Product Description:

The MSK070C-0300-NN-S1-UP0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as the primary motion element in automated stations, converting regulated three-phase power from a Rexroth drive into precise shaft rotation. By delivering controllable torque and position feedback, the motor supports coordinated movement on packaging machines, pick-and-place gantries, servo presses, and other process equipment that require repeatable positioning in high-cycle material-handling lines.

Heat dissipation is handled by natural convection, so the housing must remain unobstructed to let ambient air carry away winding losses. For flexible cable routing, the feedback plug uses a 240° rotatable connector that can be indexed during installation without tools. Position data travels through the bidirectional Hiperface protocol, which combines incremental and absolute channels in one set of conductors. Inside the encoder, a glass scale delivers 128 signal periods per revolution, and the sensing path is optical, which helps resist electrical noise and maintain stable feedback quality during operation.

The feedback system is single-turn, so absolute position is retained within one mechanical rotation and resets beyond that point. Drive torque reaches the load through a shaft with a keyway, providing positive engagement for couplings or gears. The motor has a frame size of 070, which matches the flange outline and bolt circle used in this motor family. It also uses winding code 0300, which corresponds to the electrical characteristics expected by compatible Rexroth drives. The unit has a standard design layout, is supplied in length C, and comes without a holding brake, so the axis must be secured by external braking or servo holding torque when power is removed.
