Description

The MN4112 motor from T-Motor’s Antigravity series represents a high-efficiency powerplant for demanding aerial cinematography and heavy-lift applications. Its design prioritizes a high thrust-to-weight ratio while maintaining exceptional thermal management through a proprietary centrifugal cooling architecture that directly ventilates the stator windings.

Built with a single thick 16AWG copper wire per tooth, the motor minimizes resistive losses (60mΩ internal resistance) and is insulated to a 220°C Class C temperature rating. The rotor is precision-balanced to under 5mg, drastically reducing harmonic vibrations that can interfere with gimbal and camera performance. The motor’s 12N14P magnetic configuration provides smooth torque delivery suitable for large propellers up to 15×5 inches.

Key Features

  • Antigravity Cooling System: Centrifugal airflow design actively cools the stator windings, allowing sustained high-power operation and an 18% increase in heat dissipation.
  • High-Temp Windings: Utilizes 220°C high-temperature resistance copper wire (Class C insulation), validated by a 500V/5s coil insulation test.
  • Precision Dynamic Balance: Rotor balanced to a standard of less than 5mg, ensuring minimal vibration for smooth cinematic footage.
  • High-Strength Construction: Machined from high-strength aluminum alloy with a 6mm inner shaft diameter for rigidity.
  • Optimized Magnetic Circuit: 12N14P configuration provides efficient torque and smooth rotation for large-diameter propellers.
  • Environmental Protection: Rated IP45 for resistance against dust and water spray.

Applications

  • Heavy-lift cinematic drone platforms carrying DSLR or mirrorless camera systems.
  • VTOL (Vertical Take-Off and Landing) and hybrid fixed-wing UAVs requiring high-torque motors.
  • Industrial inspection and mapping drones with heavy sensor payloads.
  • Large-format FPV drones designed for long-range, stabilized aerial filming.

Frequently Asked Questions

What is the recommended ESC for the T-Motor MN4112 KV420?

A minimum 40A continuous-rated ESC is recommended, with a peak current capability of at least 54A to match the motor's 180-second burst rating. For optimal performance on 6S LiPo, use a high-quality BLHeli_32 or BLHeli_S ESC with sufficient thermal headroom.

What size propeller is best suited for this motor?

The motor is optimized for large-diameter, high-pitch propellers, with a specific recommendation of 15x5 inches. This prop size efficiently converts the motor's high torque into thrust for heavy-lift applications. Always ensure your frame and propeller clearance can accommodate this size.

Can the MN4112 motor be used on a 4S battery system?

While technically possible, using it on 4S will significantly reduce its RPM and thrust output, as KV is RPM per Volt. It is engineered and rated for 6S operation (up to ~25.2V). For optimal efficiency and performance as designed, a 6S LiPo battery pack is required.

What does the IP45 protection rating mean for this motor?

An IP45 rating indicates the motor is protected against solid objects larger than 1mm (dust level 4) and against water jets from any direction (water level 5). This makes it suitable for operation in outdoor environments with light rain or spray, but it is not submersible.
