Allen Bradley 1326AB-B730E-21

The Allen-Bradley Servo motor with catalog number 1326AB-B730E-21 belongs to the 460V Torque plus series AC servo motors. This servo motor product line, including the particular catalog number is compatible with Allen-Bradley servo drive such as Kinetix, 1394 and Ultra motion control systems.

This servo motor is a Ferrite AC servo motor in particular with 194mm frame diameter and 215 mm bolt center. It is delivered with a resolver feedback as standard. It may also be specified with accessories such as including of feedback packages, Oils seal kit, Motor Junction kit, among others.

The 1326AB-B730E-21 features a dual operating speed based on the supplied voltage to the armature. If supplied with 460 VAC, the motor’s expecting speed is 3350 rpm while 2800 rpm for a 380VAC supply. With such input voltage supply, the motor also produces a power output of 6.8 KW along a rated Torque of 30.9 N-m. This servo motor is compatible for Two (2) types of axis modules. Depending on the axis module used, the motor’s rotor inertia, system continuous torque, peak stall and continuous stall torque varies accordingly. The specific compatible axis modules for this motor are AM07, AM50 and AM75.

It is important that this servo motor is mounted properly to deliver the expected results. Installation is critical for this type of equipment. As this motor is rated IP65, use of externally mounted accessories may void the inherent protection rating. With this, proper external protection must be applied. Additionally, the bolt size is also important to secure the motor in its location. It is specifically recommended to use M12 bolt with pitch of 1.75 mm (0.069 in.). The Flange thickness of this servo motor is 20.60 mm (0.811 in.), it is recommended to use a screw with length of 40 mm (1.57 in.).

The 1326AB-B730E-21 servo motor is a synchronous 1326AB series servo motor from Allen-Bradley. This series of motors can deliver a wide torque range from 2.7 to 50 N-m which may be used with Allen-Bradley Kinetix 6000 and 1394 motion control systems and the Ultra family of drives. Applications for the 1326AB-B730E-21 servo motor include automotive, packaging and machine tool applications. The 1326AB-B730E-21 servo motor operates at an input voltage of either 460 Volts AC or 380 Volts AC. The motor speed at 460 Volts AC is 3350 RPM and at 380 Volts AC, it is 2800 RPM. The motor output power and torque are 9.6 kilowatts and 39 N-m, respectively. When the 1326AB-B730E-21 servo motor is used with an Allen-Bradley AM50 axis module, the rotor inertia is 0.032 kg-m2, the continuous and peak stall torque are 39 N-m and 56.8 N-m, respectively, and the continuous and peak stall current are 22.8 Amps and 33.2 Amps, respectively. When the 1326AB-B730E-21 servo motor is used with an Allen-Bradley AM75 axis module, the rotor inertia is 0.22 kg-m2, the continuous and peak stall torques are 39 N-m and 85.4 N-m, and the continuous and peak stall current are 22.8 Amps and 50 Amps. The 1326AB-B730E-21 has 0.4 Ohms of winding resistance at 25 degrees Celsius, with 6.42 mH of phase-to-phase winding inductance, and it has mechanical and electrical time constants of 6.8 milliseconds and 16.1 milliseconds, respectively, at 25 degrees Celsius. The frame diameter for the 1326AB-B730E-21 servo motor is 194 millimeters (with a 215-millimeter bolt center) and 30 millimeters is the magnet stack length. The servo motor comes with integrated 41 N-m (140 pounds on an inch) holding brake with a 24 Volts DC coil made for the Allen-Bradley 1326AB-B7 frame series with an IP 67 protection rating. Also provided on the motor are a resolver-based feedback encoder and an IEC metric flange with keyway. The weight of the 1326AB-B730E-21 servo motor is approximately 62.6 kilograms. The motor should not be operated at ambient temperatures exceeding 40 degrees Celsius. The servo motor has dimensions of 514.9 x 173.6 x 207.5 millimeters, and it has a net weight of 62.7 kilograms.
