Product Description:
The MSK101E-0300-NN-S2-LG0-RNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Designed to translate electrical commands into precise rotary motion, it provides closed-loop positioning and velocity control for packaging lines, gantry axes, and general motion platforms in automated plants. Integrated sensor feedback lets the connected drive monitor rotor position continuously and correct motion as load conditions change. The compact stator and rotor assembly helps the motor fit dense machine layouts where responsive axis control is required. That operating profile suits machines that accelerate, stop, and return to commanded positions many times during a production shift.
Cooling relies on natural convection, so heat leaves the housing surface without external fans. With no fan assembly to mount around the motor body, surrounding machine space can remain less crowded. Feedback is provided through an EnDat2.1 optical interface that transmits absolute position data with 2048 signal periods per revolution, giving the drive fine interpolation for speed and position control. The encoder uses an optical measuring principle and is a single-turn design, so position is resolved within one mechanical revolution and can be read directly by the control system after startup. The motor is supplied without a holding brake, so any stationary load that must remain fixed during power-off conditions requires external retention.
The motor has an IP65 housing, a plain shaft, and a power connector on the left side, which supports straightforward installation in enclosed machine spaces and helps route cables away from nearby structures. The plain shaft is intended for clamping-style couplings rather than keyed torque transmission. Continuous duty is permitted at ambient temperatures from 0 to 40 °C. Class 155 insulation, winding code 0300, and length designation E support thermal performance that matches the intended drive current. The size 101 frame also uses increased concentricity to reduce radial runout at the coupling and help maintain smooth tracking during rapid indexing.
