Engineered for high slot fill factors, minimal enamel abrasion, and high operational reliability across industrial standard voltages (220V/440V 60Hz).
In alternating current (AC) induction motors, brushless direct current (BLDC) prime movers, and permanent magnet synchronous motors (PMSM), the stator winding assembly forms the magnetic core that dictates electromagnetic efficiency, thermal heat dissipation, and motor lifespan. Stator coil inserting—commonly referred to in electromechanical manufacturing as stator wire embedding or coil shooting—is one of the most critical mechanical operations in the manufacturing cycle. As industrial manufacturers throughout Guatemala City, Mixco, Villa Nueva, and the industrial corridor stretching down to Escuintla modernize their production infrastructure, transitioning from manual coil insertion to automated CNC dual-action insertion systems has become an imperative to reach export-grade quality standards.
The fundamental mechanical challenge of coil insertion centers on guiding pre-wound copper or copper-clad aluminum (CCA) magnet wire groupings into deeply recessed, semi-closed stator slots without inducing micro-scratches on the delicate polyurethane or polyamide-imide enamel insulation layers. A single dielectric insulation breach will lead to turn-to-turn short circuits, ground faults, and catastrophic motor breakdown during standard operation. Rilvo Automation’s stator coil inserting machines overcome this challenge through synchronised dual-motion tooling. The machine integrates a hardened tooling array consisting of guide blades, inserting push fingers, and wedge push rods controlled via high-torque AC servo drives. As the stator core is clamped into position, the guide blades penetrate through the inner bore of the stator lamination stack, accurately aligning with the stator tooth shoes. Simultaneously, the servo-driven pushing mechanism advances the coil turns into the slot cavities while pulling or pushing precision-creased slot wedge paper (insulation paper such as DMD, Nomex, or polyester film) into the slot mouth in a single seamless stroke.
Equipped with closed-loop multi-axis servo systems that govern insertion speed, deceleration ramps, and mechanical stroke depth down to ±0.02 mm precision, eliminating wire bunching and erratic tension spikes.
Integrated wedge insulation paper forming module unrolls, creases, cuts, and drives insulating wedges into the stator slots simultaneously with the coil bundle, ensuring zero wedge misplacement or drift.
Specially treated high-vanadium alloy insertion blades maintain tight tolerances, enabling stator slot fill factors up to 78% without pinching conductors or generating copper shavature during insertion.
In standard stator lamination architectures—ranging from IEC frame 63 up to 225—the geometry of the slot opening is deliberately restricted to reduce cogging torque and harmonic distortion. However, a restricted slot opening severely impedes traditional winding placement. Our DQ-1 and custom automated stator coil embedding series utilize a programmable variable-velocity profile. During the entry phase, the insertion fingers move at an optimized approach velocity of 80 to 120 mm/s. Once the coil bundles enter the narrow slot throat, the system dynamically balances hydraulic or servo thrust against mechanical back-pressure. This maintains conductor bundle cohesion and prevents wire crossover inside the slot cavity. Simultaneously, the wedge push rod drives the pre-creased insulating wedge directly behind the wire bundle, sealing the slot before individual conductors can rebound into the air gap.

Guatemala represents the largest industrial and manufacturing economy in Central America, with Guatemala City functioning as the corporate, logistics, and engineering epicenter. Across industrial parks located along Calzada Atanasio Tzul, Avenida Petapa (Zone 12), Mixco, and extending into the dynamic manufacturing hubs of Villa Nueva, Amatitlán, and the Palin-Escuintla industrial corridor, the demand for locally built and refurbished electric motors is expanding at an unprecedented pace. Rilvo Automation directly configures its stator coil inserting equipment to meet the specialized operating conditions and market requirements of Guatemalan industrial buyers.
Guatemala's extensive sugar mills (ingenios), banana plantations, and coffee washing mills depend heavily on multi-stage submersible pump motors. Our inserting machines handle heavy gauge windings for high-torque 4-pole and 6-pole submersible pump stators with exceptional insulation protection.
Guatemala City's growing food processing and cold-storage logistics operations require tens of thousands of shaded-pole and BLDC fan motors annually. Our automated coil insertion lines deliver rapid cycle times (under 15s) for high-volume fraction-horsepower stator production.
Serving heavy transport fleets operating between Puerto Quetzal and Guatemala City. Our equipment automates stator and rotor rewinding, wave coil shaping, and commutator fusing, replacing labor-intensive manual rewinding with standardized precision.
Machinery fabricators in Mixco and Villa Nueva build conveyor drives, industrial mixers, and packaging equipment. Our versatile tooling allows rapid changeover between different stator stack heights and slot numbers (24, 36, 48 slots).
Under the Dominican Republic-Central America Free Trade Agreement (CAFTA-DR) and the broader nearshoring momentum toward North and Central America, multinational manufacturing entities are actively expanding their supply chain presence in Guatemala. The strategic location between the Pacific (Puerto Quetzal) and the Atlantic (Santo Tomás de Castilla / Puerto Barrios) provides unmatched access to both North American and European shipping routes.
However, domestic motor rebuilders and electrical equipment assemblers face rising labor costs and acute shortages of master winding technicians capable of manual coil insertion. Manual winding insertion suffers from erratic tension, operator fatigue, high reject rates, and slot damage that compromises motor efficiency standards (such as IE2 and IE3 energy efficiency tiers). Rilvo Automation’s CNC stator inserting machines empower Guatemalan factories to leapfrog traditional manual operations, achieving repeatable, high-density coil placement that meets stringent international electrical standards.

Achieving defect-free motor stators requires tight synchronization between preceding coil winding operations, intermediate insulation insertion, and subsequent shaping and lacing. The following procedural breakdown illustrates how our machines integrate within modern industrial production workshops:
Pre-wound coil groups (produced via machines like the ZXB-1 or high-speed induction winders) are transferred onto the transfer tooling array. Conductor leads are organized into respective slot gaps to prevent crossing outside the core.
The insulated stator core is seated on the clamping station. High-precision tooling blades enter the stator bore from below, creating a polished, zero-clearance conduit directly against each stator tooth opening.
The servo push mechanism engages, simultaneously pushing the copper windings up through the blade channels into the slots while feeding the cut-and-folded insulation wedge strips to lock the winding securely in place.
