Product description

Bosch Rexroth MKD041B-144-KP1-KN is a permanent-magnet digital AC synchronous servo motor from the MKD range for precise positioning, feed and handling axes. The exact version is also identified by Bosch Rexroth material number R911262307. The motor has size 041, length B and winding code 144. Its documented operating data includes 2.7 Nm standstill torque, 7.5 A standstill current, 34 A peak current and a maximum speed of 7,500 U/min. Heat is dissipated by natural cooling, and the specified motor weight is 4.4 kg. Position feedback is provided by a resolver with an integrated multiturn absolute encoder. Mechanically, this variant has a keyed shaft to DIN 6885-1 with a shaft seal. The integrated holding brake provides 2.2 Nm. Power is connected through a terminal box. This combination is essential for clear identification because adjacent MKD041B variants may differ in winding, feedback, shaft, brake or connection direction. During replacement, the complete type number and material number as well as the electrical and mechanical features must match the installed motor and machine configuration. The drive-controller parameters, permitted cables, installation conditions and axis load data must also be considered. The motor is suitable for targeted repairs, retrofit projects and spare-parts stocking in machine tools, packaging equipment, assembly systems and other industrial production machinery. Its documented resolver feedback and holding brake support applications in which position and axis state must be held under control. The unambiguous variant designation helps maintenance teams make a dependable match and prevents confusion with similarly named MKD motors.
