The R911295832 (MHD112B-035-PG1-AN) is a synchronous servo motor featuring digital feedback with an integrated multiturn encoder capable of absolute position detection beyond 4096 revolutions. The unit delivers a rated speed of 2500 RPM at 60/100 K surface cooling, with a maximum speed of 4000 RPM, and peak current of 117 A. Under natural convection at 100 K, power output is 8 kW with 24.4 Nm torque from a 167 V supply. Constant standstill torque is rated at 28.0 Nm. The motor integrates a holding brake providing 22 Nm torque, employs a plain shaft with seal, offers liquid cooling, and supports both radial and axial shaft forces. Additional features include a centering diameter of 130 mm, flange size of 192 mm, motor size 112, output connector on side A, and an IP65-rated, black-coated housing conforming to insulation class F. The device weighs 34 kg and uses winding code 035.

Frequently Asked Questions

In what environments is the MHD112B-035-PG1-AN housing particularly advantageous?

The liquid-cooled, sealed metal housing excels in high-temperature or contaminated environments. It efficiently dissipates heat while protecting internal components from external contaminants.

What’s the purpose of using a digital servo feedback encoder in this motor?

Digital feedback provides faster signal transmission and better noise immunity. This results in smoother motion control and precise synchronization in multi-axis systems.

How does the power connection orientation to side A affect installation design?

It determines cable routing and space clearance requirements within control cabinets or machinery. Proper layout planning minimizes stress on connectors and simplifies maintenance access.

What are the implications of using a plain shaft versus a keyed shaft?

A plain shaft requires a secure friction-fit coupling or clamping hub to transmit torque effectively. It allows for higher rotational balance and reduced vibration in dynamic applications.

How does motor size 112 influence torque density and system integration?

It provides a balance between compact form and high torque output suitable for medium-to-heavy-duty tasks. Integrators can pair it with robust drives without space constraints typical of larger motors.
