Product Description:
The MSK070D-0300-NN-M3-UG1-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical drive commands into precise rotary motion for packaging lines, gantries, and other CNC axes that require accurate speed and position control. The motor is intended for closed-loop operation with a compatible drive controller, and its single-cable arrangement carries both motor power and feedback signals to reduce external wiring. In automated machinery, this supports repeatable axis movement during positioning, indexing, and synchronized travel. Direct torque generation at the shaft also helps the drive respond quickly to changing motion commands.
Cooling is handled by natural convection, so heat leaves the housing through the outer surface without a fan. The motor uses a plain shaft for coupling to gearboxes or belt-driven mechanisms, while feedback is transmitted through a Hiperface interface on the same cable path. Its encoder uses capacitive sensing and a multi-turn absolute format with 16 signal periods, allowing the drive to retain position information across multiple revolutions. This feedback method supports immediate position availability after power-up and avoids a separate homing cycle in many applications. An electrically released brake provides 23 Nm of holding torque when power is removed, which helps keep vertical or suspended loads from drifting at standstill.
The motor has size 070 and length code D, placing it in a compact frame with a longer stack length for this series. Winding code 0300 gives the electrical values expected by matching IndraDrive power stages. This combination helps the motor fit machines that need responsive motion without forced cooling hardware. A 240-degree rotatable connector allows the cable outlet to be positioned after mounting, which helps when space around the motor is limited. The unit also follows the standard design code used for this motor line.
