The R911297660 (MHD112B-048-PP2-AN) servo motor is specified for integration in servo systems with a nominal speed of 2800 RPM and a maximum speed of 4500 RPM at 160A input current. It features a brushless, four-pole pair construction and achieves a torque constant of 0.8 Nm, voltage constant of 80V per 1000 revolutions, and a winding resistance of 0.22 Ω at 20°C. The unit supports a continuous standstill torque of 28.0 Nm and includes a holding brake with 32.0 Nm torque. The liquid-cooled housing, keyed shaft with seal, and digital servo feedback with integrated absolute encoder (>4096 revolutions) are designed for robust performance. The motor weighs up to 34 kg, with a centering diameter of 130 mm, 192 mm flange, and connects on side A via output connector. Separate power and feedback cables are required for controller interface to minimize interference.

Frequently Asked Questions

How is absolute position maintained during frequent restarts in automated systems?

The integrated digital encoder supports absolute detection beyond 4096 revolutions. It eliminates the need for homing cycles, preserving position across shutdowns.

What safety feature ensures shaft locking in static or vertical load applications?

It includes a 32.0 Nm holding brake that secures the shaft when power is lost. This prevents drift or load drop in fail-safe conditions.

How is mechanical coupling stabilized under reversing load cycles?

The keyed shaft provides tight, backlash-resistant engagement. It ensures consistent torque transfer during bidirectional motion.

Can the MHD112B-048-PP2-AN sustain output torque in dwell-based positioning tasks?

It delivers 28.0 Nm continuous torque at standstill. This supports static load-holding without loss of torque over time.

How does the power connector orientation influence electrical integration in tight enclosures?

The side A output connector allows efficient cable routing in front-facing layouts. It simplifies wiring in machines with constrained access areas.
