Allen Bradley 1326AS-B310H-21-K3 Used Surplus

The Allen-Bradley 1326AS-B310H-21-K3 servo motor is a rare-earth AC servo motor constructed with a permanent magnet (neodymium-iron-boron) rotor. This device accelerates quickly and it is able to change direction dynamically. The 1326AS-B310H-21-K3 servo motor provides low inertia and it can handle high peak torques. It is designed to work in surroundings with ambient air temperatures between 0 and 40 degrees Celsius (32 and 104 degrees Fahrenheit). It is crucial to maintain the temperature between these extremes because this type of device heats up rapidly during operation. Do not touch the surface of the motor while it is operating because the aluminum housing can reach temperatures greater than 100 degrees Celsius.

The Allen-Bradley 1326AS-B310H-21-K3 servo motor has a nominal rotating speed of 6200 RPM. Its shipping weight is 2.8 kilograms (6.2 pounds). Beneath the housing, there are sub-assemblies like a rugged 2-pole brushless resolver rated at 4096 counts per revolution for accurate position information forwarding to an AC servo drive, a normally closed thermal switch for overheating prevention, and a spring-set holding brake with a 24 Volts DC rated coil. The brake system needs 0.5 Amps of current to activate the coil. The brake is activated almost instantly (38 milliseconds). It is not recommended to activate or deactivate the brake more than 90 times per hour. It is also recommended to activate the brake after the servo drive decelerates the motor to 0 rpm. Do not use it to stop the motor rotation completely. This is not an emergency stop type of brake. The 1326AS-B310H-21-K3 servo motor has impressive characteristics such as 6.1 pounds on an inch of continuous stall torque, 18 pounds on an inch of peak stall torque, 0.3 kW of motor rated output, and 0.000045 kg-m2 of rotor inertia.
