Product Description:

The MSK075D-0300-NN-S1-UG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It receives three-phase drive power and converts it into controlled torque and speed for automated machinery, supporting accurate positioning and repeatable motion cycles in assembly, printing, and material-handling lines. Its housing follows the standard series design, and the electrical interface uses a rotatable 240° encoder connector that helps route cables in compact control cabinets. This arrangement supports flexible installation where cable exits must avoid nearby machine structures or moving parts.

Cooling for this model relies on natural convection, so heat leaves through the motor surface without the need for auxiliary fans. Feedback is provided through a Hiperface interface, which lets the drive exchange position data and electronic nameplate information with the encoder system. The internal encoder operates with 128 signal periods, supporting smooth speed regulation and stable motion control. Its sensing element uses optical technology, which helps maintain accurate signal generation over normal operating temperature changes. The encoder is a single-turn design, so absolute position is retained within one mechanical revolution while additional turns are tracked by the control system.

An electrically released brake provides up to 23 Nm of holding torque, helping keep the axis secured when supply power is removed. This feature is useful on axes that must stay in place during shutdown or emergency stop conditions. Power is transmitted through a plain shaft, allowing the application to use a suitable coupling without a keyed connection. The motor has a frame size of 075 and a D length, giving it the physical envelope associated with this housing size. It uses winding code 0300, which matches the motor’s electrical characteristics to compatible drive settings for responsive servo operation.
