The MHD112 Synchronous Motor, MPN R911294458 (MHD112B-035-NP0-BN), is designed with a keyed output shaft, IP65 protection rating, and class F insulation. It utilizes digital servo feedback (HSF) for precise speed and position control, operating at a nominal speed of 2500 RPM with a surface cooling current draw of 21.7 A. Maximum torque is 102 Nm and peak speed reaches 4000 RPM. The motor produces 8.0 kW at 294 V and 167 Hz under natural cooling (100 K). Continuous torque at standstill is 28 Nm at 26 A in 60 K normal cooling. Technical features include a centering diameter of 130 mm, flange size of 192 mm, winding resistance of 0.43 Ω at 20°C, winding inductivity of 5.5 mH, voltage constant of 108.5 V/1000min⁻¹, and moment of inertia at 192×10⁻⁴ kg·m². The unit is constructed without a holding brake, features a shaft seal, and is finished with a black paint coat.

Frequently Asked Questions

How does the keyed shaft with integrated seal enhance the motor’s durability?

The keyed shaft ensures secure torque transfer under dynamic loads. The integrated seal protects against dust and coolant ingress, extending the motor’s service life.

How does the winding code 035 influence motor efficiency?

The 035 winding code optimizes copper utilization, lowering resistive losses. This results in reduced energy consumption and improved long-term thermal performance.

What benefits does liquid cooling offer compared to air-cooled motors?

Liquid cooling removes heat more efficiently, allowing continuous operation under higher load conditions. It also minimizes fan noise and airborne contamination.

Can the MHD112B-035-NP0-BN be integrated with various drive controllers?

Yes, it’s compatible with a wide range of Rexroth and third-party drives. This flexibility supports modular automation setups and simplifies retrofitting.

How do flange size and centering diameter affect mounting compatibility?

A flange size of 192 mm and a 130 mm centering diameter follow standardized dimensions. This ensures seamless mechanical integration with existing industrial drive systems.
