Product Description:
The MKD025B-058-GG1-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Intended for compact axes in assembly stations, pick-and-place gantries, and light conveyor drives, the unit converts controlled electrical power from a drive into precise rotary motion for closed-loop automation. Its mechanical layout matches other MKD models, allowing direct mounting to gear stages or couplings while supporting accurate position regulation in compact machine spaces.
This model uses a 54 mm square mounting flange with a centering spigot of 40 mm, allowing alignment to companion gearheads without adapter rings. Continuous standstill torque is 0.9 Nm, which indicates the torque the motor can maintain at zero speed under continuous thermal conditions. Feedback comes from a resolver feedback (RSF) unit, so the drive receives analog sine-cosine signals for relative position calculation. Power and signal leads exit on the rear because the connectors are located on Side B inside a sealed connection box. The motor is size 025 with length code B, which places it in a compact frame suited to light-duty motion tasks where installation space is limited.
An integral holding brake is fitted, supplying 1 Nm of static torque to lock the rotor during power off and maintain axis position in vertical or overhung loads. The rotor extension uses a plain shaft configuration, so torque transmission depends on friction couplings or compression hubs instead of keys. A dedicated shaft seal sits behind the bearing shoulder to limit dust or coolant ingress when the motor is installed in IP54 machines. Winding code 058 identifies the motor winding used for this version. The sealed connection box and compact frame help the motor fit tightly arranged machine layouts where clean cable routing and protected electrical connections are important.
