Allen Bradley 1326AB-B420E-21 Used Surplus

Manufactured by Allen-Bradley/Rockwell Automation, the 1326AB-B420E-21 servo motor is a medium inertia brushless servo motor. The motor belongs to the Allen-Bradley 1326AB servo motor series and it uses 380 to 460 Volts AC input power with a 108-millimeter diameter frame or 115-millimeter bolt center diameter. This servo motor has a magnet stack length of 20, with a motor rated speed of 2500 RPM at 380 Volts AC input voltage and 3000 RPM at 460 Volts AC input voltage. It also has a rated torque of 5.0 N-m or 44 pounds on an inch, a peak torque of 14.9 N-m or 132 pounds on an inch, and a power rating of 1.1 kilowatts. The 1326AB-B420E-21 servo motor also has a system continuous stall current of 2.84 Amps. Additionally, the 1326AB-B420E-21 servo motor has an IEC metric flange with a key.

The entire 1326AB servo motor series, as well as the Allen-Bradley 1326AB-B420E-21 servo motors, are 3-phase brushless servo motors that offer high performance. These motors are designed to help meet strict servo system application needs. The 1326AB servo motors series are compatible and can be used with the 1391 AC servo controllers. Some of the main features of these motors include a permanent rotor to enhance the servo response, a 3-phase sinusoidal wound stator field that enables the direct transfer of heat and it also enhances smooth operations. When used with a shaft seal, the motors are IP 65 rated, allowing them to withstand harsh environments. They are also dust-tight and they can tolerate pulsating water sprays and prevent any liquids from entering inside the motor. Other features include ferrite magnets that provide cost-effective performance and standard MIL-spec connectors.
