The R911282234 (MHD112B-058-PP1-AN) is a Rexroth Indramat servo motor with IP65 protection, suitable for environments exposed to dust, water, and corrosive substances such as dilute acids, alkalis, hydraulic oil, and seawater. This servo motor integrates a digital feedback system with a multiturn absolute encoder for high-resolution (>4096 revolutions) position detection and real-time control. The unit features a keyed shaft with a shaft seal, a centering diameter of 130 mm, a flange size of 192 mm, and utilizes a liquid cooling system with additional options for natural convection or forced air via external blower. It delivers 28.0 Nm of continuous standstill torque and includes a holding brake rated at 22.0 Nm. Power connection is oriented to side A via an output connector. Designated winding code is 058, and motor length is specified as size B.

Frequently Asked Questions

How does the MHD112B-058-PP1-AN support secure mechanical coupling under load?

It features a keyed shaft that ensures stable torque transmission. This prevents slippage during high-cycle or reversing load applications.

Is position accuracy preserved during power loss or system restart?

Yes, it provides absolute position detection over 4096 revolutions. This allows immediate motion resumption without homing after shutdown.

What safety function is included to prevent shaft movement during idle or fault states?

The 22 Nm holding brake locks the shaft when power is removed. This ensures secure load retention in vertical or static applications.

Can this model maintain torque without rotation in precision holding tasks?

It delivers 28 Nm continuous torque at standstill. This supports stable performance in dwell-phase or press-hold applications.

How is heat managed in long-duration or high-load operation?

It uses a liquid-cooled housing to maintain thermal balance. This allows consistent torque output without thermal derating over time.
