Product Description:
The MKD090B-085-GG0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a rotary actuator in industrial automation, it converts drive current into controlled mechanical motion for positioning and speed tasks in packaging lines, material-handling axes, and other CNC assemblies. It is suited to axes that require repeatable acceleration, deceleration, and controlled holding under drive regulation. The motor uses a plain shaft for direct coupling to suitable drive components, and it comes without a holding brake when passive locking is not required.
This model uses a centering diameter of 110 mm and a flange size of 140 mm, so it fits standard IEC motor mounts. This mounting format supports installation on common machine faces without special adapter plates. Power and feedback cables exit on Side B, a layout that keeps connectors clear of moving machine parts and simplifies cable routing around the axis. At standstill, the motor can deliver 12.0 Nm continuously, giving suitable holding torque for mid-range loads. Rotor position is reported through Resolver feedback (RSF), and this analog sensor supplies rotor angle data during rapid reversals for stable closed-loop operation.
Electrical insulation is rated to class F, allowing winding temperatures up to 155 °C during cyclic duty. The housing meets IP65, keeping dust and low-pressure water jets out of the stator chamber, while an integral shaft seal helps prevent lubricant migration. Closed-loop precision is held within ±8 angular minutes, so repeatable positioning can be achieved without an additional encoder on many applications. Continuous operation is intended for ambient temperatures of 0–40 °C, and operation outside that range requires derating or external cooling. The motor uses length code B and size code 090 for its overall stack and frame geometry, placing it in a mid-size configuration within the series.
