Product Description:
The MKD090B-085-KG0-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It acts as an electromechanical actuator that converts drive current into controlled rotary motion for positioning tasks on automated production equipment, assembly stations, and packaging lines. Its design supports feedback-based control loops so the axis can follow exact speed and position commands issued by the associated drive controller.
The motor supplies 12.0 Nm of continuous torque at standstill, allowing an axis to resist external loads without stalling while the drive delivers rated current. A 140 mm square flange provides the primary mounting surface, and the 110 mm centering diameter aligns the housing concentrically to the machine frame to minimize radial runout. Electrical power and feedback are routed through an output connector positioned on side B, a layout that keeps cabling clear of moving parts along that face. Rotor angle is reported through resolver feedback, allowing the control card to monitor position during operation. The housing has an IP65 rating, so the stator windings and bearings remain sealed against dust ingress and low-pressure water jets during washdown cycles.
For additional accuracy, the servo achieves ±8 angular minutes of system precision when paired with the specified drive. The shaft is a plain shaft, so torque is transmitted through clamp or interference couplings rather than keyed hubs, and a shaft seal helps protect internal grease from coolant splash. Operation is permitted at ambient temperatures from 0–40 °C, allowing installation inside typical electrical cabinets without supplemental heating. Thermal endurance is supported by Class F insulation, and motor length code B balances torque density against the envelope size of the 090 frame. Absolute position detection beyond 4096 revolutions eliminates the need for homing routines, while the absence of a holding brake reduces overall mass for dynamic axes.
