The MPN R911276803 (MHD090B-035-PG0-UN) is a Bosch Rexroth servo motor featuring a liquid-cooled housing and grease-lubricated bearings designed for durability throughout the motor's operational life. It uses electronic commutation and a brushless design, reducing maintenance requirements. The motor integrates a digital servo feedback system with an absolute encoder capable of position detection over more than 4096 revolutions. Key specifications include a continuous torque at standstill of 12.0 Nm, plain shaft with seal, flange size of 140 mm, centering diameter of 110 mm, and motor length type B. Power and feedback connectors are turnable within a 270° range. The motor is suitable for applications requiring precise motion control and is compliant with DIN 42948 for flexible mounting.

What advantage does absolute position detection over 4096 revolutions offer?

It allows precise multi-turn tracking without external sensors, crucial for tasks needing consistent position memory. This is especially beneficial after power loss or in complex motion sequences.

Does the MHD090B-035-PG0-UN require a holding brake for vertical applications?

No, this variant comes without a holding brake, so external braking or control logic must be implemented for vertical loads. This affects safety and back-drive resistance in such setups.

Can the rotatable power connectors simplify cabinet wiring?

Yes, the 270° rotatable design allows flexible cable routing, reducing strain and improving layout efficiency. It's particularly useful in compact or multi-axis systems.

How does the plain shaft design influence coupling selection?

Plain shafts require external couplings or clamps suited to torque and misalignment tolerances. Misapplication may cause vibration or slippage under load.

Is the MHD090B-035-PG0-UN suitable for packaging line servo axes?

Yes, its continuous torque and precise feedback enable synchronized, high-speed motion ideal for indexing and sealing applications. Liquid cooling also minimizes thermal expansion during fast cycles.
