Allen‑Bradley 1326AB-B530E-21-K5 Torque Plus AC Servo Motor

Product Brief Description

The Allen‑Bradley 1326AB-B530E-21-K5 is a 4.2kW permanent magnet brushless AC servo motor from the discontinued 1326AB Torque Plus series. It delivers 18 Nm continuous torque at 3000 RPM, equipped with resolver feedback and integrated 24VDC holding brake, IEC metric keyed flange, designed for use with Allen‑Bradley 1394 digital servo drives for high‑performance motion control and legacy equipment spare replacement.

Product Features

• 4.2kW rated power, 18 Nm continuous stall torque, peak torque up to 54.2 Nm
• Resolver position feedback, strong anti‑interference for noisy industrial sites
• Built‑in 13.6 Nm 24VDC holding brake for load retention during power loss
• 460V three‑phase AC rating, 149mm IEC metric flange with keyed shaft
• IP67 sealed housing, robust structure for heavy industrial environments
• Low cogging torque, smooth speed and positioning performance
• Optimized for Allen‑Bradley 1394 servo drive platform
• Obsolete original model, reliable spare for existing production line retrofits

Application Scenarios

• CNC machine tools, gantry systems and multi‑axis positioning equipment
• Automotive assembly lines, transfer machines and robotic material handling
• Packaging, printing, textile and metal forming machinery motion axes
• Heavy automation equipment requiring brake‑assisted load holding
• Legacy Rockwell 1394 motion system maintenance and spare replacement
• Continuous process machinery with high dynamic positioning requirements

FAQ

Q1: What feedback device does this motor use?

A1: It uses resolver feedback instead of optical encoder, better resistance to vibration and EMI.

Q2: Does it come with a holding brake?

A2: Yes, integrated 13.6 Nm holding brake with 24VDC coil for static load holding.

Q3: Which servo drive is compatible?

A3: It matches Allen‑Bradley 1394 series digital servo drives.

Q4: Is this motor still in production by Rockwell?

A4: No, this series is discontinued, only surplus and refurbished spare units available.

Q5: Can it directly replace 1326AB-B520F-21-K5?

A5: Torque, brake and shaft parameters differ; verify full specs before substitution.
