We design, develop and manufacture a wide range of high-performance outrunner BLDC motors. Our outrunner series is named ORBIT and 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 very powerful motors with high torque, but 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 as well as in other industrial sectors.

Our outrunners are very compact in design and have leading power-to-weight ratios.

Plettenberg offers its outrunner BLDC motors under three product categories: COTS, MOTS and FC. Our COTS (“commercial-off-the-shelf”) products are standard solutions in predetermined configurations, with shortened delivery times. If a COTS product is not suitable for the envisaged application, Plettenberg offers MOTS (“modified-off-the-shelf”) solutions. MOTS motors come with custom winding and electrical design support from our engineering team. If a MOTS solution is not sufficient and significant tailorization is required, a FC (“fully-custom”) solution can be offered. FC drive solutions are highly application specific and can be adjusted to complex requirements. From our experience, most projects start with a COTS or MOTS solution, and progress to a FC solution as first data has been gathered and requirements become more rigid.
