Products Description
Allen-Bradley 1326AB-B515G-21 Rotary Servo Motor Unit

Module Feature
1326AB-B515G-21 belongs to 1326AB Torque Plus series brushless AC servo motor manufactured by Allen-Bradley (Rockwell Automation). Rated power 2.9kW,149mm flange frame,max speed 5000RPM. It adopts resolver for position and speed feedback,offers high vibration resistance in harsh industrial environments. IEC metric flange with keyway solid shaft design. Widely applied in metal forming,packaging machinery,automation production lines and heavy-duty material handling equipment.
Working principle
Three-phase variable frequency AC power drives permanent magnet rotor to rotate. Resolver captures real-time position and velocity signals and sends feedback to Allen-Bradley 1391/1394 servo drive to realize closed-loop torque,speed and position control. Rare-earth magnet rotor delivers stable high continuous torque output.
Onboard components
Permanent magnet rotor,stator winding,rotor resolver,terminal connectors,keyed solid shaft,aluminum alloy metal housing,PTC temperature sensor.
LED indicators
Status indicators on drive side for position and fault monitoring.
Hardware self-diagnosis
Resolver signal integrity detection,motor winding insulation resistance check,over-temperature monitoring,over-current and short-circuit protection.
Programming software
Rockwell Motion Analyzer software,supports motor parameter auto-tune,real-time speed/torque monitoring and fault log reading.
