Product Description:

The MHD115B-024-NG0-BA is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It delivers closed-loop motion for automated tooling, packaging, and handling axes where precise speed and position control are required. The motor uses a relative position detection scheme so the drive can track rotor angle during operation. Because it is supplied without a holding brake, stationary load retention must be provided by an external mechanical lock when needed.

At a standstill, the rotor can produce a continuous torque of 50.0 Nm, giving machines steady drive force for holding and low-speed feed motions. The square mounting flange measures 192 mm across, while the 180 mm centering diameter locates the housing concentrically on the machine faceplate and helps keep radial runout low. Motor length code B gives the unit a moderate stack height that balances inertia with power density. Cooling relies on natural convection, so the housing fins dissipate heat without forced airflow. Electrically, winding code 024 sets the phase resistance and inductance values expected by compatible Rexroth drive inverters.

Position and velocity data are generated by the digital servo feedback (HSF) encoder, which provides high-resolution signals for tight control loops. Mechanical output is provided by a plain shaft, allowing compression couplings to be used where low backlash is important. An integrated shaft seal blocks fluid and dust ingress at the bearing journal, supporting use in general industrial environments. Power conductors reach the stator windings through an output connector routed to side B of the terminal box, which helps maintain cable clearance toward the rear of the machine. The frame designation 115 places the motor in the corresponding size class within the MHD family.
