The R911322903 (MSK101D-0450-NN-S2-BP2-RNNN) is an IndraDyn S synchronous servomotor designed for industrial automation. It has a 101 mm frame size, length D, and features natural convection cooling. The motor winding code is 0450, providing a continuous current of 50.6 A and continuous torque of 57.0 Nm at standstill (100 K), with maximum values of 187.7 A current and 160.0 Nm torque. The motor incorporates a shaft with keyway, a sealing ring, and supports high radial loads. The holding brake, with 70 Nm torque, is electrically released. An optical, singleturn EnDat2.1 encoder (2048 signal periods) provides position feedback. The motor is IP65 rated and includes increased concentricity in its design.

Frequently Asked Questions

How does natural convection cooling impact the motor’s operational reliability?

The cooling system maintains temperature stability without external fans. The design minimizes maintenance needs and extends operational life in clean industrial environments.

Why is an optical singleturn encoder advantageous for precision control systems?

The encoder offers direct rotor position feedback with minimal latency. The feedback ensures synchronized performance in high-speed motion sequences.

How does the keyed shaft design improve torque transmission?

The keyed shaft prevents slippage between the motor and mechanical coupling. The design ensures accurate torque transfer during start-stop and load variation conditions.

What role does the 70 Nm holding brake play in operational safety?

The brake holds the load securely when power is removed. The feature enhances stability in vertical or suspended load applications.

How does increased concentricity contribute to motor performance?

The balanced design reduces vibration and mechanical noise. The precision alignment improves bearing life and motion consistency in high-accuracy setups.
