Product Description:
The MSK101E-0450-NN-S2-AG2-RNNN is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. It is used in automated machinery that requires closed-loop torque and speed control, including gantry axes, packaging equipment, and metal-cutting spindles. When connected to a compatible drive controller, the motor converts electrical input into precise rotary motion while returning position data for stable regulation. Its servo design is suited to coordinated motion tasks where repeatable positioning and smooth speed changes must be maintained through frequent acceleration and deceleration.
During standard duty, heat is removed through natural convection, so the motor does not require external forced-air devices. An electrically released holding brake provides 70 Nm of torque to keep vertical or indexing axes from drifting when power is removed. Motion feedback is transmitted over EnDat2.1, and the internal optical encoder produces 2048 signal periods per mechanical revolution for fine position resolution after drive interpolation. The output uses a plain shaft, which suits direct coupling arrangements without a keyway. The three-phase power connector is placed on the A-side of the housing to support straightforward cable routing.
The motor uses increased concentricity, which improves running accuracy by reducing radial runout between the rotor and stator. Frame designation 101 sets the flange size and bolt-circle pattern, while motor length code E provides a longer active section for higher continuous torque than shorter versions in the same platform. The winding code 0450 matches the motor’s electrical characteristics to compatible drives, including current and time-constant behavior. The absolute encoder reports position in Singleturn format, so the feedback system tracks one mechanical revolution without multi-turn counting. Because the encoder is absolute within one turn, the drive can determine shaft angle immediately after startup without relying on an incremental reference cycle for that revolution.
