Product Description:

The MKD041B-058-GP0-KN is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKD Synchronous Motors series. It serves as an electromechanical actuator that delivers repeatable rotation for axes that require tightly regulated speed or position in automated assembly cells, pick-and-place stations, and light-duty machining centers. When paired with a compatible drive, it supports accurate motion during repeated start, stop, and positioning cycles. The unit is supplied without a holding brake, so static load retention must be provided by the drive or external clamps when power is removed.

This model supplies a continuous standstill torque of 2.7 Nm, giving it the ability to hold loads steadily when motion is paused. An 82 mm square mounting flange aligns with common planetary gearheads and reduces adapter hardware, while a 50 mm pilot diameter helps center the motor accurately on the machine frame. Winding code 058 matches the motor to drives that deliver the correct current and back-EMF profile. Size designation 041 and length class B keep overall mass low while still providing the needed magnetic volume, and a shaft seal helps block lubricants or dust from entering the stator cavity.

Rotor position is monitored through resolver feedback (RSF), and the analog sine and cosine signals are converted by the controller into digital counts for relative position detection during homing routines. Power and feedback leads exit on side B, and the terminations are made inside a sealed connection box that supports organized wiring and helps protect the electrical interface. Mechanical coupling uses a shaft with keyway, allowing positive torque transmission without slip. This layout keeps the feedback path, cable exit, and shaft connection straightforward for integration into compact motion axes.
