Product Description:
The MKD090B-035-KP2-KN is a permanent-magnet AC servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within an automation cell, it converts regulated drive current into repeatable rotary motion so that indexing tables, ball-screw actuators, and compact conveyor sections can track commanded profiles without manual calibration. Its mechanical interface follows standardized dimensions, so it fits common brackets and couplings used on automation axes. Because torque is generated synchronously with the stator field, speed remains directly proportional to drive frequency, which simplifies diagnostic trending in multi-axis systems.
The motor develops a continuous standstill torque of 12.0 Nm, giving it the capacity to hold loads against gravity or friction without forced cooling. A square mounting flange that measures 140 mm on each side mates with ISO adapters, and the 110 mm centering pilot locates the housing concentrically so the bearings are not side-loaded. Output power passes through a shaft with a keyway, allowing pulleys or rigid couplings to transmit cyclic forces without slip. Electrical characteristics follow winding code 035, which indicates the stator wire gauge and its nominal voltage and current pairing with compatible drive controllers. The B-length lamination stack provides additional copper for thermal headroom while keeping the overall depth short enough for back-to-back mounting on dual-shaft gearboxes.
Cables enter on side B through a cast-aluminum connection box, so power and feedback leads can be disconnected without disturbing the opposite face of the machine. Rotor position is measured by resolver feedback, and the signal is processed as absolute position over more than 4096 revolutions, eliminating the need for homing after power loss. Size code 090 indicates the stator diameter, and the shaft seal limits lubricant migration when the motor is coupled to gear reducers or mounted in an oil-mist environment.
