Product Description:

The MKD112B-058-KP1-BN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It supplies precisely regulated rotary motion for machine axes, conveyors, and handling modules that require closed-loop speed and position control in industrial automation. Its synchronous design supports smooth torque delivery, controlled acceleration, and accurate stopping during repetitive motion tasks.

This model delivers a continuous standstill torque of 28.0 Nm, allowing the shaft to hold substantial load without overheating when stationary. A centering diameter of 130 mm aligns the housing accurately to the machine frame, and the flange size of 192 mm sets the bolt pattern for common mounting surfaces. Power and feedback cabling exit on Side B, which can simplify routing where clearance beside the driven equipment is limited and help keep cable runs clear of adjacent machine parts. The motor uses winding code 058, so its electrical characteristics suit compatible drive controllers and support predictable current control across the operating range.

A holding brake supplies 22 Nm of mechanical locking torque, helping keep vertical or indexing axes secure when power is removed. The enclosure has an IP65 rating to resist dust ingress and water jets, and the motor can operate continuously in ambient temperatures from 0–40 °C without external cooling in most production areas. Resolver feedback with an integrated encoder provides absolute position detection over more than 4096 shaft revolutions and supports system precision of ±8 angular minutes for consistent repeatability during rapid cycle sequences. The feedback arrangement allows the control system to monitor shaft position through extended travel, while the keyed shaft provides positive torque transfer to the driven load. A factory-installed shaft seal helps limit lubricant escape and contaminant entry at the drive end.
