Allen Bradley 1326AB-B740C-S2L

The 1326AB-B740C-S2L servo motor from Allen-Bradley is a high-performance servo motor that operates at 380 to 460 Volts AC input voltage. The product range to which this motor belongs is the 1326AB series which is designed with many advanced features including special permanent magnets, IP 65 rated motor enclosures which improve to IP 67 enclosures with shaft seal kit,s sinusoidal wound stator fields, support for vertical mounting at different angles, and IEC 72-1 metric flange mounting. Additionally, resolver or encoder-based feedback options are available. The 1326AB-B740C-S2L servo motor is a motor with a 40-millimeter magnet stack length and a frame length equaling 194 millimeters. The rated motor speeds are 1800 RPM and 2200 RPM at 380 Volts AC and 460 Volts AC, respectively.

The 1326AB-B740C-S2L servo motor comes with an integrated single-turn encoder for feedback. This high-resolution encoder provides accurate machine positions within 2 million counts per revolution and it can be used for applications that require very precise tolerance. The enclosure of the 1326AB-B740C-S2L servo motor is IP 67 rated and it comes with a shaft seal. The IP 67 rating means that the enclosure provides environmental protection against the effects of temporary water immersion. The weight of the 1326AB-B740C-S2L servo motor is approximately 77.1 kilograms. The rotor polar moment of inertia is 0.032 kg-m2. The thermal specifications include insulation Class H and 60 minutes of the thermal time constant. The environmental specifications include a maximum recommended ambient temperature of 40 degrees Celsius. The mechanical time constant for the motor is 6.1 milliseconds. The continuous and peak stall torque with the AM75 axis module are 53 N-m and 84.2 N-m, respectively. The peak stall current for the motor is 50 Amps with the AM75 axis module.
