Product Description:
The MKD112C-058-KG3-AN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MKD Synchronous Motors series. This motor type converts electrical energy into controlled rotary motion for tasks such as positioning axes or driving conveyor sections in automated machinery. By combining an internal resolver, an integrated holding brake, and application-specific windings, the unit delivers the closed-loop performance required in industrial automation cells. Its mechanical frame matches the ISO flange pattern used in modular drive packages.
At the mechanical interface, the motor centers on a 130 mm pilot to align precisely with the driven load, while its square flange measures 192 mm on each side for direct mounting to standardized gearboxes. Electrical and feedback terminations are routed to side A, and a single output connector simplifies cabling inside the cabinet. Under continuous stall conditions, the rotor can deliver 38.0 Nm of torque without exceeding thermal limits, allowing the axis to maintain load forces during static clamping or low-speed creep moves. The winding code 058 pairs this torque constant with drive modules rated for the required current, and the designated motor length C accommodates the necessary active stack without enlarging the footprint.
For dynamic positioning, a resolver feedback package is integrated with the stator, providing rotor angle information to the drive electronics, and the system retains multi-turn position information with Absolute (>4096 revs) support. An internal holding brake rated at 70 Nm engages automatically when power is removed, securing vertical or overhung loads without external clamps. The motor employs a plain shaft with an installed shaft seal to block lubricant ingress, and its size 112 stator core supplies additional inertia for smooth velocity regulation. With the shaft seal in place, the unit is suited for installation in lightly contaminated environments where oil spray or dust could reach the coupling area.
