Direct factory configurations deployed across electrical remanufacturers, automotive rebuilding plants, and OEM motor lines. Fully compatible with 60 Hz Caribbean and South American operating grids.
Engineered for rectangular copper conductors and edgewise winding. Ideal for high-torque industrial armatures, generator field poles, and heavy vehicle traction coils requiring tight slot fill factors.
Automated multi-spindle stator winder with programmable jump, array, and indexing servos. Standard equipment for 2-to-8 pole industrial induction pump motors and HVAC blower packages.
High-speed hot-stake and spot welder for armature leads to commutator tangs. Closed-loop constant current feedback prevents lead crystallization and ensures uniform millivolt drop across segments.
Horizontal indexing trickling station featuring pre-heating, peristaltic resin metering, and cure tunnel integration. Delivers void-free Class H insulation for harsh chemical environments.
Medium-frequency inverter fusing station engineered specifically for copper-clad aluminum and fine magnet wires. Real-time displacement sensor shuts down cycle on insulation breach.
CNC-controlled tensioning and edge-guiding platform. Prevents enamel thinning during extreme radius bending for starter alternator rotors and high-amperage DC field poles.
Heavy rigid-bed CNC machining center for internal tooling production, rotor shaft turning, and lamination stamping die refurbishment. Essential for custom job shops and repair centers.
Diamond-tool precision turning lathe for armatures. Eliminates mica drag, delivers ultra-low total indicator reading (TIR < 0.003 mm), and guarantees maximum carbon brush service life.
Positioned centrally along the Sir Solomon Hochoy Highway, the Borough of Chaguanas serves as Trinidad & Tobago's vital commercial bridge between the Point Lisas Petrochemical Corridor and Northern logistical nodes.
Chaguanas maintenance centers and fabrication facilities support world-scale ammonia, methanol, and LNG trains located 10 minutes away at Point Lisas. Motors in these units undergo intense thermal stress, hydrogen sulfide exposure, and 24/7 duty cycles. Automation of rewinding with the SZD-376/63.5 varnishing station and precision rotor balancers ensures zero unpredicted MTBF drops.
Heavy DC slip-ring motors, bow thruster armatures, and port container spreader drive units constantly flow into Central Trinidad machine shops for overhaul. Implementing the SZC-3 CNC diamond commutator turning lathe and high-accuracy inverter resistance welders allows local workshops to recover commutators down to sub-micron runouts without costly offshore subcontracting.
As Chaguanas expands its Biljah and Brentwood industrial estates, food and beverage processing, packaging plants, and commercial transport fleets are replacing worn rewound units with energy-efficient IE3/IE4 motors. Utilizing the XB-1GZ induction stator winder enables local rewinding enterprises to achieve exact factory turns and slot compaction.
Caribbean Supply Chain Architecture: Procuring capital rotor equipment directly from Zhejiang Rilvo Automation allows Chaguanas manufacturers to eliminate multi-tier North American brokerage markups. Machinery ships factory-crated directly via international oceanic lanes to Port of Point Lisas or Port of Spain, accompanied by complete dual-voltage 460V/220V 60Hz Schneider/Delta PLC configurations.
Historical dependency on manual wire laying and oxy-acetylene brazing is rapidly sunsetting across the West Indies due to escalating copper scrap rates, labor shortages, and stringent IEEE 1068 motor repair standards.
Manual gas flame brazing introduces severe thermal annealing into commutator copper bars, inducing bar rise and premature brush dusting. The SDZ-130GS inverter spot welder delivers sub-millisecond current pulses with programmable electrode displacement, ensuring an immaculate molecular weld nugget.
Using manual toolposts on engine lathes tears copper burrs across mica slots. Our SZC-3 CNC lathe operates PCD (polycrystalline diamond) tooling at up to 3,500 RPM, maintaining surface finishes below Ra 0.4 μm without necessitating tedious manual mica undercutting.
Atmospheric dip-and-bake tanks leave large air bubbles deep within rotor core slots, triggering partial discharge and early winding breakdown in tropical humidity. The SZD-376/63.5 trickling machine meters resin directly into rotating heated pre-slots, yielding 100% solid fill.
Heavy downhole electric submersible pumps (ESPs) require flat profile rectangular conductors to maximize thermal dissipation. Dedicated coil winders like the CJL-7 and ZXB-1 execute edge-bending with zero kinking, preserving insulation integrity under 2,000 psi hydrostatic heads.

Headquartered in the Shatianyang Industrial Development Zone of Sanmen, Taizhou, Rilvo integrates in-house precision casting, five-axis CNC machining, and automated software validation under strict ISO9001 governance.
Our 36-member engineering unit specializes in matching rotor slot configurations, commutator tang geometries, and wire gauge variations. Send your rotor or lamination DWG/STEP drawings, and we engineer custom nests, collets, and winding flyers within 10 working days.
We do not dispatch dry machinery. Every unit ordered by Trinidadian buyers undergoes a continuous 72-hour trial run using customer-supplied raw laminations, shafts, and magnet wire. High-definition test videos, cycle time charts, and micrometer runout inspection records are submitted before dispatch.
With fast access to Ningbo maritime terminals, we ship under standard CIF Port of Point Lisas or FOB Ningbo terms. Equipment arrives with bilingual electrical schematics, complete spare wear-part sets (winding flyers, nozzles, tungsten electrodes), and remote engineer-assisted live video commissioning.
Essential operational, customs, electrical, and commercial information for Caribbean procurement directors, factory engineers, and workshop principals.
Whether you are expanding a heavy electric motor repair depot or installing an automated OEM armature assembly line, our engineering division will configure the optimal machinery package matching your exact slot count, wire gauge, and throughput targets.
