Product Description:

The MHD115C-035-NG0-BA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Intended for precision motion control, the unit translates commanded current from a drive controller into accurate torque and speed for conveyors, gantries, and machining modules. Its size 115 housing and C-length stator provide the mechanical envelope for applications that require sustained power without enlarging the footprint, while the plain shaft interface simplifies integration with couplings or gear stages.

Its continuous stall capability reaches 70.0 Nm, supporting holding and machining without overheating. The motor has IP65 protection, which seals the stator, encoder, and output connector against dust ingress and water. Dimensional alignment is assisted by a centering diameter of 180 mm and a flange of 192 mm; these faces support accurate alignment with same-frame assemblies. Heat produced in the windings is dissipated by natural convection, a cooling method that eliminates fans. Class F insulation tolerates winding temperatures up to 155 °C. Power enters through an output connector on side B, helping keep the wiring harness clear of moving axes. A shaft seal blocks oil splash, and winding code 035 corresponds to torque constants used by matching Indramat drives.

High-resolution positioning is supported by a system accuracy of ± 0.5 angular minutes. This accuracy comes from the Digital servo feedback (HSF) encoder, which relays relative position data to the drive. The feedback system uses an optical measurement method, which maintains resolution without contact wear. The motor operates without a holding brake, so external hardware must secure vertical loads. Acceptable ambient temperatures span 0 to 40 °C during service and -20 to +80 °C during storage, with installation permissible up to 1000 m above mean sea level.
