Product Description:

The MSK040B-0450-NN-M3-UP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts commanded electrical input from a drive into controlled rotary motion, allowing precise positioning or velocity regulation in automated assembly lines, packaging equipment, and similar machinery. By pairing precise feedback with its drive, the motor acts as an electromechanical actuator that replaces pneumatic or hydraulic solutions where accuracy, repeatability, and clean operation are required in industrial automation environments.

The motor uses natural convection cooling, so heat leaves the housing through surface radiation and airflow without external fans. Frame size 040 and length code B give the motor a compact geometry, while winding code 0450 corresponds to a voltage-speed combination suited to medium-power axes. Position feedback travels over the Hiperface interface; inside the encoder, capacitive sensing generates 16 signal periods per revolution, and the system tracks multiple turns through its multiturn absolute architecture. A rotatable 240° connector lets the feedback cable exit in the preferred direction during installation. The motor is supplied without a holding brake, so applications that must maintain position at power-off require an external locking device.

Sealing at the junctions and across the housing provides an IP65 rating, enabling dependable use where airborne dust or directed water jets are present. The thermal system is limited to an ambient range of 0 to 40 °C, and the passive cooling path keeps the windings within class 155 limits during continuous duty. Mechanical power leaves through a shaft with keyway that transmits torque to gearboxes or pulleys without slip. This layout suits compact servo axes that need protected motor surfaces, absolute position feedback, and flexible cable routing in tightly spaced machine sections.
