Product Description:

The MKD041B-144-KG0-KS is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKD Synchronous Motors series. It converts drive current from a compatible power module into precisely regulated rotary motion for positioning tables, pick-and-place heads, and packaging spindles in automated production cells. The compact housing and sealed bearing design let the motor operate as a durable electromechanical actuator for multi-axis machinery where accurate speed and position control are required. In closed-loop service, it supports repeatable motion during starts, stops, and rapid direction changes. That makes the unit suitable for compact axes that need responsive motion without the bulk of a larger frame.

Its mechanical envelope uses an 82 mm square flange and a 50 mm centering diameter for accurate mounting on the machine face. At standstill, the motor produces 2.7 Nm of continuous torque, which suits light feed axes that need steady force without excessive heating. Power and feedback cables exit through a connection box on side B, which keeps wiring clear of the load face and simplifies cable routing in tight spaces. The flange and pilot combination also helps maintain stable shaft alignment when the motor is fastened to a gearbox or machine plate. The housing carries an IP65 rating, and a shaft seal helps keep dust and low-pressure water jets away from internal parts. The winding insulation is built to Class F, allowing the stator to withstand elevated internal temperatures during continuous operation.

Integrated resolver feedback supplies multi-turn absolute position data beyond 4096 revolutions, with a maximum system error of ±8 angular minutes. Thermal limits permit continuous duty in ambient conditions from 0–40 °C without derating. The motor uses a plain shaft, which makes it easy to pair with timing pulleys, clamping hubs, or gear inputs that rely on frictional locking rather than a keyed connection. Because it is supplied without a holding brake, a vertical or suspended axis must rely on drive torque or an external clamp when power is removed. This arrangement is appropriate where the machine already provides a separate method for load retention.
