1326AB-A3E-11-A4

The Allen-Bradley 1326AB-A3E-11-A4 is an advanced AC motor. It belongs to the 1326AB family of servomotors. 1326AB servomotors are high-performance motors based on a brushless AC synchronous design. These servo motors are compatible with Allen-Bradley 1391 AC servo controllers. Standard features include a magnet rotor (with permanent magnet), 100% of rated torque at zero RPM (stall), a 3-phase sinusoidal stator field, sealed power/feedback cables, MIL-spec connectors, and it is IP65 rated.

The 1326AB-A3E-11-A4 is rated at 3000 RPM and 1.2 kW. The rating for the output when it is used with the 1391B-ES/1391-DES is 4000 RPM and 1.6 kW. The rated continuous stall torque (at 40 °C) is 48 lb-in (5.4 N-m). The rated maximum stall torque is 96 lb-in (10.85 N-m) which increases to 144 lb-in (16.3 N-m) when used with the 1391B-ES/1391-DES. The rated continuous stall current is 7.8 A, and the rated maximum stall current is 15.6 A which increases to 23.4 A when used with the 1391B-ES/1391-DES. The 1326AB-A3E-11-A4 has a 108 mm frame diameter and a stack length 3. It comes with an inch combination face/flange with keyway. A 72 lb.-in. (8.1 N-m) holding brake with a 90V DC coil is included as standard. The 1326AB-A3E-11-A4 weighs 16.8 kg. It can provide rated output power up to maximum 40 °C (without derating). Insulation on the drive is as per Class H. The features available with the 1326AB-A3E-11-A4 include a shaft oil seal kit, a junction box kit, secondary feedback mounting kits for field installation, and the cables for power, commutation, and encoders that are available in lengths of up to 100 feet.
