About
Beyond Gravity offers a low-cost actuator (LA) optimized for minimal manufacturing and assembly costs. It features high unpowered detent torque, allowing it to maintain the pointing position in an unpowered state even under high back-driving torques.
The LA15 low-cost actuator is a hybrid-type stepper motor with high detent torque, a planetary gear, and high-load output bearings. It is based on the Beyond Gravity modular actuator system, which allows the full range of motors and gears in the system to be exploited to meet specific requirements.
The LA15 low-cost actuator will be used in Beyond Gravity electric propulsion pointing (EPPM) mechanisms. Electric propulsion pointing mechanisms require actuators that are lightweight, precise, and reliable.
