Product Description:

The MSK101E-0300-FN-S2-AG2-RNNN servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is an electromechanical actuator intended for industrial automation tasks where tightly controlled torque and rapid feedback are needed to position machine axes, packaging heads, or transfer stations. Its design pairs with IndraDrive power stages so that the drive can command high-resolution motion while the motor’s internal encoder returns precise position data to close the control loop.

Heat removal is handled by an integrated liquid cooling circuit that mates with the FN cooling plate. Continuous coolant flow keeps the stator below permissible temperature even during peak power cycles. Rotor position is captured by an EnDat2.1 optical encoder that produces 2048 signal periods per revolution, and this resolution supports very precise positioning. The encoder is a single-turn type, supplying the absolute angle within one mechanical turn without multi-turn counting. For load holding or safe standstill, an electrically released brake supplies 70 Nm of static torque, allowing the axis to stay locked when the machine is de-energized.

The motor has a motor size 101 housing and length code E, giving it a compact body while still allowing space for the active winding section. The shaft is a plain shaft, so it is intended for external couplings that do not require a key. The electromagnetic layout uses the 0300 winding code, which matches the electrical characteristics expected by compatible drive settings for high-current operation. All power conductors exit through the power connector on the A-side, which helps simplify cable routing when multiple axes are installed close together. The stator lamination stack is built with increased concentricity to help reduce cogging during rotation.
