Product Description:

The MHD115B-059-NP1-RA servo motor is manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In industrial automation, this motor converts controlled electrical energy into rotary motion for axes that require accurate velocity and position loops. The naming code conveys its size, winding, and feedback style, helping users match it with compatible controllers and mechanical interfaces. By combining relative position sensing with an internal brake, the motor supports production lines that must stop in a controlled way and hold position when power is removed.

The motor’s continuous torque at standstill reaches 50.0 Nm, allowing it to hold heavy inertial loads without overheating while the shaft remains stationary. For emergency or scheduled stops, the integrated brake supplies a moment of 70.0 Nm, so vertical or suspended loads can remain locked when the drive is disabled. Mechanical mounting aligns on a centering pilot of 180 mm, and the squared IEC flange measures 192 mm, providing a standard footprint for gearboxes or direct-coupled machinery. Electrical performance is tied to winding code 059, which indicates the motor’s resistance and inductance values so the selected drive can deliver rated current without saturation or instability.

Feedback is supplied through digital servo feedback (HSF), enabling high-speed commutation, while position evaluation remains relative position evaluation. Heat leaves the lamination stack by natural convection, eliminating the need for external blowers and keeping enclosure complexity low. A keyed shaft transmits torque to pulleys or couplings, and a factory-installed shaft seal blocks dust and coolant ingress. The power connector is oriented to the right side of the housing, and its plug-in design simplifies cable routing and connection. Size 115 and length code B complete the dimensional profile for drive selection.
