Description

The T-Motor Navigator MN505-S is a purpose-built industrial motor designed for reliability in harsh environments. Its waterproof sealing (IP45) and anti-corrosion treatments protect the stator and internal components from moisture, salt spray, and particulate ingress, making it ideal for marine robotics and heavy-lift UAV platforms.

Engineered for high torque and thermal efficiency, the motor utilizes a 24N28P magnetic configuration and Level E magnets capable of withstanding temperatures up to 180°C. The centrifugal cooling design and high-temperature wire insulation ensure stable performance under continuous high-load conditions, supported by precision 696ZZ bearings for smooth operation.

Key Features

  • Waterproof & Corrosion-Resistant: IP45-rated sealed housing protects against water and dust ingress for marine and outdoor use.
  • High-Temperature Endurance: Features 180°C (Level E) high-temperature magnets and 220°C (Level C) insulation for reliable operation under thermal stress.
  • Dual Shaft Design: Provides a 6mm inner shaft and 4mm outer shaft for versatile mounting compatibility with various propeller adapters and direct-drive systems.
  • Precision Dynamic Balance: Rotor balanced to ≤5mg and motor assembly to ≤10mg standards for minimal vibration and extended bearing life.
  • Robust Electrical Construction: 16AWG silicone cables (150mm length) and 500V coil insulation ensure safe, high-current power delivery.
  • Centrifugal Cooling: Integrated design enhances airflow over the stator for improved thermal management during sustained high-power operation.

Applications

  • Underwater Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) requiring waterproof propulsion.
  • Heavy-lift industrial UAVs and cargo drones operating in wet or dusty outdoor environments.
  • Marine surface vehicles and amphibious drones where corrosion resistance is critical.
  • High-endurance aerial mapping and surveying platforms using 6S power systems.
  • Custom robotics platforms requiring a high-torque, sealed brushless motor solution.

Frequently Asked Questions

What is the maximum recommended input voltage for the MN505-S 320KV motor?

The T-Motor Navigator MN505-S is rated for 6S LiPo battery systems, with a nominal voltage of 22.2V. While it can handle typical voltage spikes associated with 6S operation, exceeding this voltage range with higher cell counts (e.g., 8S) is not recommended as it may lead to excessive heat, reduced magnet life, or insulation failure.

What does the IP45 protection rating mean for this motor?

The IP45 rating indicates the motor is protected against solid objects larger than 1mm (IP4X) and against water sprayed from any direction (IPX5). This makes it suitable for use in damp, rainy, or dusty environments, but it is not designed for full submersion. For underwater ROV applications, additional external sealing of connectors is often required.

What type of Electronic Speed Controller (ESC) is compatible with this motor?

This motor requires a brushless ESC capable of handling 6S voltage and the current demands of the MN505-S under load. A high-quality industrial or marine-grade ESC with active cooling and waterproofing is recommended. Ensure the ESC firmware (e.g., BLHeli_S, BLHeli_32) supports the motor's low KV and pole count for smooth operation.

What are the mounting requirements and shaft specifications?

The motor features dual shaft diameters: a 6mm inner shaft and a 4mm outer shaft. Mounting requires M3 screws, with the package including both M3*10mm and M3*8mm options. Crucially, the internal thread depth must not exceed 5mm to avoid damaging the stator assembly. Use appropriate propeller adapters or direct-drive mounts compatible with the 4mm or 6mm shaft.

Package Includes

  • 1 x T-Motor Navigator Waterproof MN505-S 320KV Motor
  • 1 x Accessories Set (2x M3*10mm Mounting Screws, 1x Cover, 4x M3*8mm Motor Mounting Screws)
