The R911293885 (MHD115A-058-NG1-BA) is a Bosch Rexroth servo motor from the MHD series, featuring a four pole pair, 115-size frame with an 'A' motor length, 192 mm flange, and 180 mm centering diameter. It uses a plain shaft with sealing and provides a holding brake torque of 70 Nm. The motor operates by natural convection cooling, supports digital servo feedback (HSF) for relative position detection, and is capable of continuous standstill torque of 32 Nm. Rated for characteristic speeds up to 4000 rpm and maximum speeds of 6000 rpm, it delivers a maximum theoretical torque of 110 Nm and incorporates Class F insulation. Operating temperature is specified for 0–40°C and installation at altitudes below 1000 meters above sea level. The power connection is located on side B via a standard output connector. Winding code for this model is 058.

Frequently Asked Questions

How does a holding brake with 70 Nm torque improve operational safety?

The brake ensures the load remains fixed when power is removed. The strong torque provides stability during vertical or precision positioning applications.

Why is a digital servo feedback encoder with relative position detection important?

The encoder supplies precise speed and position data to the drive. The feedback enables accurate motion control and quick response to positional errors.

How does a continuous torque of 32 Nm at standstill affect motor performance?

The torque ensures strong holding power even without rotation. The capability supports consistent force output for applications like robotics and presses.

What installation benefits come from a plain shaft design?

The shaft simplifies coupling with external gears or loads. The direct connection reduces mechanical complexity and enhances alignment accuracy.

How does the flange and centering diameter influence mounting accuracy?

The large centering diameter provides stable alignment with the driven machine. The design minimizes vibration and enhances mechanical balance during operation.
