The Bosch Rexroth Indramat MKD041B-144-FG1-KN is a high-precision servo motor in the MKD Synchronous Motors series, designed to deliver dynamic motion control with robust resolver feedback. Manufactured by Bosch Rexroth Indramat, this product type features a peak torque of 14.1 Nm and a rated torque of 3.5 Nm, providing reliable output across a broad range of applications. The motor operates within an ambient temperature of 0°C to 40°C, ensuring stable performance in standard industrial environments. With an IP65 protection class and natural convection cooling, the MKD041B-144-FG1-KN resists dust and moisture ingress for maintenance-free operation. This model is ideally suited for precision automation tasks where accuracy and durability are critical.



Detailed technical specifications underline the motor’s versatility. The MKD041B-144-FG1-KN employs a resolver feedback system for high-resolution position sensing and features a plain shaft with shaft seal rings. The unit includes a holding brake with a brake torque of 2.2 Nm at 0.34 A, enabling secure stopping. The continuous torque at standstill of 2.7 Nm and motor length code B reflect its compact yet powerful design. A 50 mm centering diameter and IM B5 flange mounting ensure straightforward integration, while the connection box supports a standard power connection. The winding code 144 indicates optimized coil configuration for repeatability and low electrical noise.



Operational performance is optimized for demanding cycles. The motor achieves a maximum speed of 7500 rpm under peak conditions with a corresponding peak current of 34 A. It delivers continuous power of 0.55 kW at 3000 rpm and 0.88 kW at 4500 rpm, meeting diverse torque-speed requirements. Natural convection cooling removes heat without additional fans, keeping the housing temperature rise within safe limits. Weighing just 4.4 kg, the MKD041B-144-FG1-KN offers an excellent power-to-weight ratio for agile motion systems. Continuous torque generation is supported even with a 60 K rise in housing and a 100 K rise in winding temperature.



System integration is facilitated via the built-in resolver feedback interface and standard electrical connections through the B-side junction box. The motor accepts 115–170 V input at 150–225 Hz when paired with compatible drive controllers. This flexibility suits a wide range of automated equipment in machine tools, paper processing, food packaging, and material handling systems. The precision, environmental resilience, and integrated brake functions make the MKD041B-144-FG1-KN an ideal component for next-generation industrial automation solutions.
