Product Description:

The MSK100B-0300-NN-M2-AG2-RNNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servo motor intended for precise speed and position control in automated machinery. The motor converts drive commands into controlled rotary motion for positioning axes, feed systems, and other servo applications that require repeatable movement. This model uses motor length B and motor size 100. It is supplied with a power connector on the A-side to simplify cabinet routing.

The housing carries a protection rating of IP65, so it resists dust and water jets during normal industrial wash-downs. Heat is removed by natural convection, eliminating the need for external fans. An increased concentricity design helps reduce runout when the shaft is coupled to precision gearboxes or other accurately aligned drive components. Position data are delivered through a Bosch Rexroth optical encoder that uses the EnDat2.1 interface; it provides 2048 signal periods per revolution and supports a multiturn absolute format so the drive can retain position information across power cycles. Winding code 0300 is matched to this feedback arrangement for use with the associated IndraDrive amplifier.

An electrically released holding brake supplies 70 Nm of static torque for vertical axes that must resist back-driving at rest. The rotor exits the housing through a plain shaft interface that simplifies couplings where keyways are unnecessary. Continuous operation is specified from 0 to 40 °C. Within this range, the Class F insulation system has a thermal index of 155, which helps protect winding life under full load. This combination is suitable for axes that remain energized during normal production cycles and require holding torque when stopped.
