Product Description:
The MKD041B-058-GP1-KN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended to supply controlled rotary motion for positioning axes, pick-and-place modules, and other automated stations that rely on precise torque regulation. Its synchronous design supports accurate speed control and stable torque response during repeated motion cycles.
A mounting flange of 82 mm establishes the interface to the machine frame, while the centering pilot of 50 mm aligns the stator concentrically with the driven mechanics. Power and feedback leads enter through a connection box situated on side B of the housing, which simplifies lateral cable routing. Output torque is transferred through a shaft with keyway, so pulleys or couplings can be locked without slip. The enclosure carries an IP65 rating that blocks dust ingress and water jets encountered in typical factory environments, and its windings use class F insulation to tolerate elevated internal temperatures. At standstill, the motor can deliver 2.7 Nm continuously, supporting static loads without overheating. Speed and position data are generated by resolver feedback, which provides analog sine-cosine signals suited for rugged industrial feedback loops.
A spring-applied brake generates 2.2 Nm of holding torque, preventing back-driving when power is removed and eliminating the need for external clamps on vertical axes. The integral shaft seal helps block lubricant leakage and protects the bearings in washdown cells. Operation is specified for ambient ranges of 0–40 °C, allowing cabinet-free mounting inside standard production halls. Length code B and frame size 041 give the motor a compact package that pairs with drives parameterized for winding code 058. For motion sequences that require tight commutation accuracy, the resolver and drive combination achieves a system precision of ±8 angular minutes, supporting repeatable positioning in automated assembly and light machining applications.
