MKD090B-058-KG2-KN

The MKD090B-058-KG2-KN servomotor from Bosch Rexroth Indramat, part of the MKD Synchronous Motors series, represents a high-performance Servo Motor engineered for demanding industrial environments. This Synchronous Motor delivers a Rated Power of 3.7 kW at a rated speed of 3000 rpm, combining compact design with robust output. Featuring an IP65 protection rating and a Cooling Mode of Natural Convection, the unit ensures reliable operation under dust and water exposure while eliminating the need for auxiliary cooling systems. With a peak torque of 19.3 Nm and a continuous torque at standstill of 12.0 Nm, this servomotor is optimized for both dynamic motion control and static holding tasks. Its Resolver feedback w/ integrated encoder and Absolute (>4096 revs) position detection provide precise, multiturn position information for advanced automation applications.

Technical capabilities of the MKD090B-058-KG2-KN include a Motor Constant of 1.38 Nm/A and a Winding Resistance of 0.457 ohms, ensuring high torque per ampere and efficient current utilization. The built-in Resolver feedback w/ integrated encoder offers robust feedback in electrically noisy environments, while the Winding Code 058 and optimized winding pattern support rapid current transitions and low inductance. A Centering diameter of 110 mm and Connection Type via a Connection box facilitate standardized installation and straightforward cabling. The servomotor’s Shaft Seal design (Yes) and Plain shaft configuration provide reliable mechanical coupling and protection against contaminants.

Operational features and benefits emphasize maintenance-free performance and long service life. The Natural Convection cooling method eliminates fans or liquid circuits, reducing downtime and lifecycle costs. An Equipped Holding Brake secures loads during power interruptions or emergency stops, enhancing safety. The brushless architecture of the Motor Type minimizes wear, delivering consistent torque output and low acoustic noise at high speeds. With an Absolute (>4096 revs) position hold capability, the unit retains precise shaft orientation even after power loss, streamlining restart procedures.

Integration of the MKD090B-058-KG2-KN is seamless across diverse automation sectors. Its IP65 protection and compact footprint suit applications in printing presses, textile weaving machines, paper processing equipment, and conveyor transport systems. The standardized Centering diameter 110 mm and flange mounting options enable rapid retrofits and system upgrades. Designed for compatibility with Rexroth Indramat drives and controllers, this servomotor delivers plug-and-play integration for machine builders seeking high accuracy, reliability, and performance in industrial motion control solutions.
