Product Description:
The MSK071C-0300-NN-M2-UP1-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it converts drive-controller commands into precise rotary motion for axes that require tightly regulated speed and position. Its compact C-length housing fits confined mechanical spaces, and the keyway shaft provides positive torque transmission to couplings or pulleys. The motor is intended for closed-loop servo applications where acceleration, holding, and repeat positioning are managed by the connected drive during normal machine cycles.
The motor is cooled by natural convection, so it relies on ambient airflow rather than forced fans, and continuous output depends on available heat dissipation. An enclosure rating of IP65 seals the frame against dust and low-pressure water jets, allowing installation on exposed machine sections without additional covers. For feedback, an optical multiturn encoder delivers 2048 signal periods per revolution, giving high-resolution position data, and its connector can rotate 240 degrees to ease cable routing. The brake can hold stopped shafts with 23 Nm of torque and is released electrically during motion. Winding designation 0300 identifies the resistance and inductance values expected by a matching IndraDrive amplifier. The increased concentricity design reduces radial runout during rotation.
Physical proportions follow size code 071, so the mounting face and pilot diameter match other motors in that frame class. Insulation system class 155 supports winding temperatures up to 155 °C, which helps the motor tolerate higher thermal stress during dynamic operation. Position information is transmitted through the digital EnDat2.1 interface, which provides absolute multiturn data and electronic nameplate storage for drive recognition and setup. Continuous service is intended in ambient temperatures of 0 to 40 °C. The encoder and brake combination supports stable axis control on packaging lines, feed systems, and gearbox-coupled applications.
