The NOVA 15 Light-Weight (“LW”) is from our family of super rugged inrunner BLDC motors and has been specifically designed for UAS and aerospace applications.

The rugged closed housing with IP 54 in standard (higher possible) allows for use in the harshest environmental conditions, such as desert, snow and marine missions. Compared to open outrunner BLDC motors, it offers extended MTBS/F with significantly reduced total cost of ownership. At the same time, the motor has been designed to be “light-weight”, as the name LW suggests. The NOVA 15 LW offers the best power-to-weight-to-robustness ratio in its class.

The NOVA 15 LW is available as COTS (commercial-off-the-shelf) version in various standard configurations. Please refer to the COTS datasheets under resources (below) for more information.

The motor can also be provided as MOTS (modified-off-the-shelf) or as FC (fully custom) version. The MOTS version is provided with custom winding, while FC versions can be highly tailored according to requirements (e.g. tailored housing and shaft, custom cooling system, added redundancy, higher IP rating, MIL-STD, etc.).

  • Super robust design for use in harsh environments
  • Standard protection class IP 54 (higher class possible)
  • Weight optimized housing, designed for UAV and aerospace applications
  • Best power-to-weight-to-robustness ratio in its class
  • Three hall effect sensors and one temperature sensor included in standard
  • Low moment of inertia with high efficiency in dynamic applications such as multi-copters
  • High torque density
  • Very smooth running
  • Only aerospace grade materials with highest quality are used
  • No need for gear boxes in most applications

Our support does not stop with selecting the best motor. We also provide propulsion design and system integration support. Our experienced engineers help in the initial propulsion design phase of the UAV, support in selecting the ideal prop and motor coupling (together with our partner Mejzlik) as well as selecting the best ESC. We also provide custom thermal concepts, with active or passive fans, air ducts and tailored fins. When combining our motors with one of our high-performance ESCs, we can also offer fully integrated units (motor and ESC as single replaceable unit) as well as additional features such as prop homing functions.
