Product Description:

The MHD115C-035-NP0-BN is a servo motor from Bosch Rexroth Indramat in the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical energy into controlled rotary motion for positioning and velocity tasks on production lines, packaging axes, and material-handling equipment. Its digital feedback interfaces with Rexroth drives, allowing the motor to deliver precise torque and speed under real-time automation commands. As part of the manufacturer’s high-torque range, it suits applications that demand continuous duty and accurate repeatability.

Its continuous standstill torque is rated at 70.0 Nm, providing steady holding force without thermal overload during static loading phases. Heat generated in the stator is extracted by liquid cooling, so coolant flow keeps winding temperature below the Class F limit and permits full current at low motor speeds. The housing has an IP65 protection rating, sealing the windings against airborne dust and low-pressure water jets on the plant floor. Rotor position is reported by digital servo feedback (HSF), which streams high-resolution incremental data to the drive. Mechanical integration uses a 192 mm flange, aligning with ISO dimensions for large-frame gearboxes and direct-drive mountings.

The mechanical interface provides a 180 mm centering diameter for precise spigot seating and a keyed shaft protected by a shaft seal. The power lead exits on side B through an output connector that simplifies cable routing. Position feedback is produced optically and evaluated as relative counts, yielding a system accuracy of ± 0.5 angular minutes for repeatable indexing. The motor operates in ambient temperatures from 0 to 40 °C and may be stored at -20 to +80 °C. Frame size 115, length C, winding code 035, and Class F insulation complete the electromagnetic design, while the omission of a holding brake reduces inertia.
