Product Description:
Rexroth Indramat's SF-A4.0091.030-00.030 is a Brushless servomotor. The servo motor is compatible with a variety of mounting angles, allowing for versatile integration, and is specifically designed for precise motion control. The motor runs smoothly thanks to its sinusoidal electromotive force. Its 13 kg weight and small 142 mm flange size make it ideal for automated applications where space is limited.
The shaft diameter of the SF-A4.0091.030-00.030 servo motor is 24 mm, and its length from flange to end is 50 ± 0.5 mm. For exact placement, the SF Encoder offers a high angular precision of ±20 arc seconds. In high-performance applications, its dynamic reactivity is guaranteed by its moment of inertia, which is 30 × 10⁻⁴ kg·m². Because of the sinusoidal back-EMF waveform, a smaller torque ripple results in a greater amount of fluid activity. Achieving a compromise between size and structural rigidity, the motor's length is 246 mm. Because it is brushless, mechanical commutation does not cause wear. The dimensions of the shaft and the flange are standard, which ensures that mechanical integration is simplified.. The drive signals are sinusoidal in order to lessen the amount of vibration and noise that is produced.
Because it may be mounted in multiple orientations, the SF-A4.0091.030-00.030 servo motor allows for flexible installation. The high-accuracy encoder ensures that closed-loop control systems are reliable in their operation. The motor runs at 3000 rpm and draws 7.0 A locked-rotor current. Quick acceleration and deceleration are made possible by the motor's low inertia. Reliability in severe motion control applications is guaranteed by the strong structure. Stable industrial automation operations are made possible by the motor's consistent torque output across its speed range.
Frequently Asked Questions about SF-A4.0091.030-00.030:
Q: Why does SF-A4.0091.030-00.030 use sinusoidal e.m.f?
