Product Description:

The MKD090B-047-GP0-KS is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. In factory automation, the unit converts electrical energy from a drive controller into controlled rotary motion for indexing tables, packaging stations, and similar axes. This model is part of the 090 frame family, uses motor length code B, and relies on resolver feedback so the controller can close position, velocity, and torque loops with minimal delay. That feedback arrangement supports stable motion control during repeated starts, stops, and direction changes.

Mechanical mounting dimensions center on a 110 mm centering diameter and a 140 mm square flange, allowing the B-length housing to seat against standard machine frames without shims. At the shaft, the motor can supply 12.0 Nm of continuous torque while maintaining an IP65 enclosure rating, which helps protect internal components from dust and low-pressure water exposure. Motion feedback is delivered by resolver feedback (RSF), an analog sensing method that provides rotor position information to the drive. The motor connections are oriented on side B, and the stator insulation uses class F material with a thermal limit of 155 °C.

The shaft has a keyway and a shaft seal, allowing the motor to couple to gears or pulleys while helping keep contaminants away from the bearing area. The motor uses winding code 047, and electrical terminations are made inside the connection box, which helps maintain EMC shielding and keeps wiring organized. Position evaluation is relative, giving the drive a system accuracy of ±8 angular minutes when calibrated. The permitted ambient temperature range is 0–40 °C, and the unit is supplied without a holding brake, so the shaft can rotate freely when drive power is removed. This operating setup is suited to axes that rely on drive-controlled holding torque or an external mechanical restraint at standstill.
