Plettenberg is the global leader in high-performance inrunner BLDC motors for tactical drones, and provides solutions for hybrid VTOL, fixed-wing, single- and multirotor as well as loitering munition platforms.
Our product range also includes outrunner BLDC motors, brushed DC motors, ESCs, generators and starters as well as related accessories.
Plettenberg manufactures all products in Germany, adhering to a strict ISO 9001-certified quality system. All our drive solutions are made-to-order and customized to the unique needs of our customers, with engineering and system integration support provided every step of the way.
Inrunner BLDC Motors for Harsh Environments
We provide robust open- and closed-case inrunner BLDC motors available in a wide range of configurations and power ranges. With ingress protection up to IP67, they are ideal for challenging conditions such as snow, deserts and seawater environments. Available in the power range from below 1 kW to 50 kW.
Outrunner BLDC Motors for SWaP Restricted Applications
Our outrunner brushless DC motors are designed for airborne platforms with high-torque, low-weight requirements. With an extremely compact design and leading power-to-weight ratios, they are ideal for SWaP (size, weight and power)-restricted applications. Available in the power range from below 1 kW to 15 kW.
Ruggedized Brushed DC Motors
Our highly durable brushed motors feature a special hand-wound design and provide low resistance, excellent running characteristics, and leading power-to-weight ratios. The unique construction allows for easy and convenient exchange of brushes. Available in the power range from below 500 W to 1500 W.
Rugged Electronic Speed Controllers (ESCs)
Our rugged high-performance ESCs are available in a wide range of powers. Our top ESCs can handle voltages of up to 400 V and currents of up to 350 A. They are ideal for pairing with our motors, providing a combined solution engineered under one roof for optimal performance.
Generators & Starter Systems
Plettenberg's generators and starters are ideal for a wide range of military UAV combustion engines, and 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).
