Product Description:

The MHD115C-035-PG1-AA is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended for industrial automation that requires accurate speed regulation and rapid positioning. The motor operates under closed-loop control with an integrated digital feedback encoder, allowing it to maintain commanded motion profiles in assembly cells, gantry axes, and processing equipment. That feedback channel lets the drive monitor rotor position continuously during acceleration, deceleration, and dwell periods.

The mechanical interface uses a centering diameter of 180 mm, providing a stable pilot fit between the housing and the machine frame. The square mounting flange measures 192 mm, giving a clear bolt pattern for installation with similar-sized machines. This combination supports repeatable alignment between the motor and coupled mechanical parts. Under standstill conditions, the electromagnetic system can deliver 70.0 Nm of continuous torque, which helps drive heavy loads without thermal overload when the shaft is held by the controller. Heat leaves the aluminum frame through natural convection, so no external blower or liquid jacket is required. Electrical power reaches the stator windings through an output connector, which maintains a sealed connection against coolant and dust ingress.

Rotor length code C pairs the active lamination stack with a frame size of 115, balancing inertia and power density for mid-range dynamic tasks. The three-phase leads exit the housing on side A, so cable routing can follow the machine backbone more easily. Absolute position detection over >4096 revolutions allows motion to resume without a homing cycle after power loss. The motor has a plain shaft without a keyway, which is suited to couplings that rely on frictional clamping instead of a keyed connection. An electromagnetic holding brake keeps loads stationary during shutdown. The motor uses winding code 035, which matches it with compatible drive inverters for correct current limits and commutation data.
