AB Rockwell's (Allen-Bradley) 1326AB-B420E-21 servo motor is a high-performance, three-phase brushless AC synchronous motor designed to meet the demanding requirements of servo system applications. The following is a detailed analysis of the servo motor:

1. Basic characteristics

Model: 1326AB-B420E-21

Type: High performance three-phase brushless AC synchronous motor

Brand: Allen-Bradley (Rockwell)

Second, technical characteristics

Permanent magnet rotor: The permanent magnet rotor design helps to improve the servo response speed and accuracy.

Three-phase sinusoidal winding stator magnetic field: The stator magnetic field is designed with three-phase sinusoidal winding, which can transfer heat directly to the environment, ensuring that the motor can run smoothly at low speeds.

Brushless rotary transformer: Provides position, commutation and speed feedback to make the motor durable in harsh environments.

High-precision output: 100% continuous rated output torque at stall (zero RPM), and the motor has a precision balance with a peak-to-peak total displacement of only 0.0005 inches (0.0127 mm).

Multiple installation modes: Vertical axis upward or downward installation to meet different application scenarios.

Third, protection and connection

Protection class: IP65 (when used with shaft seal options), the motor is dustproof and can withstand pulsed water flow, ensuring stable operation in harsh environments. However, it should be noted that when using externally mounted encoder/resolution feedback or blower kits, the motor will lose its IP65 protection rating.

Cables and connectors: Environmentally sealed power and feedback cable packages available in standard (flexible), rail (multi-flexible) or extended (ES) orders. The standard MIL connector ensures the reliability and stability of the connection.

4. Options and extensions

The 1326AB-B420E-21 servo motor also offers a variety of options and extended functions to meet the needs of different users. These options include:

Brake: Integral spring fixed brake with 90V DC coil or 24V DC coil.

Brake power supply: The voltage required to convert 115 volts AC to 90 volts DC brake.

Shaft oil seal kit: For field installation of fluororubber shaft seals without motor disassembly.

Mounting and feedback components: NEMA Imperial or IEC metric flange mounting options with metric shafts; Rotary transformer feedback components provide absolute/vernier or single brushless rotary transformer feedback; Junction box kits provide axially mounted connectors; Secondary feedback mounting kit for field installation of Allen-Bradley encoders or rotary transformers.

Cooling Kit: The blower cooling kit provides air cooling to the motor and increases torque output by up to 35%.

5. Application and compatibility

Application: The servo motor is widely used in CNC machinery, metallurgy, oil and gas, petrochemical, chemical, paper printing, textile printing and dyeing, machinery, electronic manufacturing, automobile manufacturing and other industries.

Compatibility: Used in conjunction with Allen-Bradley's 1391 AC servo controller for highly accurate motion control.

Six, precautions

When using externally mounted encoder/resolution feedback or blower kits, be aware that the motor will lose its IP65 protection rating.

When selecting and installing options, configure them according to actual application scenarios and requirements to ensure the best performance and stability of the motor.
