Product Description:

The MKD025B-058-KP1-KN is a servo motor manufactured by Bosch Rexroth Indramat in the MKD Synchronous Motors series. It is intended for compact industrial axes where controlled rotary motion is required to index tooling, advance conveyor stations, or align fixtures. When connected to a compatible drive controller, the motor’s feedback device, torque capability, and sealing help it maintain commanded speed or hold position under load. This makes it suitable for packaging, transfer, and light assembly equipment where repeatable motion is required.

The motor’s flange dimension is 54 mm, giving it a compact square face that matches the size-025 frame class and aligns with a 40 mm centering diameter for repeatable mounting. Power and feedback terminations are routed on side B, and the leads enter through a sealed connection box, which helps organize cable routing in tight machine spaces. At stall, the rotor delivers 0.9 Nm of continuous torque, which suits lightweight grippers or indexing wheels without overheating the 058 winding. The housing has an IP65 rating, so dust and low-pressure water jets will not affect the stator or the Class F insulation system.

The integrated holding brake clamps the shaft with 1 Nm of static torque, which helps prevent drift on vertical axes when the drive is disabled, and the shaft seal separates lubricant from outside contaminants at the output end. Motion feedback is supplied by resolver feedback with an integrated encoder, supporting absolute evaluation over more than 4096 revolutions, and the control loop can rely on system repeatability within ±8 angular minutes. A keyed steel shaft transmits the commanded torque, and the permissible ambient temperature range of 0–40 °C supports operation in standard cabinet-mounted machinery. The B-length stack keeps these operating characteristics in a compact motor body without increasing the overall footprint.
