Product Description:

The MSK070C-0300-NN-S2-UP0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Within an automation cell, it couples to an IndraDrive controller and converts regulated current into precise torque and speed for positioning tables, pick-and-place arms, or packaging axes. The motor’s compact form factor and electronic feedback allow closed-loop motion without the mechanical slip associated with stepper arrangements.

Cooling is handled by natural convection, meaning the housing radiates heat to the surroundings with no external fan. The stator is machined for increased concentricity, limiting shaft runout when coupled to precision gearboxes. A shaft with a keyway transmits torque directly to keyed couplings. For flexible cable routing, the feedback connector is rotatable through 240°, so the plug can be turned to clear obstructions. Inside, a digital EnDat2.1 interface links the motor’s absolute encoder to the drive. That encoder resolves motion into 2048 signal periods per revolution, allowing the controller to interpolate fine positional increments and maintain tight velocity loops.

The sensing head uses an optical scanning principle that minimizes electrical noise. It is organized as a single-turn system, returning an absolute angle for each revolution without internal multi-turn gearing. The unit ships without a holding brake, which lowers rotating mass in the size-070 frame and simplifies maintenance for vertical axes that already use external brakes. Motor length code C and winding code 0300 establish the electrical constant and active stack height so designers can match voltage and inertia across machines while keeping encoder orientation, connector rotation, and passive cooling identical from build to build.
