Product Description:
The MKD112B-048-GG1-AN is a rotary drive component manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It is intended for precision positioning and velocity control in automated equipment such as packaging lines, material-handling gantries, and metal-cutting centers, where closed-loop electrical actuation replaces pneumatic or hydraulic motion. In this role, the motor converts commanded current into controlled rotary motion for axes that require repeatable acceleration, stable speed regulation, and accurate response to changing load conditions.
This unit mounts to machinery through a flange that measures 192 mm across, while a centering diameter of 130 mm keeps the stator concentric with adjoining frames. The continuous torque available at standstill is 28.0 Nm, providing the steady rotary force needed for low-speed feed axes and holding against process loads between motion steps. A plain shaft allows coupling with backlash-free clamping hubs, and a shaft seal helps limit lubricant escape and particulate ingress. Electrical and feedback leads exit on Side A, and the output connector supports direct cable attachment with a clean routing path at the motor end. The housing also uses motor length code B, giving the unit a medium overall length within this frame class.
Rotor position is measured by a resolver feedback element, and the drive controller interprets this signal as relative position data for interpolation during commutation and speed control. Motion can be held when power is removed because an integrated brake supplies 22 Nm of static holding torque, which is useful on vertical axes or applications that must resist drift at standstill. Thermal and electrical behavior correspond to winding code 048, which matches the coil arrangement used for the motor's rated electrical characteristics. The frame size index of 112 places the motor in the matching mechanical envelope for this series and supports use in medium-power servo applications.
