UAS BRUSHLESS MOTORS

  • What motor edition is ideal for the DJI™ Phantom® 3 Series?

    • The KDEPSK-2315-885 Power System Kit is the ideal upgrade package for the Phantom® 3 series, and provides the full quad-motor setup for direct installation to the airframe. Containing four (4) of the KDE2315XF-885 Brushless Motors and Adapters for optimal performance with the standard battery system (4S voltage) and are directly-compatible with the stock ESCs for drop-in operation. Please feel free to review the Installation Instructions for additional details.
  • What motor edition is ideal for the DJI™ Phantom® 2 Series?

    • The KDEPSK-2315-965 Power System Kit is the ideal upgrade package for the Phantom® 2 series, and provides the full quad-motor setup for direct installation to the airframe.  Containing four (4) of the KDE2315XF-965 Brushless Motors and Adapters for optimal performance with the standard battery system (3S voltage) and are directly-compatible with the stock ESCs for drop-in operation.  Please feel free to review the Installation Instructions for additional details.
  • What is the temperature rating of KDE Direct UAS Brushless Motors?

    • The entire motor is rated to over 400°F (windings rated to 240°C and magnets to 180°C), so no concerns of any damage from heat-generation. In actuality, when the motor is running in the flight, the centrifugal fan is efficient at keeping the motor cool and consistent, designed to run around 120°F-140°F during a flight for optimal performance. When you land and shut down the centrifugal fan, you’ll experience a motor that feels much hotter than during operation, simply due to the high-performance design of the motor. With high-performance motors, there is a high-copper concentration stored in the motor which naturally stores heat during flight. When the fan is shutdown, all the heat is expelled to the outer case and what you are feeling is the heat conducting to the Aluminum Fan, as it’s designed to do. In this, the temperature may feel hot, but this is normal for all high-performance motors and nothing of concern due to the quality of the components.
  • How often should bearings and shafts be replaced on KDE Direct UAS Brushless Motors?

    • KDE Direct is currently developing the maintenance schedules for the multi-rotor (UAS) product series. KDE Direct is actively developing test studies to finalize the maintenance recommendations and accuracy in a wide-range of applications worldwide. There are many outside factors that can have a large impact on each device over their life span; including environmental effects outside of our control (such as sand-conditions, hot-temperatures, or saline). In most applications, the lifespan of the brushless motors is determined by the manufacturer’s recommendation of bearing life - all of which our designs use NMB and NSK-brand, Japanese bearings stating a lifespan of approximately 200 hours in normal conditions. For the shafts, we recommend replacement every 400 hours of use in normal conditions, or when visible damage/fretting is found at the bearing interfaces from natural wear. With proper maintenance, all of our devices can last for many years of safe operation in most applications. Bearing and Shaft Replacement Kits can be purchased online for the UAS product series, as well as Replacement Kits for the single-rotor series.
  • Anything to expect from the motor on the first flight?

    • The UAS Brushless Motors are near maintenance-free (triple-bearing supported) and won't require anything when first received - simply bolt in the motor and ready for operation. The motors have a specialized varnish applied to the windings to prevent any shorts or shifting when the motor is energized (more expensive manufacturing, but high-quality) and as such, may produce a minor electrical smell during the first few flights when brand new. This is in similar fashion to buying a new car, where the engine compartment will produce varnish vapors during the first 1,000 miles of driving. Once the motor has been flown for a few dozen flights, the varnish vapors will disappear.
  • Can I perform the motor maintenance at my location, or does it require sending this in to KDE Direct for inspection?

    • Yes! All KDE Direct UAS Brushless Motors are designed to be field serviceable and a detailed, instructional video is provided in the Technical Videos section of the Technical Support Center.  Direct Video Link (YouTube). Please review the video for step-by-step instructions on how to replace bearings and shafts (full disassembly/reassembly) and Bearing and Shaft Replacement Kits are available for purchase.
  • Are the KDE Direct COAX motors available for purchase?

    • KDE Direct is continually leading the industry in new technologies and innovations, and the coaxial-motor is one such product brought to the world in 2016. These motors are custom-designed for various heavy-lift and commercial applications, and can be produced for your specific requirements (such as for the Shotover U1 system). Please review the Custom Products and Design Inquiries webpage for additional information on KDE Direct’s capabilities for your production needs.
