Product Description:

The MSK100B-0400-NN-S1-BP0-NNNN Synchronous Motor ensures efficient torque control and consistent performance. It offers reliable operation in demanding working environments. This model is equipped with an integrated optical encoder.

This MSK100B-0400-NN-S1-BP0-NNNN synchronous motor provides a maximum speed of 4500 min⁻¹ and a peak torque of 102.0 Nm. Its continuous torque at standstill at 100 K reaches 33.0 Nm. The motor uses natural convection for cooling. It features a robust shaft with keyways and a sealing ring to support mechanical reliability. The motor enables smooth rotational output with improved stability with a total of 4 pole pairs. The encoder integrated in the motor is a singleturn optical encoder offering 128 increments to ensure accurate feedback. The maximum current draw of the motor is 106.7 A while the continuous current at standstill on the surface is 35.6 A. The thermal time constant is 40.0 minutes that supports stable thermal management during extended operation. The motor’s winding inductivity is measured at 3,100 mH. Its sound pressure level remains below 75 dB [A] that allows operation within noise sensitive environments. This model is enclosed in an IP65 rated housing. This rating protects the motor from dust and water jets. This MSK series motor is well suited for machine tools and automation lines requiring consistent speed and torque control.

The Bosch Rexroth MSK100B-0400-NN-S1-BP0-NNNN synchronous motor operates in ambient temperatures from 0 to + 40 °C. It has a continuous current rating at standstill of 30.8 A at 100 K. The motor weighs 36.0 kg that supports stable installation and reduced vibration. The combination of high torque capacity and encoder feedback allows this motor to perform precisely in automation systems. Its electrical and mechanical design supports accurate motion control across varied industrial applications.
