Product Description:

The MKD090B-058-GP0-KS servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. It acts as a rotary actuator for closed-loop automation axes, where its electrical characteristics pair with digital controllers to position loads accurately and repeatably. In service, the unit converts drive current into regulated mechanical rotation for machine tools, packaging equipment, and material-handling stations. Its synchronous design supports stable speed control and repeatable motion during indexing, feed, and transfer tasks.

The mounting dimensions show how the motor fits onto the machine frame. The motor uses a flange that measures 140 mm across and a centering diameter of 110 mm to align the housing with the driven assembly. Power and feedback conductors exit on side B through a sealed connection box, which helps protect the terminations and keeps cable routing compact. At standstill, the motor can exert 12.0 Nm of continuous torque, and rotor position is monitored by resolver feedback. A class F insulation system supports the winding, and the B motor length balances inertia with overall package depth.

The housing is sealed to IP65 to resist dust and low-pressure water jets, and an integral shaft seal helps protect the output end. The output uses a keyed shaft, and the motor has no holding brake, so the load must be secured by external means when power is removed. Motion accuracy is characterized by a system precision of ±8 angular minutes, with relative position detection referenced by the resolver. Operation is permitted from 0–40 °C, and winding code 058 indicates the electrical values used with compatible MKD drives. This arrangement suits applications that need dependable positioning without an integrated brake.
