Product Description:

The MKD090B-035-GP1-KN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It converts controlled electrical power from a drive into mechanical rotation for positioning, feed, or spindle axes in automated machinery. Designed for closed-loop operation, the unit includes resolver feedback and an integral holding brake to secure loads when power is removed. These features let the motor serve multi-axis manufacturing lines, packaging cells, and material transfer stations that require repeatable motion.

At standstill, the motor can deliver a continuous torque of 12.0 Nm, which is the sustained load it can support without overheating while locked in position. A centering diameter of 110 mm aligns the housing precisely on the machine frame and keeps radial runout low. Electrical terminations are routed through a connection box, simplifying shield connection and strain relief compared with plug connectors. Rotor position is monitored by resolver feedback (RSF), which supplies angle data over one turn for stable commutation even during signal disturbances. The mounting interface uses a square flange that measures 140 mm, allowing the motor to fit machine layouts that use the same footprint.

Power and feedback conductors exit on side B at the rear of the housing, which helps keep the cables clear of adjacent axes in compact enclosures. For static load holding, an integrated brake supplies 11 Nm of locking torque and engages automatically when the drive is disabled. The mechanical output is transmitted through a shaft with a keyway, enabling positive torque transfer into standard keyed couplings, while a shaft seal helps prevent lubricant ingress along the journal. Thermal behavior and electrical resistance come from winding designation 035, which matches the stator coils to drives delivering the appropriate current class and voltage to protect insulation life under continuous industrial duty.
