Product Description:
The MKD090B-085-KP1-AN servo motor is built by Bosch Rexroth Indramat for the MKD Synchronous Motors series and is intended for closed-loop motion axes in automated machinery. As a permanent-magnet AC unit, it converts drive current into controlled shaft rotation, following position and speed commands in pick-and-place heads, gantry tables, and packaging spindles. This configuration supports repeatable motion in applications that depend on stable response during frequent starts, stops, and direction changes.
This model can maintain a continuous standstill torque of 12.0 Nm, giving the drive margin to hold static loads without overheating. A flange size of 140 mm fits common mounting patterns for this motor class. Position feedback comes from integrated resolver feedback, allowing sinusoidal commutation with good immunity to electrical noise. The housing carries an IP65 rating, which helps prevent dust ingress and resists water jets when the shaft seal is installed. Commanded angles are maintained within ±8 angular minutes, supporting accurate interpolation in coordinated multi-axis motion. Power and encoder cabling exit on side A, and the motor uses frame size 090 with length code B.
A holding brake rated at 11 Nm secures the load during power-off events, while the centering diameter of 110 mm aligns the housing accurately to the machine register. Operation is permitted from 0–40 °C, enabling use in typical factory environments when adequate airflow is available around the motor. Class F insulation supports winding temperatures up to 155 °C during normal thermal loading. Absolute position detection beyond 4,096 revolutions eliminates homing moves after startup. The keyed shaft and shaft seal help transmit torque securely while limiting the entry of contaminants.
