Product Description:

The MSK101C-0300-NN-S1-AG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and delivered within the MSK IndraDyn S Synchronous Motors series. It functions as a compact, high-dynamic torque source for positioning axes, pick-and-place gantries, and similar motion stages that require precise velocity and torque regulation from a closed-loop drive system during rapid starts, stops, and repeated positioning moves. The design is standard, indicating the absence of specialized coatings or oversized bearings for unusual operating conditions.

Thermal management relies on natural convection, so no external fan or liquid circuit is required, which keeps the motor package simpler and influences geometry and installation clearances. The housing carries an IP65 rating that blocks dust ingress and water jets, matching the motor to floor-mounted machinery and enclosed production equipment. A plain shaft transmits torque directly to couplings or gearboxes, and the power connector is on the A-side for cable routing inside cabinets. Insulation class 155 sets the winding temperature class and aligns with the 0 to 40 °C ambient operating window. The motor has size 101 and length code C, while winding code 0300 identifies the electrical resistance and inductance set used for this variant.

Rotor position is monitored through the Hiperface feedback interface that uses an optical sensor. Its base resolution is 128 signal periods, and the data is delivered as a single-turn value to the drive, providing absolute position within one revolution for accurate commutation and axis control. Because the motor is supplied without a holding brake, any load-side arrest must be achieved by drive torque or an external mechanical lock. The lack of a brake reduces inertia, which helps the motor accelerate quickly without adding brake mass to the rotor.
