Product Description:
The MKD112B-048-GP1-BN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a rotary actuator, it supplies commanded motion and holding capability to automated machinery when paired with a suitable drive controller. In industrial automation, units from this series convert drive current into controlled mechanical torque so that positioning tables, packaging axes, or material-handling cells move with repeatable speed and accuracy. This operating principle allows the motor to support both dynamic motion and stable positioning in machines that require precise response during continuous production.
At zero rotor speed, the motor can exert a continuous torque of 28.0 Nm, allowing it to maintain load during static clamping or low-speed feed operations. Mounting is done through a 192 mm square flange, while the 130 mm centering pilot keeps the housing aligned with the driven equipment. The electromagnetic design uses winding code 048, which corresponds to the coil impedance and current rating expected by the companion drive. A spring-applied brake provides 22 Nm of holding torque when power is removed, and the housing includes a shaft seal to help limit the ingress of cutting fluid during operation. Power and feedback circuits exit through an output connector, which keeps electrical connections grouped at the motor body.
Electrical and feedback hardware are oriented toward the rear because the connections are on Side B of the stator housing. Rotational feedback is generated by a resolver feedback transducer, and the control system uses this signal for closed-loop regulation. The drive end uses a shaft with a keyway, so torque is transferred through keyed couplings rather than shrink fits. With a frame code of 112 and a motor length designation of B, the unit balances inertia and installation space for medium-power servo axes. This layout supports integration into machine assemblies where accurate alignment, stable feedback, and secure torque transmission are all required.
