Product Description:
The MKD090B-085-KP1-BN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop positioning and speed control in automated machinery. The integrated motor-encoder system sends precise rotor data to the drive controller so coordinated axes can remain synchronized during rapid motion changes. Because the drive continuously compares commanded motion with actual rotor position, the motor supports stable regulation during indexing, positioning, and variable-speed operation across repeated machine cycles.
The motor has a 140 mm square mounting flange and a 110 mm centering diameter, which help align the housing accurately on the machine frame. Its continuous standstill torque of 12.0 Nm allows the axis to hold load during pauses without thermal overload under normal operating conditions. All electrical terminations exit on Side B through a sealed output connector, which can simplify cable routing when adjacent components limit access. The motor has an IP65 protection rating to block dust and water spray, and the keyway shaft includes a shaft seal that helps keep lubricant inside the bearing area while reducing contaminant entry.
An integral holding brake supplies 11 Nm of static torque to lock the axis when power is removed, which is useful on vertical or suspended loads. The motor is intended for operation between 0-40 °C, helping protect the class F insulation system from excessive thermal stress during normal use. Absolute position feedback over more than 4096 revolutions is provided by resolver feedback, allowing startup without a homing move, and the system supports precision of ±8 angular minutes for fine interpolation tasks in packaging, printing, and assembly equipment. Motor size 090 with length code B gives a balance of inertia and performance for responsive acceleration and controlled speed changes.
