Product Description:
The Bosch Rexroth Indramat MSK100A-0300-NN-S2-BP1-RNNN is a servomotor in the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled rotary motion for precise positioning, velocity, and tension control on packaging stations, gantry axes, and general factory automation equipment. The model is intended for use with IndraDrive controllers that require advanced servo loops and integrated safety. This makes it suitable for indexing, web handling, and coordinated transfer motions that depend on consistent speed control.
Mechanically, the motor is built on size 100 stator laminations with the compact A-length housing, and its winding code 0300 matches compatible IndraDrive controllers. Cooling is by natural convection, so heat is dissipated through the housing surface without external blowers. The enclosure carries an IP65 rating, keeping internal components sealed against dust ingress and low-pressure water jets. Operation is specified from 0–40 °C, supporting rated performance in normal industrial conditions. Position feedback is delivered by an optical encoder that supplies 2048 signal periods over one mechanical revolution and communicates through the EnDat2.1 interface, allowing high-resolution commutation and electronic data storage. The increased concentricity design reduces radial runout, and the power connector is located on the B-side to simplify cable routing where side entry is preferred.
The electrically released brake delivers 32 Nm of static torque, allowing the axis to remain motionless when supply power is removed. Because the feedback system stores only a single-turn value, applications that need absolute position over multiple revolutions require a reference move after startup. Torque is transferred through a shaft with a keyway, which helps prevent slippage under load and supports secure coupling to driven components. Insulation class 155 permits winding temperatures up to 155 °C, providing thermal headroom during short duty peaks. In applications with suspended loads or frequent stops, the brake can keep the mechanics in place while the drive is disabled.
