Product Description:

The MSK071D-0300-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With frame size 071 and length code D, it suits medium-inertia axes that require repeatable rotary motion in packaging, printing, and handling equipment. The rotor and stator use an increased concentricity design that limits runout and keeps vibration low during rapid speed changes. A plain shaft facilitates direct coupling, and the motor is supplied without a holding brake, so static load retention must be provided by an external clamp or drive torque.

Heat is removed by natural convection, so installation spaces must allow unobstructed airflow around the housing to keep winding temperature within Class 155 limits. Feedback and power wiring are simplified by an encoder connector that is rotatable through 240°, permitting cable exit in several directions inside a crowded cabinet. Position data travel over the EnDat 2.1 digital interface, and its optical scanning system resolves motion into 2048 signal periods per mechanical turn. Because the sensing system is configured as a single-turn device, the drive derives absolute shaft position for one revolution and must perform homing if multi-turn information is required. The optical technology yields low jitter and supports high control-loop bandwidth.

The motor housing carries an IP65 rating, blocking dust ingress and water jets when gaskets and cable glands are correctly seated. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, so higher enclosure temperatures can reduce cooling margin. Class 155 insulation withstands sustained winding temperatures associated with cyclic duty. Winding code 0300 identifies the electrical configuration used by drive setup tools to select current limits and commutation parameters.
