Product Description:
The MSK100B-0400-NN-S3-AP1-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat that belongs to the MSK IndraDyn S Synchronous Motors series. As a brushless AC drive, it converts controlled inverter power into precise rotary motion for positioning, packaging, and machining axes in industrial automation. The motor integrates an electrically released holding brake so that vertical or load-bearing shafts can be locked whenever power is removed. This arrangement supports controlled motion tasks that require accurate shaft positioning during normal operation and secure holding when the axis is stopped.
Cooling is provided by natural convection, so no external fan or liquid circuit is fitted and heat leaves the housing through ambient airflow. Position feedback travels over a Hiperface link that carries absolute angle and motor data on two differential conductors. Inside the encoder, a capacitive sensor produces commutation signals without optical disks. The electrically released brake provides 32 Nm of static holding torque and disengages automatically when the coil is powered. An enclosure rated IP65 blocks dust and water jets from the stator and hybrid connector during washdown service. This combination supports stable feedback transmission and reliable operation in enclosed machine spaces.
The encoder tracks a single mechanical turn in single-turn format, so systems that need multiturn data must perform drive-based homing. Power enters on the A-side of the frame, which helps when cable routing runs parallel to the machine bed. Class 155 insulation allows the copper windings to operate at elevated temperature, while continuous duty is limited to an ambient range of 0 to 40 °C. The motor uses size 100 with length code B, and the shaft has a keyway for positive torque transfer. Winding code 0400 matches the stator impedance to standard IndraDrive amplifiers, and the standard frame design keeps the housing compact by omitting external blowers.
