Product Description:

The Bosch Rexroth Indramat MKD041B-144-KG0-KN belongs to the MKD Synchronous Motors series and serves as an AC servo motor for automated production lines. It converts commanded current from a compatible drive controller into controlled rotary motion, which supports synchronized positioning in pick-and-place units, indexing tables, and feed systems. The motor is supplied as a finished unit with aligned feedback components, so it can be installed without extra mechanical adjustment of the sensing system. This arrangement helps the drive maintain stable speed and position control during repeated machine cycles.

Its centering boss measures 50 mm, providing an accurate locating surface between the motor housing and the machine interface. Power and signal leads exit on Side B, which helps keep cable routing away from the drive shaft and attached coupling. Position data is provided by resolver feedback with an integrated encoder, giving the drive both rotor angle information and finer feedback for closed-loop speed and position control. The motor uses a plain shaft, which suits clamp-style hubs and avoids the stress concentration associated with a keyed shaft. It is supplied without a holding brake, so any load that must remain fixed at standstill requires drive torque or an external locking device.

The electromagnetic winding uses code 144, which corresponds to the electrical characteristics expected by compatible MKD drives in continuous operation. The motor has size designation 041 and motor length code B, giving it a compact envelope suited to smaller multi-axis assemblies while keeping inertia moderate for quick direction changes. The motor includes a shaft seal to limit the entry of fine dust and light oil mist around the shaft opening. This layout supports use in enclosed machinery where clean cable routing, consistent feedback, and controlled shaft sealing are important. The compact housing leaves more room for couplings, guards, and adjacent axis hardware in densely packed equipment.
