The R911274054 (MHD041B-144-PG1-UN) is a Bosch Rexroth synchronous AC servo motor intended for primary drive applications in automated systems. It features a brushless design, plain shaft with shaft seal, and a fully sealed housing with IP65 protection. The motor utilizes convection cooling, with a centering diameter of 50 mm, flange size of 82 mm, and a B-length 041 frame. Key specifications include a holding brake with 2.2 Nm torque, continuous torque at standstill of 2.7 Nm, and maximum continuous current of 7.5 A. Position feedback is provided by an integrated digital absolute encoder (>4096 revolutions). Power and feedback connections are supported via rotary connectors, adjustable within 270°. Electronic commutation enables high dynamic performance, repeated start-stop operation, and a wide speed range. The motor is suitable for mounting in any orientation and is equipped with overload temperature monitoring.

Frequently Asked Questions

What installation flexibility does the MHD041B-144-PG1-UN offer in tight spaces?

The connectors can rotate within 270°, making cable routing easier. This minimizes interference in compact machine layouts.

How does the integrated encoder impact precision in closed-loop systems?

It enables absolute position detection across multiple revolutions. This improves repeatability and reduces homing cycles at startup.

How is the continuous torque at standstill useful in automation tasks?

It allows the motor to hold loads without motion while maintaining accuracy. This is beneficial in clamping, pressing, or fine positioning operations.

What is the practical advantage of IP65 protection in factory environments?

It ensures safe operation even with dust and occasional water exposure. This makes it reliable in harsher industrial settings without additional housing.

How does the flange and centering diameter affect mechanical integration?

They define how easily the motor mounts into existing frames. Proper fit reduces alignment errors and improves drivetrain efficiency.
