Product Description:

The MSK071C-0300-NN-S1-UP0-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed-control tasks in automated machinery, where precise torque output must be combined with a compact motor design. The unit belongs to motor size 071 with length code C, so it fits mid-frame drive axes without taking excessive installation space. In operation, it converts inverter current into mechanical rotation for couplings, pulleys, and other driven machine elements.

Thermal management relies on natural convection, so heat leaves the housing through its surface without the need for an external fan. The housing has an IP65 rating, which protects internal parts against dust and against water jets during normal machine use. Position feedback is transmitted through the Hiperface protocol, allowing the drive controller to receive absolute position data and electronic nameplate information. The encoder generates 128 signal periods per revolution, and interpolation allows the control loop to work with finer position resolution. The motor operates in an ambient temperature range of 0 to 40 °C, allowing rated performance when surrounding air stays within that range.

The feedback unit uses optical scanning and is built as a single-turn device, so it reports the rotor angle within one mechanical revolution. Mechanical output is transmitted through a shaft with a keyway, which provides a positive drive connection for mounted transmission components. The winding uses insulation class 155, allowing winding temperatures up to 155 °C during operation. A rotatable 240° encoder connector helps with cable routing, and the motor is supplied without a holding brake. Winding code 0300 is matched to standard IndraDrive current characteristics for this motor type.
