Product Description:
The MKD090B-046-GP1-KN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. In automated assembly lines and packaging cells, this motor converts commanded drive current into controlled rotary motion so axes can position loads accurately and repeatably. Its integration with Rexroth digital drives allows tight velocity and position loops, making it suitable for material handling stations, indexing tables, and similar applications that demand coordinated movement within tight machine spaces.
The motor has a centering diameter of 110 mm and a square mounting flange that measures 140 mm, giving a clear reference for coupling the housing to machine frames. At standstill it can deliver 12.0 Nm of continuous torque, and the factory-installed holding brake supplies 11 Nm to secure vertical or overhung loads when power is removed. The shaft has a keyway and a shaft seal to block lubricant migration into the stator chamber. With a sealing grade of IP65, the enclosure tolerates airborne dust and low-pressure water jets. Thermal endurance falls under insulation class F, and the motor uses winding code 046. Size code 090 and motor length B keep the stator stack compact, supporting installations where space around the drive train is limited.
Electrical terminations are routed on Side B of the housing through a cast connection box, simplifying cable bends inside the cabinet. Rotor angle is reported by resolver feedback (RSF), which supplies analog sine-cosine signals for drive interpolation, so the system uses relative position detection. The permitted ambient operating temperature range is 0 to 40 °C. Motion accuracy is maintained within ±8 angular minutes through the resolver resolution and the motor's mechanical tolerances.
