sAbout 1326AB-B730E-21MK7L
The 1326AB-B730E-21MK7L is a servo motor from Allen-Bradley/Rockwell Automation and it belongs to the 1326AB series of servo motors. The motor operates at an average voltage of 380 to 460 Volts AC. The 1326AB-B730E-21MK7L has a multi-turn high-resolution feedback device, a 41 N-m and a 24 Volts DC coil used with the holding brake. Additionally, the servo motor should be operated in environments that are IP67-rated. The “6” in “IP67” shows that the motor is protected from dust while the “7” indicates that the 1326AB-B730E-21MK7L is guarded against the damaging effects that may be caused by the motor being immersed in water in depths ranging from 15 centimeters to 1 meter. The IP67 specifications lose effect when an external junction box or an encoder is used.
The 1326AB-B730E-21MK7L, as with other servo motors with the B7 frame, uses the M12 bolt size, a 1.75-millimeter pitch, and a flange thickness of 20.60 millimeters and a screw length not exceeding 40 millimeters. The 1326AB-B730E-21MK7L is part of the three-phase AC high-performance servo motors product line manufactured by Allen-Bradley to be used with the 1394 motion control systems from Rockwell Automation. The multi-turn feature of the 1326AB-B730E-21MK7L prevents the machine from re-homing on every power-up by ensuring that machine positions (absolute) are provided over multiple revolutions without the need of a battery. The 1326AB-B730E-21MK7L AC servo motor has a rated speed of 3350 RPM at 460 Volts AC and 2800 RPM at 380 Volts AC and at 9.6 kilowatts of output power. When used with the 1394 system, an external encoder is eliminated since the A Quad B feedback output can be driven by the 1394 servo system directly from the motor feedback. The 1326AB-B730E-21MK7L has a rotor inertia of 0.024 kg-m2, a system continuous torque of 39.0 N-m, and a system peak stall torque of 56.8 N-m. Additionally, the 1326AB-B730E-21MK7L has a current (system continuous stall) of 22.8 Amps and a peak stall current (system) of 33.2 Amps.

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.
