The Bosch Rexroth R911280588 (MKD112B-048-KP1-AN) is a synchronous servo motor featuring natural convection cooling and an IP65 protection class, suitable for demanding applications with frequent stop-start cycles. The motor incorporates a shaft with a sealing ring and a keyway in compliance with DIN 6885-1, and is equipped with a 22 Nm electrically releasing holding brake. Resolver feedback with integrated encoder enables absolute position detection for over 4096 revolutions. Key specifications include a 192 mm flange size, B motor length, 28.0 Nm continuous standstill torque, 2800 min⁻¹ rated speed, 102 Nm maximum theoretical torque, a moment of inertia of 192×10⁻⁴ kg·m², and a 40-minute thermal time constant. Power and signal connections are oriented to Side A.

Frequently Asked Questions

What ensures fail-safe shaft retention?

A 22 Nm spring-applied holding brake locks the axis during outages or e-stops, preventing gravity-driven drift and maintaining precise fixture relationships until power and motion resume.

What is the rated speed for steady duty?

The motor operates at 4,000 min⁻¹ continuous speed, balancing thermal limits with throughput to support sustained traverses with accurate registration and consistent feed rates.

What maximum speed supports rapid traverses?

It reaches 6,000 min⁻¹, enabling fast repositioning where motion profiles allow, minimizing non-cut time while keeping mechanical stress and drive current within safe limits.

How is concentric mounting ensured?

A 130 mm centering diameter precisely registers reducers or pulleys, minimizing runout and vibration, protecting bearings, and maintaining smooth motion during repetitive reversals.

How does the motor reduce airflow-related maintenance?

Natural convection cooling eliminates the need for an external fan, lowering failure risk and debris ingress while keeping predictable thermal performance during continuous operation.
