Product Description:
The MSK070C-0150-NN-S2-UP1-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a servo actuator, it works with IndraDrive controllers to convert commanded current into accurately regulated rotary motion. That arrangement suits pick-and-place robots, packaging stations, and gantry axes that require fast response and stable positional accuracy in industrial automation lines. In closed-loop operation, the motor supports coordinated acceleration, deceleration, and settling behavior on axes that change direction frequently.
As a fanless unit, cooling relies on natural convection, so surrounding airflow affects the motor’s temperature during continuous or repetitive duty. The aluminum housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal motor parts. Frame code 070 indicates a 70 mm flange diameter, while length designation C gives the motor a longer body for higher continuous torque in the same mounting footprint. Class F insulation rated at 155 °C protects the windings from thermal stress, and winding code 0150 matches phase impedance to typical 400 V drive systems. The keyed steel shaft is built with increased concentricity for smooth coupling to gearboxes, and the motor operates in ambient temperatures from 0 °C to 40 °C.
The feedback system uses an optical encoder with EnDat2.1 communication and a resolution of 2048 signal periods per mechanical turn. Because it is a single-turn encoder, it retains the absolute shaft position within one revolution, while the drive tracks additional turns electronically. This feedback format supports accurate commutation and repeatable positioning during short indexing moves and repeated reversals. The plug-in encoder connector can rotate through 240°, which helps align the cable with the machine layout and reduces routing strain. For static holding, an electrically released brake provides 23 Nm of torque to resist drift on vertical or indexing axes when power is removed.
