* The Allen Bradley 1326AB-B420E-21-L has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B420E-21-L units instead of migration.
The 1326AB-B420E-21-L servo motor is a Torque Plus series ferrite AC servo motor manufactured by Allen-Bradley. The 1326AB-B420E-21-L servo motor offers high-performance speed and torque capabilities to meet the needs of different industrial applications. This brushless servo motor can be used in 460 Volts AC or 380 Volts AC rated Allen-Bradley 1394 motion systems. Its specifications are 1.1 kilowatts of output power, 5.0 N-m of rated torque, 14.9 N-m of peak torque, 3000 revolutions per minute at 460 Volts AC voltage, and 2500 revolutions per minute at 380 Volts AC voltage, 0.0008 N-m of rotor inertia, and 2.84 Amps of system continuous stall torque. This servo motor is ideal for applications like machine tool, material handling, automotive, converting, packaging, and metal forming applications.
The innovative magnet design of the 1326AB-B420E-21-L Torque Plus servo motor includes magnet flux orientation which increases flux density to improve demagnetization protection, lower harmonics, and to reduce losses. The high-voltage windings of this motor feature heavy-duty insulation material. This, combined with its heavy-duty cables and stator system combine to maintain stable operation throughout the run sequence of the motor. The diameter of its frame is 108 millimeters and the IP 67 protection rating of its housing allows for it to be used in harsh environments. The sinusoidal, 4-pole design of the 1326AB-B420E-21-L Torque Plus servo motor ensures predictable linear performance. Its square torque-speed feature provides increased torque performance at high speeds and the motor is compatible with high-resolution encoders. This motor supports vertical mounting regardless of the angle and the type of bolts for connecting it to the machine are 20-millimeter M8 bolts.
