This module is manufactured by Allen Bradley; it has a 5000 RPM maximum operating speed and a 194 millimeter Frame Diameter. It also has a 31.8 N-m system continuous Torque and an 11.7-Kilowatt motor rated output. It comes with an IEC Metric Flange with a Keyway Shaft and is rated for an IP65 enclosure, meaning that it is protected from water. The 1326AB-B720F-21K7 has environmentally secured cable package for power and feedback. It has an inch combination flange with a keyway for mounting and shafting; this motor has been specially manufactured in a compact size to reduce the motor length and to enhance continuous torque ratings.



The 1326AB-B720F-21K7 has been created for industrial use only. It has passed different standard certifications; it has a three-phase sinusoidal wound stator field to directly transfer of heat for smooth and consistent operation at lower speeds. Ferrite magnets are used for cost-effective performance. It comes with a brushless resolver which provides feedback information on position, commutation & velocity. It also helps provide durability in harsh environmental conditions, high operating temperatures and vibration by not having an onboard electronic device. For secure couplings, threaded holes are present on the face of the shaft. At almost zero RPM, it has a 100% continuous rated output torque and a precision balance of 0.0005 inches with a total peak displacement.

Texnite provided a power supply module which saved our NYC power plant customer from an emergency outage. We placed our order late in the afternoon. Even though it was well past their same day shipping cutoff time, Texnite still made an extra effort to ship our order immediately and the module arrived before 8am the following morning.
