Erdenet stands as one of Northern Asia’s most vital industrial epicenters, anchored by the massive Erdenet Mining Corporation (EMC), one of the premier copper and molybdenum processing enterprises globally. Operating machinery in Erdenet requires motion control hardware capable of enduring extreme continental climate fluctuations—where ambient temperatures plunge to -40°C during severe winters and climb up to +35°C in summer.
Standard off-the-shelf micro motors often fail prematurely in Erdenet due to gear lubricant congelation, shaft embrittlement, optical encoder lens fogging, and heavy silica dust ingress. RSI Motors provides custom-engineered DC motors integrated with magnetic Hall-effect encoders and sub-zero synthetic grease formulations tailored specifically for Mongolian industrial operators, power plants, and mining logistics infrastructure.
Low-temperature synthetic lubricants prevent gearbox locking during arctic winter stops in Erdenet.
Immune to heavy vibration, dust, and moisture that typically blind standard optical encoder disks.
Hardened alloy gears (hobbed in-house) encased in dust-tight housings built for continuous ore crushing plants.
Up to 4096 PPR resolution guaranteeing accurate speed and position control in automated processes.

From heavy copper concentrate processing to sub-zero municipal utility infrastructure.
In Erdenet's massive copper flotation plant, precise chemical dosing requires strict closed-loop motor positioning. Our GMP36 planetary gear motors with magnetic encoders provide exact valve opening angles, unaffected by heavy slurry splash or electromagnetic interference from neighboring high-voltage grinding mills.
The Erdenet Thermal Power Plant and electrical substations rely on automated switchgears and air damper controllers during harsh winters. Utilizing sub-zero synthetic ester greases and custom shaft seals, RSI Motors' GM37 24V encoder motors function flawlessly down to -40°C without freeze-up failures.
Autonomous robotics and crawler vehicles inspecting underground ore passes require compact, high-torque hub drives. Our TT-100W Hub Gear Motors with Encoders deliver precise odometry and feedback tracking over uneven, rock-strewn terrain.
Assay laboratories in Orkhon Province analyzing copper purity levels demand sub-micron linear displacement accuracy. Our N20 micro motors with 4096 PPR encoders power automated titrators and robotic pipettes with zero backlash accumulated error.
Sourcing micro DC motors from RSI Motors gives Mongolian industrial buyers a decisive supply chain advantage. Operating out of our advanced lean manufacturing facility in China, we leverage direct trans-continental railway networks passing through the Erenhot / Zamiin-Uud border corridor straight to Ulaanbaatar and Erdenet.
Expert answers regarding motor selection, low-temperature adaptation, encoder signaling, and international shipping to Mongolia.
Erdenet's industrial environment contains heavy concentrations of fine airborne dust and severe vibration from ore crushers. Optical encoder disks can get blinded by dust coating the optical sensor lens. Magnetic Hall encoders use solid-state magnetic sensors and target magnets sealed inside the motor rear cover, making them completely immune to dust, shock, and moisture condensation.
Standard off-the-shelf motors fail in freezing temperatures because conventional grease solidifies into a thick gel, overloading the gear train and burning out the motor coils. We supply motors intended for Northern Asia with specialized low-viscosity synthetic ester grease rated for -50°C to +120°C, combined with cold-resistant rubber seals and high-grade copper magnet wire.
Yes. As a direct manufacturer, we offer custom gear ratios ranging from 1:5 up to 1:1500 across spur and planetary gearboxes. Encoder resolutions can be configured from basic 3 PPR speed monitoring magnetic discs up to high-precision 4096 PPR quadrature encoders for exacting positional control.
All RSI Motors shipments are certified under ISO9001 quality management standards and comply fully with CE, RoHS, and REACH directives. Material test reports, dimensional inspection sheets, and encoder pinout schematics are provided with every export batch.
Our products are packaged using heavy-duty molded EPE foam trays enclosed in double-walled corrugated cartons, followed by vacuum-sealed moisture barrier bags and export-grade wooden pallets to guarantee zero damage during trans-Mongolian rail transit.
Standard catalog models ship within 7-10 business days. Custom engineering requests (special voltage windings, shaft turnings, IP67 cabling) typically require 15-20 days for mass production, with direct express rail transit reaching Ulaanbaatar and Erdenet in 5-8 days.
Whether you require heavy-duty planetary gear motors for mining actuators or high-resolution micro drives for automated sampling systems, RSI Motors delivers tested reliability backed by decades of engineering expertise.
