The GE FANUC A06B-2078-B503 is a BiS 12/3000 AC servo motor developed for precision industrial motion applications. It combines a compact motor structure with integrated feedback and braking components, making it suitable for compatible FANUC CNC and automation systems.
Unlike a basic industrial motor, this servo unit is designed to operate as part of a coordinated motion control system. Its encoder provides position feedback, while the holding brake helps maintain shaft position when required.
The motor incorporates several important functional elements:
The A06B-2078-B503 belongs to the BiS 12/3000 motor family. Its configuration is intended to support precise motion control and stable operation in automated equipment.
