Product Description:

The MHD115B-058-NG0-LN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within automated production cells, it forms the mechanical element of a closed-loop drive, turning electrical energy from the controller into precisely regulated rotary motion for positioning tables, gantries, or transfer mechanisms. The motor body follows the series dimensional code 115 with the B-length frame, giving machine designers a repeatable footprint when several axes must share a common mounting pattern and coolant circuit.

The rotor can deliver a continuous stall torque of 50.0 Nm, so static loads such as pressing heads or vertical axes remain motionless without overheating. A centering diameter of 180 mm aligns the stator concentrically inside heavy cast brackets, while the square flange size of 192 mm provides the bolt circle that locks the housing against torsion. Heat generated in the copper windings is extracted through liquid cooling; this keeps the stator temperature stable during prolonged high-current duty cycles and allows the full torque rating to be used in dense multi-axis enclosures. Rotor position is monitored by an integrated encoder that employs digital servo feedback (HSF), delivering incremental signals required for tight velocity loops and coordinated motion profiles with neighboring drives.

Cabling requirements are simplified because the power connector points to the left, matching common cabinet layouts where motor leads enter from the machine rear. Mechanical coupling is straightforward thanks to a plain shaft that accepts shrink discs or clamping hubs without the additional mass of a brake. A shaft seal is fitted to reduce coolant or lubricant ingress along the output journal, helping the bearing grease retain its viscosity. Electrical characteristics follow winding code 058, so drive tuning tables can be loaded automatically when the motor is identified by the controller.
