The R911274053 (MHD041B-144-PG0-UN) is a Bosch Rexroth Indramat MHD041B series synchronous servo motor, designed for low-torque motion control applications. It is available in 60K and 100K windings, providing rated torques of 1.4 Nm at 3,000 RPM (0.52 kW) and 1.5 Nm at 4,500 RPM (0.88 kW), respectively. The motor features a plain shaft with a shaft seal, 82 mm flange, 50 mm centering diameter, and B motor length. The encoder system utilizes a digital servo feedback with an absolute position capability exceeding 4096 revolutions. It employs natural convective air cooling, has an IP65 protection rating, and supports a turnable power connection within a 270° range.

Frequently Asked Questions

How does absolute position detection benefit motion control applications?

It eliminates the need for homing sequences on startup, saving time in automated cycles. This is particularly important in continuous production lines and robotics.

In which applications is a continuous standstill torque of 2.7 Nm most relevant?

It is ideal for maintaining load positions during precise machining or controlled pauses. Such torque capacity supports smooth holding in CNC milling, packaging, or pick-and-place machines.

What practical advantage does a plain shaft design offer?

It allows for flexible coupling with a wide variety of machine-side connections. Installers can adapt it to gears, pulleys, or direct-drive couplings depending on system requirements.

How does the compact B motor length affect mechanical integration?

A shorter motor body reduces the space needed in machine frames or enclosures. This makes it suitable for multi-axis systems with dense component layouts.

How does the 82 mm flange size influence compatibility with machine mounts?

It standardizes installation with industry-common mounting dimensions. This enables straightforward replacement or integration into modular machine designs.
