The R911306075 (MHD112D-027-PG0-RN) is a synchronous servo motor designed by Bosch Rexroth, featuring liquid cooling and a plain shaft with integrated shaft seal. Rated for continuous standstill torque of 48.0 Nm and a maximum speed of 3000 RPM, it delivers a torque constant of 1.7 Nm/A and a voltage constant of 154.5 V/1000min-1, with a peak current draw of 142.2 A and a standstill current of 47.4 A under natural cooling. The motor has a motor size of 112, a flange size of 192 mm, and a centering diameter of 130 mm. It uses digital servo feedback with an absolute multiturn encoder capable of position detection over more than 4096 revolutions. The motor operates within 0 to 40 °C, with transport/storage temperatures permissible from -20 to +80 °C, and is designed for mounting at up to 1000 m altitude. The housing is rated IP68 with class F insulation. The power connector is oriented to the right side of the housing. No holding brake is included.

Frequently Asked Questions

How does ambient temperature influence motor efficiency?

The motor operates efficiently between 0 °C and 40 °C ambient temperature. The temperature range maintains insulation integrity and minimizes thermal drift in sensitive feedback elements.

What effect does installation altitude have on cooling?

The motor is rated for installation up to 1000 m above sea level. The limited altitude ensures sufficient air density for reliable natural convection cooling.

How does humidity exposure affect motor lifespan?

The controlled humidity environment prevents moisture absorption into winding insulation and bearings. The maintained dryness ensures consistent dielectric strength and reduces corrosion over time.

Why is the IP65 protection rating critical here?

The IP65 rating protects the housing against dust and low-pressure water jets. The sealed construction ensures consistent torque performance even in washdown industrial zones.

How do vibration levels influence operational stability?

The rated vibration tolerance preserves rotor alignment and bearing load balance during dynamic conditions. The stable structure ensures long-term reliability in automated assembly or machining systems.
