Product Description:
The MKD090B-085-GG1-BN belongs to the MKD Synchronous Motors series from Bosch Rexroth Indramat. Classified as a servo motor, it converts commanded drive currents into controlled mechanical motion for positioning tasks in automated machinery. A plain output shaft, a 110 mm centering diameter, and a flange sized for mid-frame gearboxes allow direct mounting to precision equipment, while the output connector keeps electrical integration straightforward. In automated systems, it is commonly used where the drive must regulate speed, torque, and position with repeatable behavior over frequent cycles.
This model supplies a continuous standstill torque of 12.0 Nm, which is the continuous torque it can hold at zero speed. The flange measures 140 mm, matching drive adapters that use standardized bolt circles. An enclosure rating of IP65 helps protect internal components from dust and direct water jets during washdown cleaning. System feedback accuracy is ±8 angular minutes, supporting controlled positioning on closed-loop axes. All power and sensor leads exit on side B, which keeps cable routing on one machine face. The plain shaft includes a shaft seal for use with coupled reducers.
An integrated holding device rated at 11 Nm secures the axis when drive power is removed. Rotor position is reported through Resolver feedback (RSF), which provides noise-tolerant analog signals that match many legacy Indramat drives. The windings use class F insulation, allowing winding temperatures up to 155 °C during intermittent peaks. The permitted ambient temperature range is 0–40 °C, which suits most factory-floor installations without special cooling hardware. Because the position signal is relative, the axis needs a homing routine after power-up, and the size 090 with length code B keeps the housing compact for moving assemblies.
