Product Description:
The MKD025B-058-GG0-KN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It converts commanded current from a digital drive controller into controlled angular motion, making it suitable for pick-and-place axes, small positioning tables, and similar automation tasks that call for repeatable velocity and acceleration profiles. Used as the primary mover in compact machines, the motor integrates with standardized mounting flanges so it can be coupled directly to gearboxes or belt transmissions without intermediate adapters. Its compact format suits installations where short axis travel, quick response, and precise stop positions are important for the overall machine cycle.
The mechanical interface centers on a 40 mm locating diameter that aligns the motor with the machine frame, while the rectangular flange measures 54 mm across to match common drilling patterns. Motor leads exit on side B, which helps keep cable routing away from nearby moving parts. A sealed connection box houses both power and feedback terminations and helps protect them from oil mist and fine dust. During continuous stall duty, the motor delivers 0.9 Nm of torque, which is suitable for light loads and short-transfer mechanisms. The mounting layout also makes the motor easier to place in compact assemblies that have limited clearance around the drive end.
Rotor position is monitored by resolver feedback, supplying analog sine-cosine signals that the drive interprets as relative position data for homing routines and velocity loops. The motor belongs to frame size 025 and uses length code B, a compact stack that helps reduce inertia for fast acceleration. Winding code 058 matches the electrical characteristics expected by compatible Indramat power modules. A plain shaft transfers torque without key stress concentrations, and a fitted shaft seal helps prevent lubricant migration into the stator cavity. The unit is supplied without a holding brake, so external clamping is required when the load must remain fixed after power is removed.
