Product Description:

The MSK071E-0450-NN-M1-UP1-NSNN is a synchronous servomotor from Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. As a drive element, it converts electrical energy into controlled rotational motion for positioning axes and speed-regulated spindles in industrial automation. The motor uses a standard housing that also meets explosion-protected construction requirements, allowing use in areas where hazardous gases may be present. Its size 071 construction and E-length frame support a mid-range torque output suited to packaging machinery, material handling systems, and machine tools.

Heat leaves the stator through natural convection, so no external blower or liquid circuit is needed, and clear mounting space helps maintain the temperature profile. The enclosure carries an IP65 rating, which blocks dust ingress and resists low-pressure water jets for direct mounting outside cabinets. Continuous service is permitted in ambient conditions from 0 to 40 °C, helping the motor stay within its thermal range during normal operation. An electrically released holding brake provides 23 Nm of static torque to keep vertical loads secure when the drive is de-energized. For simpler cable routing, the hybrid encoder-motor connector can be rotated through 240° to align the cable exit with the machine layout.

Feedback is transmitted through a Hiperface interface that carries position, speed, and identification data to the drive. The sensing system is optical and operates as a multiturn absolute encoder with 128 signal periods, so the controller receives high-resolution information over multiple mechanical revolutions without battery backup. Mechanical power is transferred through a keyed shaft, which helps prevent slip during start-stop cycles. Winding code 0450 indicates the electrical resistance and inductance used with compatible IndraDrive amplifiers, and insulation class 155 sets the permissible winding temperature ceiling.
