Product Description:

The MSK070D-0300-NN-M1-UG0-NSNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated production cells, it supplies tightly regulated torque and speed to rotary axes that handle positioning, feeding, or indexing tasks. The sealed motor housing combines the mechanical drive element with the encoder and power connections, giving the controller a compact servo package for precise motion. This layout supports predictable axis response in machines where available installation space is limited.

Thermal management relies on natural convection, so heat leaves the frame through passive dissipation rather than fan-assisted airflow. Position data is transmitted through the Hiperface interface, and the encoder provides 128 signal periods per revolution together with multiturn absolute position retention after power is removed. The feedback connector can rotate through 240 degrees to ease cable routing in tight installations and reduce strain at the entry point. The motor is supplied without a holding brake, so any vertical or suspended load must be secured by the drive or an external device when the axis is stopped. Because cooling is passive, there are no fan components inside the motor housing.

With an IP65 housing, the motor resists dust and low-pressure water jets during normal industrial use. It maintains specified performance in ambient temperatures from 0-40 °C, and the encoder uses an optical scanning method for stable position signals at higher speeds. Insulation class 155 allows the windings to tolerate elevated operating temperatures within the motor's thermal design. The unit has size 070, length D, a plain shaft suited to clamp couplings, and winding code 0300 for use with matching drive modules. That shaft style is useful where a simple, direct connection to a hub or gear stage is preferred.
