Product Description:
The MSK071E-0200-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit converts drive controller output into precise rotary motion, making it suitable for indexing tables, form-fill-seal equipment, and articulated axes that require accurate torque delivery. In closed-loop systems, it responds to changing speed and position commands so the axis can accelerate, settle, and reverse with controlled behavior. Its 071 frame diameter and E-length housing keep the motor compact while providing enough rotor inertia for smooth motion profiles during repeated starts, stops, and speed changes. This layout is useful where installation space is limited but repeatable motion is still important.
Heat is removed through natural convection, so no external blower or liquid loop is required and the aluminum housing dissipates heat passively. The housing has an IP65 rating that blocks dust and low-pressure water jets, which supports installation in demanding industrial areas. Position feedback comes from an optical encoder with EnDat2.1 communication and 2048 signal periods per revolution, giving the connected drive accurate position data for speed and commutation control. Because the encoder is single-turn, absolute position is available within one mechanical revolution, which is suitable for axes that return to a reference position during startup. The sensing head can rotate 240° to simplify cable routing where nearby guards, machine frames, or neighboring axes limit connector access.
The servo uses a plain shaft for clamp hubs or shrink discs and is supplied without a holding brake, so external means must hold the axis when power is removed. Rated operation applies at ambient temperatures from 0 to 40 °C, and insulation class 155 supports the motor's thermal load during normal service. Winding code 0200 identifies the stator's electrical characteristics for use with compatible MSK drive amplifiers. This arrangement is well suited to machine sections that rely on friction-lock couplings instead of keyed connections. It also fits applications where the axis does not need an integrated brake for static load holding.
Frequently Asked Questions about MSK071E-0200-NN-S2-UG0-RNNN:
Q: How is the MSK071E-0200-NN-S2-UG0-RNNN servo motor cooled?
A: The MSK071E-0200-NN-S2-UG0-RNNN motor uses natural convection for cooling, operating effectively without forced ventilation.
Q: What type of encoder and resolution does the MSK071E-0200-NN-S2-UG0-RNNN include?
A: This model features an optical singleturn encoder with EnDat2.1 interface, providing 2048 signal periods for precise position feedback.
Q: What level of environmental protection does the MSK071E-0200-NN-S2-UG0-RNNN offer?
A: The motor has an IP65 protection rating, making it highly resistant to dust and low-pressure water jets.
Q: Does the MSK071E-0200-NN-S2-UG0-RNNN include a holding brake?
A: This variant comes without a holding brake, so the shaft is not held in place when unpowered.
Q: What type of shaft and design are provided on the MSK071E-0200-NN-S2-UG0-RNNN motor?
A: The MSK071E-0200-NN-S2-UG0-RNNN is built with a plain shaft and features increased concentricity for enhanced shaft precision.
