Product Description:

The MKD041B-058-GG1-KN belongs to the MKD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor intended for precise position and velocity control of smaller axes in automated machinery, where consistent torque and accurate feedback are required for coordinated motion. In automated equipment, it works with a compatible drive to deliver repeatable starts, stops, and speed changes during synchronized motion. The motor uses the B housing length and Motor Size 041, giving it a compact form for pick-and-place units, gantries, and other smaller machine axes where quick response is important.

This model mounts to an 82 mm flange, and the concentric fit is ensured by a centering diameter of 50 mm. Power and feedback leads exit on side B through a sealed connection box that helps protect terminations from dust or oil. At standstill, the rotor can apply a continuous torque of 2.7 Nm, which supports stable holding force during low-speed interpolation and controlled positioning. The flange couples directly to gearheads or machine frames in packaging, handling, or light machining stations without additional adapter plates. The stator uses winding code 058, which suits medium-speed operation while keeping phase current compatible with compact drive controllers.

A maintenance-free holding brake supplies 2.2 Nm of static torque to secure vertical loads when power is removed, and its actuation circuit is routed through the main wiring enclosure. Rotor position is measured with resolver feedback, providing analog sine-cosine signals that the drive converts into high-resolution counts for closed-loop control. The motor employs a plain shaft with a factory-installed shaft seal, which helps prevent lubricant migration along the journal. Relative position is established after each homing cycle, and the compact frame keeps weight low for gantry or pick-and-place axes while maintaining responsive motion.
