The Bosch Rexroth MHD115B-024-NG1-AA (MPN: R911286090) is a servo motor designed for use with Indramat controllers, featuring digital servo feedback (HSF) for relative position detection. It is constructed with a fully enclosed IP65 housing, providing resistance to shock, dust, and water spray. The unit is equipped with a temperature sensor, plain shaft with seal, and an integrated holding brake delivering 70.0 Nm torque to secure the shaft when de-energized. Continuous standstill torque is 50.0 Nm. Cooling is achieved via natural convection. Key dimensions include a 192 mm flange, 180 mm centering diameter, and a motor length size B. The power connection is oriented to side A using an output connector. The motor employs a brushless, lifetime grease-lubricated design and is coated with a prime black finish for environmental protection. Winding code is 024.

Frequently Asked Questions

How does the holding brake enhance machine safety during power loss?

The brake instantly locks the rotor to prevent unwanted motion or load drop. The feature ensures immediate standstill protection in emergency stops.

What advantages come from the 50 Nm continuous torque at standstill?

The torque output allows the motor to sustain heavy static loads without overheating. The constant force delivery maintains precision under prolonged holding conditions.

How does the winding code 024 influence torque smoothness?

The winding configuration minimizes torque ripple during low speed operation. The current distribution enhances response uniformity across dynamic load shifts.

What practical benefits does the flange and centering diameter combination provide?

The standardized dimensions simplify mechanical alignment with gearboxes or couplings. The uniform fit reduces installation time and misalignment risk.

How does the side A power connection orientation aid machine design?

The lateral cable exit enables tight-space integration in control cabinets. The streamlined routing improves accessibility for maintenance and wiring.
