1326AS-B330H-21-394

|

The 1326AS-B330H-21-394 servo motor is a brushless servo motor that operates at 460 Volts AC. It has been manufactured by Allen-Bradley/Rockwell Automation as a member of the Allen-Bradley Bulletin 1326 series of servo motors. The 1326AS-B330H-21-394 brushless servo motor has low inertia ratings because it comes with a 3-inch magnet stack made of rare-earth magnets that reduce its friction levels while it operates. Its approximate stator size is 75 millimeters. The 1326AS-B330H-21-394 brushless servo motor has an IP 65 waterproof and dustproof protection rating when an oil shaft seal is installed on it.

Manufactured by Allen-Bradley, the 1326AS-B330H-21-394 belongs to the 1326AS Series of motors. It runs on a voltage of 460 Volts AC, with a 75-millimeter frame diameter. This product features a rated motor speed of 6500 RPM. It contains a system continuous torque of 2.1 N-m with a motor rated output of 0.9 kilowatts. The Allen-Bradley 1326AS-B330H-21-394, as well as the entire 1326AS rare earth servo motors series, comes with a neodymium-iron-boron permanent magnet rotor designed and intended to offer low inertia, high peak torques, and high accelerations. The 1326AS-B330H-21-394 servo motor is compact, brushless, and environmentally-rugged. The product is planned for use with the Allen-Bradley 1394 Motion Control System. Other features of the 1326AS-B330H-21-394 servo motors and each of the 1326AS include an economical, compact design capable of functioning in severe settings. These motors have IP65 environmental ratings and they feature TENV construction. This product comes with a thermal switch in the motor winding which is usually closed (with 2.5 Amps at 250 Volts AC maximum current rating) for thermal overload indication.

Every servo motor in the 1326AS series, including the Allen-Bradley 1326AS-B330H-21-394 servo motor, features a rugged, two-pole brushless resolver offering accurate position feedback that helps in eliminating the need for onboard electronics. Additionally, this brushless resolver can endure harsh shocks, as well as high operating temperatures and vibrations. The resolver feedback produces up to 1024 ppr or 4096 counts/revolution A Quad B encoder output. The Allen-Bradley 1326 Servo Motors are made to offer optimal performance and high continuous output. They come in three different frame sizes as well as a full torque range ranging from 2.7 to 50 N-m. 1326AS-B330H-21-394 Servo Motors are intended for use with the Allen-Bradley 2098-HVs, Kinetix 6000, or 1394 motion control systems as well as for applications. These motors have a modern magnet design, comprising a magnetic flux orientation that increases flux density. The feature enhances demagnetization protection and also lowers harmonics as well as losses.
