Product Description:

The MSK070E-0300-NN-S1-UG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This model is built to provide precise rotary motion for industrial automation axes such as packaging lines. Its compact frame makes it suitable for spaces where a cabinet-mounted drive must deliver rapid torque changes. The motor forms the electromechanical interface between the drive controller and the mechanical load, converting controlled three-phase current into exact angular displacement. The part number encodes the size, length, winding code, and brake configuration used in the assembly.

Thermal management relies on natural convection, eliminating the need for forced air or liquid circuits and allowing installation without additional cooling hardware. Position data are transferred through a Hiperface optical encoder that delivers 128 signal periods per revolution, enabling fine position interpolation inside the drive. The encoder housing is rotatable through 240°, so the cable outlet can be aligned with the cabinet layout. An electrically released holding brake supplies 23 Nm of static torque, permitting vertical axes to remain locked when power is removed. The housing meets the IP65 ingress standard, sealing the windings against dust and low-pressure water jets for general plant floor conditions.

Mechanical sizing follows the 070 frame with the E length and winding code 0300, balancing inertia and torque density for medium-power tasks. The design classification is standard, so the motor uses standard mounting accessories. Encoder feedback is of the single-turn variety, making position tracking available within one mechanical revolution. Continuous operation is permitted within 0–40 °C ambient limits, and the motor is insulated to class 155 to tolerate elevated winding temperatures without premature aging. A plain shaft interface minimizes backlash in direct-coupled loads while keeping the cooling arrangement simple.
