* The Allen Bradley 1326AB-B740C-21-L has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B740C-21-L units instead of migration.
The 1326AB-B740C-21-L servo motor is a Torque Plus brushless AC servo motor manufactured by Allen-Bradley. At 460 Volts AC, the rated speed of this motor is 2000 revolutions per minute but that rating drops to 1800 revolutions per minute when the drive is used in 380 Volts AC rated applications. Its power rating is 8.7 kilowatts and its torque rating is 53 N-m. The advanced design of its magnets provides quicker acceleration and torque performance to meet different application needs. The 1326AB-B740C-21-L Torque Plus servo motor is intended for use with motion control systems in Allen-Bradley Kinetix 6000, Ultra 460 Volts (2098-HV) or 1394 devices. Its 3-phase, sinusoidal-wound stator field ensures seamless operation at low speeds while its square torque improves its torque performance in high-speed applications.
Applications that require smooth performance and high continuous output can benefit from the capabilities of the 1326AB-B740C-21-L servo motor. A factory-installed shaft seal is available on the 1326AB-B740C-21-L Torque Plus servo motor to match the IP 67 rating of the enclosure which protects the servo motor’s bearing in environments where the motor shaft may come in direct contact with liquids, dust, or debris. This motor can be used with accessories like a junction box kit and feedback devices, and it supports vertical mounting orientation. The 1326AB-B740C-21-L Torque Plus servo motor provides 100% continuous-rated output torque at 0 rpm. It offers a precise balance of 0.0127 millimeters of total peak-to-peak displacement and it features 2 thermal switches that are wired in series. The thermal switches open during excessive temperature conditions.
