Product Description
The Allen-Bradley 1326ABB730E-21-K7L Torque Plus Servo Motor is a high-performance 3-phase brushless AC synchronous motor with a permanent magnet rotor, designed for demanding industrial servo applications. It features a resolver for communication and velocity feedback, a sine-coded wound stator for smooth operation, and delivers 100% torque at stall. Operating at 380-460 VAC (nominal 460 VAC), it offers a maximum 9.6 kW output power, a stall current of 22.8 A (peaking at 50.0 A), and a rated rotor speed of 2800 RPM (380 VAC) or 3350 RPM (460 VAC). The motor provides a rated torque of 39.0 N-m, a peak stall torque of 85.4 N-m, and has a rotor inertia of 0.024 Kg-m2. It exhibits a 9.6 ms mechanical and 11.92 ms electrical time constant, a 60-minute thermal constant, and Class H insulation. With a winding resistance of 0.426 Ohms, a winding voltage of 126.2 V/1000 RPM, and a winding torque of 2.01 N-m, this motor includes a resolver for accurate position feedback, an optional 24 VDC holding brake (41 N-m torque), an IP67-rated enclosure, a 194 mm frame diameter, a 30 mm stack length, an IEC-rated flanged mounting with keyway, and weighs 62.6 kg (with brake), with dimensions of 207.5 x 514.7 x 173.6 mm.
Is Your Device Showing These Signs?
The Allen Bradley 1326ABB730E-21-K7L servo motor commonly exhibits issues such as resolver signal degradation, requiring resolver replacement or recalibration. Winding insulation breakdown leads to shorts and ground faults, necessitating motor rewinding or replacement. Bearing failure, indicated by excessive noise and vibration, demands bearing replacement and shaft inspection. Encoder malfunction results in inaccurate positioning and velocity feedback, mandating encoder repair or replacement. Connector pin corrosion and cable damage cause intermittent communication and power delivery problems, requiring connector cleaning/replacement and cable repair/replacement.
