ORBIT SG Series

The ORBIT SG Series comprises ultra-rugged BLDC outrunner starter-generators designed for integration into unmanned systems and aerospace platforms requiring compact, efficient electrical power generation. Each unit is engineered with an ultra-lightweight housing that has been mechanically reinforced to withstand high shock and vibration environments typically encountered in airborne and field-deployed systems. Wear-free position sensing and integrated temperature monitoring support stable operation and reduced maintenance demands across extended service intervals.

Covering a wide performance range from low-power compact variants through to higher-output configurations, the series supports output levels from 250 W up to 10 kW depending on model selection. All variants operate within a common RPM band, enabling consistent mechanical integration across different engine sizes while maintaining scalable power delivery. The architecture is optimized for dual-role operation as both motor starter and generator, supporting flexible deployment in distributed power systems for unmanned and aerospace use cases.
