SH31003P11A2000

Configured for servo torque and speed transmission in PacDrive 3 motion control systems, the Schneider Electric SH31003P11A2000 (SH3 servo motor) provides direct electromechanical motion through a three-phase motor winding and absolute single-turn SinCos Hiperface encoder. It has a parallel-key shaft, no holding brake, 6000 rpm maximum mechanical speed, and rotatable right-angled electrical connectors.

Motor Feedback and Mechanical Interface

The SH3 motor uses an absolute single-turn SinCos Hiperface encoder with a speed feedback resolution of 128 periods. The parallel-key shaft has a 19 mm diameter, 40 mm length, and 6 mm key width. The 100 mm flange uses four 9.0 mm mounting holes arranged on a 115 mm circle.

The motor has no holding brake. Mechanical load coupling therefore depends on the external machine braking or holding arrangement. Maximum specified axial force is 160 N, while permissible radial force varies with rotational speed.

Frequently Asked Questions

Q: What encoder is fitted to the SH31003P11A2000?

Q: Does this motor include a holding brake?
A: No. The supplied specification identifies the holding brake as without.

Q: What is the maximum mechanical speed?
A: The maximum mechanical speed is 6000 rpm.

Field Installation Guidelines

Mount the motor using the specified 100 mm flange and four mounting holes. Maintain the specified shaft alignment between the motor and driven mechanism to limit radial and axial loading.

Use the parallel-key shaft connection with a mechanically compatible coupling or hub. Do not exceed the stated radial and axial force limits, particularly at higher rotational speeds.

Connect the motor and encoder using the designated connectors. Route motor power conductors separately from encoder and other low-level feedback wiring where practical to reduce electromagnetic coupling. Bond cable shields according to the drive and machine grounding scheme.

The motor uses natural convection cooling. Provide sufficient clearance around the motor housing to prevent obstruction of heat dissipation. Verify the motor, drive, supply voltage, encoder interface, and mechanical load ratings before commissioning.
