The Bosch Rexroth R911290382 (MHD112D-027-NG0-RN) servo motor is part of the high-performing MHD product series. This innovative motor offers high reliability and no necessity for maintenance, functioning optimally even in harsh environmental conditions. It comes with electronic commutation and low inertial mass, and the inbuilt data memory ensures seamless and rapid startup. Its exterior is designed for both natural convection and surface cooling, offering varying continuous stall torque and current based on the cooling method and over-temperature. The main shaft incorporates a sealing ring and its power connector is located to the right of the housing, drawing power from a drive controller. The R911290382 (MHD112D-027-NG0-RN) can sustain a power cable cross-section subject to the cooling and over-temperature methods. This robust and reliable industrial motor weighs 56 kilograms.

Frequently Asked Questions

What defines the motor’s permissible ambient temperature range?

The permissible ambient temperature range is defined between 0°C and 40°C for optimal operation. The range ensures consistent performance without overheating or insulation degradation.

How does storage temperature affect motor reliability?

The storage temperature from –20°C to +80°C prevents condensation and component stress. The range allows safe transport and long-term storage under controlled conditions.

Why is maximum setup height limited to 1000 meters?

The maximum setup height of 1000 meters ensures sufficient air density for cooling. The limit maintains stable thermal performance and prevents insulation breakdown.

What is the impact of humidity on motor operation?

The motor operates best in non-condensing humidity conditions to prevent corrosion and electrical leakage. The insulation system is designed for dry and clean environments.

How does protection class IP65 support environmental durability?

The IP65 rating prevents dust ingress and protects against low-pressure water jets. The feature enables installation in demanding industrial settings with controlled exposure levels.
