Product Description:
The MSK101C-0450-NN-S1-AP0-NNNN synchronous servomotor belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. Designed as a compact drive element, it translates servo amplifier commands into controlled mechanical power. Within automated cells, the unit supplies precise torque and speed to rotary axes, making it suitable for indexing tables, gantry positioning, and other closed-loop motion tasks where quick response and repeatable accuracy are required. Its synchronous design supports stable motion control in applications that demand accurate positioning, smooth acceleration, and dependable speed regulation across repetitive cycles.
Cooling is handled by natural convection, so heat is released through the housing without external fans or liquid circuits. The housing carries a rating of IP65, blocking dust ingress and guarding the windings against water jets encountered during washdown procedures. Stable operation is specified between 0–40 °C, allowing installation in controlled indoor environments. The insulation system is classified as 155, which corresponds to F-class materials that tolerate elevated winding temperatures before degradation. Power and brake conductors exit on the A-side, simplifying cable routing when the motor is mounted with its shaft directed toward the workpiece. With motor size 101 and length code C, the frame provides the magnetic volume needed for the 0450 winding while remaining compatible with common mounting arrangements for this housing class.
Feedback is supplied through a Hiperface optical encoder that communicates absolute position data to the drive controller. The sensor delivers 128 signal periods per mechanical revolution, and because it is a single-turn device, the absolute value resets after one full rotation, which is suitable for most rotary axes referenced at startup. Mechanical power is transferred through a shaft with a keyway, giving a positive torsional interface to pulleys or couplings. The winding code 0450 matches the drive current profile, and the motor is delivered without a holding brake, so external means must secure static loads when power is removed. This arrangement suits axes that rely on drive-controlled stopping or separate holding hardware rather than an integrated brake.
