Plettenberg is a leading developer and manufacturer of tailored electric drive solutions for the unmanned systems market. We are the global leader in high-performance inrunner BLDC drone motors.

Our product range also includes outrunner BLDC motors, brushed DC motors, ESCs, generators and starters as well as related accessories. Our drive systems are unrivalled in their robustness, power-to-weight ratio, efficiency and compactness, making them suitable for heavy-duty professional and defense applications in harsh environments.

Electric Drone Motors

All our drive solutions are made-to-order and tailored to the specific requirements of our customers, such as adjustments to housing, shaft, number of poles, winding, cooling, IP rating, etc. These customizations allow us to build the most efficient solutions for your specific load profile. Our engineering team works hand-in-hand with you, to provide the required technical support and system integration advice.

Plettenberg manufactures all products in Germany and has a strict quality system which is ISO 9001 certified.

Inrunner BLDC Motors for Drones & UAV

Our inrunner BLDC motor series consist of the NOVA and the ADVANCE families. The NOVA family has a robust closed case design and is available in the power range from 1 kW to 50 kW. The ADVANCE family has a light-weight open case design and is available in the power range from 1 kW to 5 kW.

Our inrunners are very robust in design and available with protection class of up to IP67. This makes them ideally suited for application in harsh environments, such as snow, desert or sea operation.

For our inrunner motors, we achieve a high torque density by using high pole numbers (up to 70) and special design of the magnetic system. For most applications, the use of gear boxes can be mitigated, which reduces system cost and weight significantly.

Outrunner BLDC Motors

Our ORBIT series of outrunner motors is available in the power range from 1 kW to 15 kW. The heritage of our outrunners is in the model aircraft market, which required powerful high torque motors, at very low weight.

Over the years, we have advanced the design of our outrunners to make them suitable for application in the commercial and defense UAV sector. Our outrunner motors are extremely compact in design and have leading power-to-weight ratios.

Electronic Speed Controllers (ESCs)

High performance ESCs for unmanned systems

Plettenberg develops and manufactures a wide range of rugged high-performance ESCs, with the top models being able to handle voltage of up to 400 V and current of up to 250 A. All our drone ESCs are developed and manufactured at our HQ in Germany and built by hand according to highest quality standards. We can tailor the hardware and software of our ESCs to the specific use case and application requirements.

Drone Motor ESC

We highly recommend using our motors and ESCs as a combined system solution for optimal performance; the use of competing products can compromise the efficiency, weight and size advantages. Our engineering team will help you in designing the right ESC solution and support you in system integration, including ESC configuration, ideal power supply and thermal management.

Generators & Starter Systems

Engine starter systems for drones & UAV

Plettenberg designs and manufactures generators and starters as well as related electronics for combustion engines in unmanned system applications. We offer generators in the power range from 500 W to 15 kW.

Drone engine starter systems

Our systems are available as external generator (separate to combustion engine), attachment kits (to be attached to combustion engine) or as integration kits (to be integrated in combustion engine housing). Our generators can be used for boxer engines, inline engines and single-cylinder engines from 100-650 cm³.

Accessories

Plettenberg provides a wide range of high-quality, low-weight accessories. Our accessories are built according to the same quality and performance standards as our electric drone motors and ESCs. The product range includes the Gold Plug Series, programming sets, data loggers, cabling, capacitors and fuse boxes.

Drone engine components

The Plettenberg Gold Plug series was specifically developed for UAV applications. While competing products are made from steel, we produce the Gold Plug from aluminum with a gold cover, which saves 50% of weight and easily accumulates to more than 120 g in a single UAV application. The Gold Plug features a special design which prevents loosening from shocks or vibration, making it ideal for use in harsh environments. The Gold Plug also allows frequent plugging and soldering without affecting the clamping force.
