Product Description:

The MSK100A-0300-NN-S1-AG1-NNNN is an MSK IndraDyn S series synchronous motor manufactured by Bosch Rexroth Indramat. Supplied in the series’ standard mechanical design, the unit is intended for industrial automation tasks where a drive controller must deliver repeatable torque and velocity to a working axis. Natural air movement around the housing removes heat, so the motor can be installed in cabinets or on open machine frames without auxiliary fans. It is commonly used on packaging, handling, and indexing axes that require accurate acceleration and repeatable stopping.

Heat is carried away through natural convection, a cooling method that simplifies installation and eliminates fan noise or filter maintenance. Motion feedback is produced by an optical encoder that resolves the shaft position into 128 signal periods, which supports stable position control at the drive. The encoder communicates through the Hiperface interface, allowing feedback data to be transferred with reliable signal quality. An electrically released holding brake provides 32 Nm of static torque, so the axis can remain locked when power is removed. External surfaces and cable entries meet IP65, helping protect the motor from dust and low-pressure water jets. This combination of feedback and holding torque supports controlled stopping and restart behavior after interruptions.

The motor uses a plain shaft that mates directly with couplings or pulleys and avoids the imbalance that can come with keyed designs. Its winding and lubricant system remain stable within an ambient range of 0 to 40 °C, allowing continuous duty on typical factory floors. Insulation class 155 supports elevated winding temperatures during cyclic operation. Winding code 0300 identifies the electrical data matched to compatible MSK drives, while size 100 laminations and the compact A length help conserve installation space. The power connection is placed on the A-side for straightforward cable routing, and the encoder is single-turn, which suits machines that establish a fresh reference position during each operating cycle. Because the motor is self-cooled, surrounding airflow should remain unobstructed during continuous operation.
