Product Description:
The MSK040C-0450-NN-M1-UG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts electrical power from a drive controller into controlled rotary motion for machines that demand accurate positioning, speed following, and rapid acceleration in automated assembly lines, packaging equipment, and light machining centers. The unit interfaces directly with IndraDrive amplifiers and fits into small mechanical envelopes because of its slim stator diameter.
Cooling for this motor is handled by natural convection, so heat is carried away through the housing surface without external fans or liquid circuits. The feedback plug is rotatable through 240°, allowing the cable exit to be oriented after installation, which simplifies routing in tight spaces. Position data reaches the drive over a Hiperface serial interface; this protocol transmits both absolute position and motor parameters through a single cable. Inside the encoder, an optical scanning head reads a glass scale that contains 128 signal periods, providing fine incremental interpolation for smooth velocity control at low speeds.
The motor has a 040 frame size and a 0450 winding. This combination sets the torque constant, rated speed, and phase current so the drive can be matched correctly. Multi-turn feedback is available because the encoder is multi-turn absolute, storing the shaft angle for several revolutions without external batteries so position data is retained after power loss. The shaft is plain, and the motor is supplied without a holding brake, which reduces inertia and suits applications where static load can be supported by the drive or by external clamps. The C-length stator gives the motor a longer active section within its compact housing.
