Allen Bradley 1326AB-B420H-21-L Used Surplus

The Allen-Bradley 1326AB-B420H-21-L servo motor runs on a voltage of 460/380V AC. It has a frame diameter of 108 mm and a rated motor speed 6000 rpm. It also has an IEC metric flange with a keyway flange and shaft series. This servo motor has motor rated torque of 5.1 Nm, a motor rated output of 2.2 kW, a system continuous torque of 5.1 Nm, and a System Peak Stall Torque of 14.0 Nm. It also has an IP67 environmental rating as its standard option.

The 1326AB-B420H-21-L servo motor has motor junction box kit which helps in providing axially-mounted connectors with either rear exit connections or front exit connections. The junction box also enables the motor connectors to be axially brought out without further wiring to the motor. The 1326AB-B420H-21-L servo motor also features encoder mounting adapters. These adapters are not available for motors which have high-resolution feedback. When mounting servo encoders to the adapter plate, servo clamps have to be used. Servo clamps can accommodate both metric servo and English servo encoder mounting configurations. After adapter installation, remove and discard the gasket during disassembly to avoid equipment damage that might be caused by the gasket.

The 1326AB-B420H-21-L servo motor features an integral holding brake option which is spring-set just when the power is removed. This disc-type brake has been specifically designed to provide limited braking torque for emergency stopping and to hold a load at rest. This brake should not be continuously cycled to assist in stopping a load or used as a positioning brake. The user should ensure that the brake is not energized/de-energized for more than 90 times within an hour when it is being used as a parking brake. The only purpose of the parking brake is to hold a stationary load and not to stop motor movement unless there is power interruption.
