Product Description:

The MSK071E-0300-FN-M2-UG1-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat and positioned within the MSK IndraDyn S Synchronous Motors series. It is installed on closed-loop motion axes where it converts commanded current into precise rotary displacement for automated packaging, handling, and assembly equipment. The motor has a plain shaft, frame size 071, E length, and winding code 0300 for medium-power, high-dynamics drive tasks.

The motor employs liquid cooling, so heat is removed by a coolant circuit rather than ambient air, keeping winding temperature stable during sustained load. Its housing carries an IP65 rating, meaning dust cannot enter and low-pressure water jets do not interfere with operation. Shaft position is captured by an optical encoder that delivers 2048 signal periods per revolution; the resulting fine pulse spacing supports accurate velocity and position loops. Feedback is exchanged over the EnDat2.1 interface, which provides digital bidirectional data and automatic parameter storage, and the encoder provides multiturn absolute position information so the controller retains position after power loss.

The electrically released holding brake delivers 23 Nm of static torque to secure vertical or suspended loads whenever the drive is disabled. Cable routing is simplified by a connector that can be rotated through 240°, allowing the feedback plug to clear nearby hardware without strain. Manufacturing to an increased concentricity tolerance reduces radial runout and associated force ripple at low speed. Windings use class 155 insulation, permitting operating temperatures up to 155 °C without loss of dielectric strength. Continuous service is specified for ambient conditions between 0 °C and 40 °C, and the plain shaft arrangement minimizes axial assembly forces on couplings and gearheads.
