round-the-clock commercial operations demands electric motor stators of uncompromised structural integrity.
Standard stator manufacturing lines often overlook slot insulation failure caused by humid coastal environments. Our custom stator lines incorporate high-grade dielectric slot insulation insertion, dual-strand precision copper needle winding, and automated resin trickle-varnishing stations. This guarantees maximum resistance against galvanic corrosion, insulation puncture, and thermal degradation in aquaculture aeration pumps, packing conveyor motors, and refrigerated container ventilation drives.
Dielectric Strength: Capable of passing 1800V AC hipot tests under 90%+ relative atmospheric humidity.
Slot Fill Optimization: Up to 78% slot filling factor for compact, high-torque industrial pumping installations.
Anti-Corrosive Finish: Automatic varnish lamination guaranteeing class H (180°C) thermal insulation grade.
Contact UsOur automated stator lines operate as balanced, synchronized modular cells designed to prevent line stagnation, optimize cycle times, and support fast tooling changeovers for varying frame sizes.
High-speed servo-fed insulation paper insertion machines accurately position DMD, NMN, or Nomex films into stator laminations, shaping edges to prevent copper wire scoring during high-speed insertion.
Continuous flyer and multi-axis needle winding units wind enameled copper wire at up to 3000 RPM with digital tension feedback controllers, eliminating stretch, tension variances, and micro-cracking.
Precision insertion tooling introduces pre-wound coil groups and slot closure wedges into stator slots in a single stroke, avoiding coil crossing and preserving insulation integrity.
Hydraulic expansion and clamping mechanisms reshape stator end turns to exact internal and external clearance profiles, ensuring adequate spacing for rotor insertion and motor housing integration.
Dual-needle computerized lacing heads tie stator end turns using knot-by-knot, slot-by-slot, or segmented skip-slot configurations, tightening coils to prevent vibration-induced phase shorts.
Automated inline testing cabinets execute surge tests, DC resistance balancing, insulation resistance (Megger), and high-potential leakage diagnostics, with full traceability via MES network integration.

How automation is reshaping motor manufacturing, maintenance, and heavy machinery utilization in El Oro and South American export corridors.
Ecuadorian shrimp farms are replacing diesel engines with high-efficiency IE3/IE4 electric induction aerator motors to cut fuel expenses and reduce carbon footprints, driving regional demand for automated stator rewinding and volume production.
Machala's high-throughput packing plants are replacing manual packaging with automated sorting tables, cold-storage air blowers, and conveyor belts powered by fractional and medium-power BLDC and AC induction drives.
Urban delivery, agricultural light haulage, and municipal three-wheelers are turning to hub motors and mid-drive BLDC systems, sparking investments in flexible outer-rotor stator winding machinery.
To reduce long delivery lead times for imported spare motors, regional engineering facilities in Machala and Guayaquil are deploying automated stator manufacturing cells to build custom-wound units domestically.
