T-MOTOR MN11-13 Series: Heavy-Lift Multirotor Propulsion System

You will find that the takeoff weight of drones continues to increase, projects such as logistics transportation, emergency rescue, agricultural plant protection, and heavy-duty inspection demand increasingly stringent motor performance in thrust, heat dissipation, and environmental adaptability.

In the spring of 2026, T-MOTOR has officially launched the MN11-13 Series Heavy-Lift Multirotor Power System, filling a critical power gap for industrial drones with an MTOW of 50-140kg (quadcopter).

Built upon the core values of “High Payload, Long Lifespan, and High Environmental Adaptability”, the new MN series provides a complete power solution that seamlessly bridges the gap between medium and ultra-heavy industrial drones. This comprehensive lineup delivers the powerful thrust required for demanding missions, including heavy-lift logistics, firefighting and rescue, commercial delivery, and large-scale agricultural spraying.

Selection Guide

Expanding our flagship lineup, the MN11-13 series focuses on meeting the demands of high-payload applications. Below are the key parameters of the new products, including maximum thrust per arm, rated thrust per arm, motor weight, and KV, to help you select the right model for your mission requirements.

 Core Features

High Environmental Adaptability and Protection Rating

Equipped with dual dust-mesh structure for rotor and stator, the MN series achieves an IP45 rating while remaining remarkably lightweight.

Lab tests confirm:

-Zero internal dust accumulation after extreme exposure.

-Consistent insulation performance and normal operation.

It is engineered to withstand water spray or heavy rain, significantly improving stability in harsh industrial environments such as rain, fog, and dust, and filling the protection gap for heavy-lift motors in long-term outdoor operations.

Ultra-Long Service Life and High Reliability

With MTBF ≥ 2000 hours and an operating temperature range of -30℃ to +55℃, the system meets the demands of heavy-lift drones for continuous high-frequency operations.

It provides reliable, all-weather support for critical heavy-lift missions, including emergency firefighting and logistics transportation.

Integrated High-Efficiency Cooling System

The motor features a built-in one-piece die-cast cooling fin structure. The heat dissipation area is doubled than traditional split cooling structures, resulting in higher cooling efficiency and reducing winding temperature by 5-8°C.

It effectively solves the overheating risks under heavy loads and reduces power loss during prolonged continuous operation.

Recommended Combinations

We provide the following recommended combinations to simplify pairing and ensure the best balance of thrust, endurance, and safety. These allow precise selection according to different MTOW requirements.

Customization

To better meet the specific technical requirements of different projects and brands, the T-MOTOR MN series offers comprehensive customization services.

We provide custom aesthetics and laser-marking, alongside critical technical options such as temperature sensing, KV optimization, mounting patterns, wire length, and other hardware specifications.
