Product Description:
The MKD090B-047-EP0-KN is a servo motor built by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Designed for closed-loop CNC and factory handling equipment, this motor couples a permanent-magnet rotor with digital drive controllers to deliver repeatable torque and speed commands. Its compact 090 frame and B-length housing place it between the lighter MKD065 units and the larger MKD112 models, making it a mid-range choice for indexing tables, pick-and-place arms, and automated conveyors.
The motor produces a continuous standstill torque of 12.0 Nm, allowing it to hold or slowly drive loads without exceeding thermal limits. A centering diameter of 110 mm aligns the stator face precisely with the mounting pilot, while the 140 mm square flange provides a standardized bolt pattern for attachment to gearboxes or mechanical frames. Power and feedback conductors exit on side B, so cables can be routed away from the driven equipment. All terminations are made through a sealed connection box, which provides a rigid strain-relief point instead of flying leads.
The housing carries an IP65 rating, so water jets and dust do not reach the stator laminations. Class F insulation tolerates winding temperatures up to 155 °C, and the permissible ambient range of 0–40 °C covers most indoor machine halls without derating. Drive torque is transmitted through a shaft with keyway, and a factory-installed shaft seal blocks lubricant migration from attached gear stages. Because the motor is supplied without a holding brake, external clamping or drive-based torque must secure vertical loads during power-off states. Winding code 047 corresponds to resistance and inductance values used by compatible drives, while the 090 frame size and B length help balance inertia against peak acceleration demands.
