Product Description:

The MSK070E-0300-NN-S3-AG0-NNAN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and offered within the MSK IndraDyn S synchronous motors series. Designed for installation on modern CNC or packaging lines, the unit receives three-phase power from an IndraDrive inverter and produces tightly regulated torque and speed that keep motion profiles aligned with PLC commands. Its reduced runout shaft geometry supports repeatable tool or load placement in demanding multi-axis assemblies. The motor is suited for coordinated positioning, indexing, and speed-controlled transport tasks where stable response is required during frequent starts and stops.

Thermal management relies on natural convection, so the housing dissipates heat without auxiliary fans or liquid circuits, and duty cycles must stay within the motor’s continuous torque limits. Positional feedback is exchanged over the Hiperface digital interface, allowing the drive to read absolute rotor position after power-up. Inside the encoder, one revolution is subdivided into 16 signal periods, and the rotor angle within each period is resolved electronically for smooth commutation. This sensor uses capacitive measuring technology, making it insensitive to magnetic fields that could distort conventional resolvers. The motor is sealed to IP65, which prevents dust ingress and withstands water jets, enabling direct mounting in wash-down machine zones. Frame size 070 and length code E set the motor’s mechanical envelope for installations that need a compact but comparatively long housing.

Mechanical holding force must be provided externally because the motor is supplied without a holding brake, so vertical axes must secure loads through the drive or a separate brake module. Continuous operation is specified for ambient temperatures from 0–40 °C, which suits typical cabinet-free machine layouts. A plain shaft couples to clamping hubs or shrink discs, while the power connector sits on the A-side to simplify cable routing along the machine base. Class 155 insulation permits winding temperatures up to 155 °C, and winding code 0300 identifies the electrical resistance and inductance profile used by the drive. The single-turn encoder architecture supplies one absolute position per revolution for homing-free starts, which helps shorten machine startup after a power cycle.
