Product Description:
The MSK075E-0450-NN-M1-UG1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It converts commanded current into precise rotary motion for positioning tables, packaging axes, and other automated machinery that depend on accurate speed and torque control. Its servo design supports fast response during acceleration, deceleration, and holding tasks, so it can be used on axes that must repeat the same motion path while remaining stable under changing load conditions.
Heat is removed by passive natural convection, so no external fan or liquid jacket is required. Because cooling relies on the motor housing and surrounding air, the installation stays simpler and avoids additional hoses or blower components. The housing carries an IP65 rating, which helps protect internal parts from dust and low-pressure water jets during normal industrial use. An electrically released holding brake supplies 23 Nm of static torque, helping vertical or suspended axes remain in place after power is removed. Position feedback comes from a Hiperface optical encoder with 128 signal periods per mechanical revolution, and the encoder connector can rotate through 240° to simplify cable routing where enclosure space is limited.
The motor uses frame size 075 with length code E, giving it a compact flange that fits common planetary gearboxes and similar machine interfaces. It has a plain shaft, so clamp or shrink-fit couplers can be installed without a keyway, which suits direct transmission layouts that rely on friction locking. Continuous service is supported in ambient temperatures from 0 to 40 °C, and insulation class 155 permits winding temperatures up to 155 °C before thermal protection must intervene. A multiturn absolute encoder stores rotor angle over multiple revolutions, which lets the drive retain position information beyond a single turn. The winding layout is matched for compatible drive parameter settings during cyclic duty and steady servo operation.
