Product Description:
The MSK070E-0300-NN-M3-AG0-NNAN is a synchronous servomotor supplied by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks in industrial automation where repeatable positioning and rapid speed changes are required across packaging, material-handling, and assembly equipment that relies on consistent servo response. Its synchronous motor design supports precise response to changing speed and position commands during cyclic machine operation, which is useful on axes that must accelerate, settle, and repeat without drift.
The motor’s frame code of 070 indicates a 70 mm flange size that fits compact mechanical layouts, while the E length extends the stack to raise continuous torque. Cooling relies on natural convection, so heat leaves the housing without fans or liquid circuits, simplifying cabinet airflow planning. A plain shaft is provided for backlash-free coupling through shrink disks or tapered hubs. The enclosure carries an IP65 rating, keeping it dust-tight and protecting it against low-pressure water jets on factory floors. Power is routed through an A-side connector to keep cable bends away from adjacent axes. Rotor accuracy benefits from the Reduced Run-Out design, which helps minimize radial error when the motor is paired with precision gearheads. Feedback travels over the Hiperface digital link, and the integrated capacitive sensor delivers multi-turn absolute position data so the axis controller knows shaft angle after power cycles. There is no holding brake, so stopping and load holding must be provided by the drive or external mechanics.
An encoder resolution of 16 signal periods per revolution supports fine interpolated positioning when combined with drive electronics. Winding code 0300 corresponds to resistance and inductance values matched to compatible MSK drives for rated current delivery across the 0 to 40 °C ambient range. Class 155 insulation tolerates winding temperatures up to 155 °C, allowing full torque without premature varnish aging during continuous industrial duty.
