Product Description:

The MKD112B-058-GG2-BN is a servo motor produced by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Built for automated machinery, the unit converts commanded drive current into controlled rotation so indexing tables, gantry axes, and packaging spindles can follow programmed motion profiles. Its electrical and mechanical interfaces support integration into closed-loop positioning systems that require stable torque output and dependable sealing against plant contaminants.

A continuous standstill torque of 28.0 Nm allows the motor to hold load under rated current without an external brake. The square flange pattern measures 192 mm, and a 130 mm centering diameter helps keep the motor aligned during installation. Class F insulation permits winding temperatures up to 155 °C during cyclic duty. The housing is sealed to IP65, which helps keep out dust and protects the motor against water jets in industrial environments. The motor uses winding code 058, which matches its electrical characteristics to compatible drive inverters.

Electrical connections exit on Side B through a molded output connector, keeping service space clear at the shaft end. The motor uses a plain shaft with an integral shaft seal, allowing direct coupling to clamped hubs while helping prevent lubricant migration. Motion feedback is provided by resolver feedback (RSF), and with the drive controller it supports a relative detection accuracy of ±8 angular minutes across the speed range. The permitted ambient air temperature is 0–40 °C, which suits typical enclosed machine spaces without forced cooling. Frame code 112 and length code B balance inertia and power density for medium-frame servo applications, and the relative position design relies on the drive for reference after power cycles rather than on a battery-backed multiturn encoder.
