• Resolver position feedback, stable against electromagnetic interference
• 460VAC three-phase power supply, suitable for industrial power grids
• IEC metric flange mounting with keyed shaft
• Robust sealed housing for workshop industrial environment
• Low cogging torque for smooth velocity and positioning control
• Compatible with matching 1394 digital servo drive system
• Original obsolete model, reliable spare for old production lines

Application Scenarios

• Automated assembly lines and material handling equipment
• CNC machine tools, gantry systems and multi-axis positioning stations
• Packaging, printing and textile machinery motion axes
• Automotive manufacturing robotic and transfer equipment
• Legacy Rockwell 1394 servo system retrofit and spare replacement
• Continuous process machinery requiring high precision speed control

FAQ

Q1: What feedback type does this motor use?

A1: It uses resolver feedback instead of optical encoder, strong anti-interference capability.

Q2: Which drive does it match?

A2: It is designed for Allen‑Bradley 1394 series digital servo drives.

Q3: Is this model still in production?

A3: No, this series has been discontinued by Rockwell, only spare and refurbished units available.

Q4: Can it be replaced with 1326AB-B520E variants directly?

A4: Need to verify shaft, flange, feedback and winding parameters before substitution.

Q5: What is the working voltage?

A5: Rated for 460V three-phase AC industrial supply.
