Product Description:1326AB-B4100-21-K4
The 1326AB Torque Plus Series Servomotors are an addition to the popular 1326AB Servomotor line. The Torque Plus motors feature a specially engineered housing to provide reduced length and increased torque ratings from 2.7 to 56.5 N-m (24 to 500 lb-in.). These high performance, three-phase, brushless, AC, synchronous servomotors are designed by Allen-Bradley to meet the stringent requirements of high performance motion systems. This series of AC servomotors is intended to be used with the Allen-Bradley 1391 Digital (1391–DES) AC Servo Drive (230V AC input). The typical speed-torque curve shows the operational envelope of different 1326AB Torque Plus/1391–DES drive combination
Features:1326AB-B4100-21-K4
- Special flux profile permanent magnets engineered by Allen-Bradley that provide increased servo response.
- A three-phase, sinusoidally wound stator field for direct transfer of heat to ambient temperature, and smooth operation at low speeds.
- A brushless resolver supplies position, commutation and velocity feedback information. This also provides durability in harsh environments as on-board electronics in the motor. 1391 A Quad B (optional) encoder output (adjustable from 512 to 2048 ppr) is generated via resolver feedback.
- 100% continuous rated output torque at stall .
- A precision balance of 0.0127 mm (0.0005 in.) total peak–to–peak displacement.
- A UL Listed insulation system .
- The ability to be vertically mounted at any angle with the shaft up or down.
- TENV construction. The aluminum housing has fins that provide increased heat transfer.
- IEC 529 enclosure protection IP65 (when used with the Shaft Seal option) to withstand harsh environments. The motor is dust-tight and able to withstand pulsating water jets.

• Integral spring-set holding brakes with 90V DC (–A4,–A5, –A7) or 24V DC coils (–K4, –K5, –K7). A Power supply (1326–MOD–BPS) is available for 90V DC brakes.
• A Shaft Oil Seal kit, (1326AB-MOD-SSV-xx) for installing a Viton shaft oil seal on a motor in the field. Motor disassembly is not required. When the shaft oil seal is installed, the motor is dust tight, able to withstand pulsating water jets and meets the IP65 requirements of the IEC 529 standard
Junction box kit (1326AB-MOD-RJxx) available with axially mounted connectors. Connector version allows the motor connectors to be brought out axially to the motor (rather than radially) without further wiring.
• Secondary feedback mounting kits (1326AB-MOD-Mxx) for field installation of an Allen-Bradley Encoder (845H).
Cables for power (1326-CPx...), commutation (1326-CFx... ), and encoders (1326-CEx...) are available in lengths up to 100 ft (30m) for standard and high-flex applications. Power (1326ES–CPxx...) and communication (1326ES–CFx...) cables between 100 ft (30m), and 300 ft (90m) are available when using a 1391–DES drive only

Applications:1326AB-B4100-21-K4
Tc – Rated torque of motor with windings at rated temperature and an ambient temperature of 40° C.
Tp – The peak torque that can be produced by the motor/drive combination with both at rated temperature. Higher peak torques are permissible where RMS torque is less than or equal to the rated torque (Tc).
Rated Speed – The operating speed of the drive and motor combination at which a minimum of 70% of continuous rated torque (Tc) can be developed. This point is defined with the motor at 25° C.
Rated Operation Area – Boundary of speed-torque curve where the motor and controller combination may operate on a servo basis without exceeding the RMS rating of either

Electrical Time Constant – Time required for the motor to reach 63% of its rated current. Max. Ambient Temperature – Maximum environmental temperature in which the motor can be operated at rated loads without exceeding its insulation–type temperature rise limits. Insulation Class – Designation of the operating temperature limits for motor insulation materials. Thermal Time Constant – Time required for motor windings to reach 63% of continuous temperature rise with constant watts loss. Torque Constant – Amount of torque developed for one ampere of motor current at the stated motor temperature. Voltage Constant – Value of the generated voltage at a specified speed when the rotor is moved mechanically in the magnetic field. Terminal Resistance – Winding resistance. Inductance – Winding inductance measured by a step input of zero impedance voltage applied to the locked rotor. Rotor Polar Moment of Inertia – Moment of inertia about the axis of rotation. Motor Weight – Weight of the complete motor (including brake, if supplied) less the weight of options. Balance – Compensation of rotor weight distribution to reduce vibrational resonance. Motors are factory balanced under running speeds.
