Inrunner BLDC Motors for drones & UAV

Our inrunner BLDC motor series includes the NOVA and ADVANCE families. The NOVA series features a robust closed-case design,available in power ranges from 1 kW to 50 kW. The ADVANCE series, on the other hand, has a lightweight open-case design, with power options from 1 kW to 5 kW.

Our inrunners are designed for durability and can achieve protection ratings of up to IP67, making them perfect for extreme environments, including snow, deserts, and marine operations.

Our inrunner motors achieve high torque density through the use of a high number of poles (up to 70) and a specialized magnetic system design. This allows for the reduction or elimination of gearboxes in many applications, considerably lowering system costs and weight.

Redundant Motor Solutions

Custom BLDC Drone Motors with Redundancy Features

Based on our established NOVA inrunner motors,the Nova X series has been designed to meet the needs of drone OEMs for safe and certifiable propulsion solutions. Featuring up to three redundant windings powered by independent ESCs,these high-reliability motors allow UAVs to execute safe emergency landings even if one ESC fails and a winding segment is compromised.

All NOVA X-Series motors can be customized to meet specific user requirements, offering a variety of options for thermal design, ingress protection up to IP67, winding configurations, pole counts, and more.

Electronic Speed Controllers (ESCs)

High-performance ESCs for Unmanned Systems

We highly recommend utilizing our motors and ESCs as a cohesive system for optimal performance; using products from different manufacturers can compromise efficiency,weight,and size advantages. Our engineering team is available to assist you in designing the ideal ESC solution and support you with system integration, including ESC configuration, optimal power supply, and thermal management.

For more information: Drone & UAV ESCs

Our systems are available as external generators (seperate from the combustion engine), attachment kits (to be mounted on the combustion engine), or integration kits (to be incorporated into the combustion engine housing). Our generators are compatible with boxer engines, inline engines, and single-cylinder engines ranging from 100-650 cm³.

accessories

The Plettenberg Gold Plug series was specifically designed for UAV applications.Unlike competing products made from steel, we manufacture the Gold Plug from aluminum with a gold coating, reducing weight by 50% and potentially saving over 120 g in a single UAV application. The Gold Plug features a unique design that prevents loosening due to shocks or vibrations, making it ideal for harsh environments. It also allows for frequent plugging and soldering without compromising the clamping force.
