Explore industrial-grade motor manufacturing machines calibrated for high repeatability, zero copper enamel abrasion, and direct deployment into Cambodian industrial production lines. Every machine is rigorously factory-tested before international dispatch.
The automated insertion of enameled magnet wire coils and dielectric slot closure wedges into electrical steel stator laminations represents the most delicate, mechanically critical phase of electric motor manufacturing. Manual coil insertion suffers from high scrap rates due to mechanical abrasion of wire insulation, inconsistent slot fill ratios, operator fatigue, and long cycle times. Zunqi Intelligent Equipment designs industrial-grade automatic stator wedge paper and coil inserting machines that combine synchronous servo drive mechanisms with precision-ground tool-steel guide blades to insert full phase groups and wedge insulators in a single smooth, continuous mechanical stroke.
In modern induction, permanent magnet synchronous (PMSM), and brushless DC (BLDC) motor assembly, the coil inserting machine performs a tri-fold kinematic operation:
Continuous insulation paper (such as DMD, NMN, or Nomex) is drawn from coils, precisely measured by incremental encoders, creased into rigid structural profiles, cut to exact stack-length tolerances, and aligned directly underneath the insertion blades ready for instant transfer into the stator core slot openings.
Our dual-axis servo architecture controls the stroke acceleration and deceleration curves of the coil pushing fingers. This guarantees that copper or aluminum magnet wires enter stator slots under calibrated axial forces, preventing wire crossovers, inter-turn shorts, or tension-induced thinning of the copper conductor cross-section.
Every insertion blade, guide strip, and pushing finger is forged from Cr12MoV or imported high-alloy die steel, vacuum heat-treated to HRC 60-62, and precision finished to sub-micron surface roughness (Ra ≤ 0.2 μm). This mirror surface allows ultra-low friction gliding of wires even at dense slot fill ratios approaching 78%.
The manufacturing sector in the Kingdom of Cambodia is experiencing an unprecedented structural upgrade. Driven by the Royal Government of Cambodia's Industrial Development Policy (IDP 2015–2025) and bolstered by Qualified Investment Project (QIP) incentives administered by the Council for the Development of Cambodia (CDC), industrial capital is moving aggressively beyond garment assembly into electrical machinery, consumer appliance assembly, light electric mobility, and precision electro-mechanical components.
Automated stator coil inserting machines play a vital role across several key manufacturing clusters established within Cambodia's premier Special Economic Zones (SEZs):
Cambodia's tropical climate creates continuous domestic and regional export demand for ceiling fans, standing pedestal fans, exhaust systems, and evaporative air coolers. Motor assembly facilities located in Phnom Penh SEZ (PPSP) and Kandal Province require dependable coil inserting systems capable of handling 8-pole, 16-pole, and 32-pole single-phase asynchronous and BLDC stators. Our automated fan motor coil inserters handle thin copper and copper-clad aluminum wires (0.12 mm to 0.45 mm) without tension-breakage, maintaining cycle times under 15 seconds per stator.
The extensive agricultural zones flanking the Mekong and Tonle Sap basins—including Battambang, Kampong Cham, and Siem Reap—rely heavily on fractional and multi-horsepower submersible and centrifugal water pumps for irrigation and aquaculture. Pump motor stators demand deep-slot laminations, heavy gauge magnet wires (0.6 mm to 1.2 mm), and heavy-duty insulation papers to withstand high moisture and continuous running hours. Zunqi heavy-duty stator coil inserting machines feature reinforced hydraulic and servo rams capable of seating dense coil packets into deep pump lamination stacks up to 160 mm without slot tooth deformation.
Urban clean transportation initiatives in Phnom Penh and tourist transport transition in Angkor Archaeological Park have sparked rapid growth in electric two-wheelers, e-rickshaws, and light electric tuk-tuks. Producing high-torque permanent magnet hub motors and BLDC traction stators demands utmost precision in copper slot-fill percentage to maximize thermal dissipation and magnetic flux density. Our multi-station winding and automatic inserting machinery line enables Cambodian factories to localize high-efficiency EV drive production with automated wedge indexing and computerized tension controls.
Cambodia's border economic zones—such as Manhattan SEZ in Bavet (bordering Vietnam) and Poipet SEZ (bordering Thailand)—serve as key links in multinational "Thailand+1" and "Vietnam+1" manufacturing value chains. Tier-2 and Tier-3 electrical subcontractors operate here to supply global appliance OEMs. These export-driven plants require automated machinery that complies with international safety directives (CE, ISO9001), runs common industrial PLC platforms (Siemens, Delta, Mitsubishi), and offers fast tooling changeovers to support multiple motor frame sizes (IEC 56 through 132) on a single shop floor.
When selecting stator coil insertion equipment for a new manufacturing facility or automating an existing manual winding workshop in Cambodia, engineering managers must balance mechanical drive type, cycle speed, slot fill capacity, and tooling flexibility. The matrix below contrasts conventional manual methods against our semi-automatic and fully automated CNC servo coil inserting systems.

Investing in automated electric motor production lines in Cambodia requires an understanding of the country's macroeconomic fundamentals and manufacturing evolution. As local labor costs across traditional regional manufacturing powerhouses rise, Cambodia's favorable demographic dividend—with over 65% of the population under the age of 35—creates a highly trainable workforce suited for automated equipment operations.
Under Cambodia's upgraded Law on Investment, enterprises classified as Qualified Investment Projects (QIP) enjoy full exemptions on customs duties, special taxes, and Value Added Tax (VAT) when importing capital production equipment, machinery tooling, and construction materials for export-oriented factories.
The Ministry of Economy and Finance is actively driving industrial diversification. Motor winding, component lamination, and automated assembly are prioritized sub-sectors receiving preferential utility rates in state-backed special industrial zones.
The modernization of the Sihanoukville Autonomous Port (PAS) and direct logistics corridors linking Southern China's Pearl River Delta to Phnom Penh ensure that replacement tooling, custom inserter push rods, and spare parts arrive in Phnom Penh within 5 to 7 transit days.
