Product Description:
The MKD090B-035-KG0-KN is a servo motor manufactured by Bosch Rexroth Indramat and included in the MKD Synchronous Motors series. As a permanently excited AC unit, it converts drive current into precise rotary motion for indexing tables, handling modules, and other automation axes that rely on closed-loop speed and position control. The motor functions as an electromechanical actuator and can be paired with digital drive controllers to deliver constant torque, rapid acceleration, and repeatable positioning throughout demanding production cycles. It is well suited for applications that require frequent starts, stops, and direction changes during normal machine operation. The permanent-magnet design also supports responsive torque changes when the axis must settle quickly after short moves.
Its mechanical interface centers on a pilot diameter of 110 mm, providing accurate radial alignment against mounting surfaces, while the rectangular mounting pattern uses a flange size of 140 mm. The motor sustains a continuous standstill torque of 12.0 Nm, allowing static load holding without overheating when the shaft is locked. A plain shaft transmits torque directly, and a shaft seal helps prevent lubricant loss and particle entry at the output end. Length code B extends the active stack within the size 090 frame to increase usable power, and winding code 035 sets the electrical values expected by compatible controllers. Rotor position is reported by integrated resolver feedback, enabling sinusoidal commutation and stable low-speed operation.
For electrical terminations, power and feedback conductors exit on Side B, and a sealed connection box routes them to field cabling without exposing internal windings. The motor is delivered without a holding brake, so static safety locking must be provided externally when power is removed. Integrated electronics retain absolute position data over >4096 revs, which reduces the need for reference moves after startup. This arrangement keeps the cable outlet protected and supports orderly routing in machine layouts where the motor is installed close to guards, gearboxes, or structural members.
