Product Description:

The MKD090B-035-GG1-KN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. It converts electrical power into controlled rotary motion for CNC tables, packaging axes, and similar positioning tasks found in automated plants. Because the motor belongs to a closed-loop drive family, it works with controllers that read its resolver signals and modulate current so commanded speed and position remain stable when the mechanical load changes.

This unit can deliver a continuous standstill torque of 12.0 Nm, allowing it to hold static loads without thermal overload when the shaft is clamped by the drive. The square mounting interface follows a flange pattern of 140 mm, and the stator nose centers in machine housings with a 110 mm locating diameter for repeatable alignment. Electrical terminations are collected in a connection box on side B, keeping power and signal conductors on the side opposite a gearbox or coupler. Motion feedback is provided by resolver feedback, which supplies analog sine and cosine signals for rugged position and speed detection in harsh environments. This layout supports straightforward cable routing and stable rotor-angle tracking during reversing motion.

The built-in brake supplies 11 Nm of static torque so vertical axes remain secure whenever the inverter is disabled. Output power is transferred through a plain shaft, which eliminates keyway stress concentrations and supports clamp-style couplings. Windings identified by code 035 set the rated current and voltage pairing for compatible MKD drives. There is a shaft seal at the output journal, which helps prevent lubricant migration and limits contaminant entry near the bearing area. The medium B motor length provides more active material than a shorter housing of the same frame size, which supports repeated duty in automated handling and indexing applications.
