Product Description:

The MHD115B-035-NG0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Its size 115 geometry and length code B place it in a medium-frame format suited to handling stations, tool changers, and indexing tables that require controlled rotary motion. The motor uses a plain shaft for direct coupling to gearboxes or timing pulleys, and its housing is arranged for coolant circulation in machines that already use a liquid cooling circuit.

The motor can hold machinery at standstill with 50 Nm of continuous torque. The housing is sealed to IP65, helping keep dust and washdown spray away from internal components. Heat is removed by a liquid cooling jacket, and operation is permitted within an ambient range of 0 to 40 °C. Rotor position is monitored optically, and the feedback system supports an accuracy of ± 0.5 angular minutes for precise interpolation and coordinated multi-axis motion. This arrangement supports stable positioning behavior when the motor is paired with a compatible drive and proper feedback setup.

A centering pilot of 180 mm aligns the housing with the machine interface, and a flange diameter of 192 mm provides a robust mounting face. The windings use Class F insulation, which permits higher internal thermal stress without damaging the insulation system. Position data is delivered through digital servo feedback (HSF), so the drive references the motor during startup before closed-loop motion begins. The motor has a shaft seal but comes without a holding brake, making it better suited to axes that use external braking or clamping. Power leads exit on side B through an output connector, which helps with cable routing in compact machine layouts. Storage from -20 °C to 80 °C and installation up to 1000 m above mean sea level are permitted.
