Product Description:

Bosch Rexroth Indramat's MHD115B-058-NP1-BA belongs to the MHD Synchronous Motors series and is supplied as a servo motor for precise rotary motion in automated machinery. As a synchronous servo motor, it converts controlled electrical input into regulated torque and speed for positioning, feeding, and indexing duties. The keyed shaft supports positive torque transmission to connected machine elements, while optically scanned relative position detection allows the drive to reference position after homing and maintain alignment during repeated moves. Power and feedback cables exit on side B through an output connector, which helps route wiring away from the motor body. The unit may be stored between -20 °C and +80 °C and installed up to 1000 m above mean sea level without derating.

At standstill, the rotor can deliver a continuous torque of 50.0 Nm, letting heavy loads be held without extra gearing. The centering shoulder measures 180 mm and mates with a 192 mm square flange for a rigid mechanical interface, which helps keep the shaft aligned with coupled machine elements. Environmental sealing is rated IP65, and a positive-pressure labyrinth together with a shaft seal helps block dust and low-pressure water jets from reaching internal parts. A built-in holding brake supplies 70.0 Nm of static torque for vertical axes or loads that must remain in place when power is removed. Heat is removed through natural convection at the housing, so operation does not require forced ventilation.

For position control, the motor uses Digital servo feedback (HSF), which combines high-resolution incremental tracks with electronic nameplate data for closed-loop regulation. The feedback system achieves repeatability within ± 0.5 angular minutes, supporting demanding interpolated motion and stable contouring behavior. Safe operation is specified from 0 to 40 °C ambient, and the winding code 058 uses insulation class F windings for elevated temperature tolerance. The drive references the encoder's relative position signal after homing, making the motor suitable for pick-and-place gantries, packaging stations, and other automation tasks that require accurate torque delivery.
