R911321452
The R911321452 (MSK040B-0450-NN-M1-UP0-NNNN), an industrial automation piece produced by Bosch Rexroth Indramat, belongs to the IndraDyn S synchronous motor series. This motor is used across diverse industrial arenas including machine tools, metal forming machinery, and robotics. With its rotatable (270 degrees) power connector, it establishes an AC 3 × 400 – 480 V power connection with a compatible drive controller. The synchronous motor is notable for its operational reliability under its intended temperature of 20 degrees Celsius, outputting a consistent torque of 1.26 Nm/A at a constant voltage of 77.8 V/rpm. The MSK synchronous motor additionally houses a rotor balanced with a full key and comes in an ATEX standard-approved housing shielded under the IP65 protection standard.
The R911321452 (MSK040B-0450-NN-M1-UP0-NNNN) does not include a holding brake, but instead, a multiturn optical encoder is used for speed and position control of the AC motor. It cools naturally to manage its ambient temperature and has four pole pairs. The component has a discharge capacity of 1.3 nF and a thermal time constant of 13 minutes, ensuring reliable operation under ambient temperatures ranging from 0 to +40 degrees Celsius. The insulation class of the motor is 155, and it is available for order from Servo Suppliers for direct delivery.
