Product Description:

The MSK075E-0300-FN-S1-BG1-NNBN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S motor, it converts drive current into precise rotary motion for positioning axes in packaging, printing, and material-handling equipment. The unit combines the motor, encoder, and brake in one housing, which supports compact installation and closed-loop speed and torque control in automated production systems. This integrated layout also reduces the number of separate external components needed around the axis.

Liquid cooling removes heat directly from the stator jacket, so the motor can maintain stable output in enclosed installations. Rotor position feedback comes from an optical single-turn encoder that communicates over the Hiperface interface and provides 128 signal periods per revolution for commutation and position tracking. An electrically released brake supplies 23 Nm of holding torque to secure vertical loads when power is removed. The housing has an IP65 rating, which helps prevent dust ingress and protects the motor from water jets in industrial environments.

The mechanical interface uses a plain shaft that pairs with backlash-free couplings, and power is routed through a connector on side B to keep cable runs along the service edge of the machine. The electromagnetic design uses winding code 0300 and insulation class 155, which supports continuous thermal operation in demanding servo applications. A compact stator built to motor size 075 with length code E provides high torque density without increasing the mounting footprint. The motor operates in an ambient temperature range of 0-40 °C, which suits typical factory conditions. This combination of shaft style, cooling method, and encoder feedback makes the motor suitable for responsive axis control where accurate positioning and dependable holding capability are required.
