Explore our core automation machinery engineered for multi-pole induction motors, brushless DC units, ceiling fan stators, and agricultural pump systems operating in Southeast Asia.
A comprehensive technical evaluation of electrical motor assembly demands, local infrastructure synergy, and manufacturing modernization across the Isan industrial gateway.
Nakhon Ratchasima (Korat) has evolved from an agrarian anchor into Thailand's northeastern powerhouse for electromechanical component sub-assembly, automotive subcontracting, and HVAC component fabrication. As industrial estates such as the Suranaree Industrial Zone expand their tier-2 and tier-3 supplier networks, manufacturing facilities face heightened requirements for electro-mechanical efficiency (IE3 and IE4 efficiency standards).
The stator coil lacing process serves as the structural linchpin of electric motor manufacturing. In tropical environments like Thailand, loose winding end-turns lead to continuous mechanical micro-vibrations, thermal hot spots, and early dielectric breakdown due to fluctuating humidity levels. Modernizing stator production lines with high-speed, servo-controlled single-side and double-side lacing machines guarantees mechanical rigidity, consistent tensioning, and identical slot-phase separation across high-volume assembly shifts.
The operational landscape in Nakhon Ratchasima demands specialized stator winding and binding configurations tailored to distinct regional applications:
Achieving zero electrical defect rates demands synchronizing lacing machinery with antecedent coil insertion and subsequent final forming stages.
Prior to lacing, stator coils and slot wedges must be inserted in a unified, non-destructive stroke. Tooling matched precisely to the stator's internal diameter eliminates wire cross-over pinches, establishing optimal coil clearance for binding needles.
Our HF-BS20 series utilizes independent servo drives for top and bottom binding needles, hook heads, and stator rotary indexing tables. Program variable pitch, slot-skipping, and continuous perimeter binding directly via the multilingual industrial touchscreen.
Following lacing, stators undergo expansion and axial pressing in machines like the HF-W120H. The lacing cord maintains end-turn structural integrity while hydraulic dies establish exact external diameters, ensuring effortless motor casing assembly.
