Product Description:

The MKD041B-058-GP0-KS is a synchronous servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. The unit converts electrical drive commands into rotary motion for positioning tasks in automated machinery, conveyors, and handling modules. When used with a compatible digital drive, it supports repeatable torque and speed control for closed-loop industrial motion. Its compact frame makes it suitable for axes that need accurate movement without a large motor body.

It delivers a continuous standstill torque of 2.7 Nm, which provides stable holding force when motion is stopped. The square mounting interface has a flange dimension of 82 mm and a centering diameter of 50 mm, helping the frame align with common gearbox or machine flanges. Electrical and feedback terminations are routed on Side B through a sealed connection box, which helps keep cable routing organized. The shaft is keyed and includes a shaft seal to limit coolant entry during operation. The housing has an IP65 enclosure rating, and the insulation class is F, allowing winding temperatures up to 155 °C. The motor is supplied without a holding brake, so external holding force is needed if the load must remain fixed after power is removed.

Winding code 058 indicates the electrical winding used with standard MKD drive inverters, while motor length code B keeps the stack short for compact axes. Rotor position is measured by resolver feedback for relative position detection, and the stated accuracy of ±8 angular minutes suits many general-purpose servo loops. Motor size 041 gives the unit moderate inertia for small handling or pick-and-place applications. Operation is approved in ambient temperatures from 0–40 °C, which fits typical machine environments. A keyed shaft transfers torque directly to pulleys or couplings.
