Product Description:
The SF-A4.0230.030-00.023 is a Brushless servomotor from the SF-A4 series. The servo motor is manufactured by Bosch Rexroth Indramat and it includes an integrated brake system that is designed to maintain torque applications. The motor is designed to provide precise motion control in situations where positioning accuracy and stopping security are necessary. Its design enables flexible installation in systems that are space-constrained.
The SF-A4.0230.030-00.023 servomotor's locked-rotor torque is 18 Nm, and it consumes 14 A of current simultaneously. The shaft, which has a diameter of 24 mm and a length of 50 mm, presents a square 142 mm flange contact. The holding brake provides a torque of 18 Nm at an ambient temperature of 120 degrees Celsius. The motor is 19 kilograms in weight and has a length of 309 millimeters. A power supply fluctuation of up to 5% is permissible during brake action. It is designed so that servo motors can keep working even when the temperature outside is 40 degrees Celsius. The power will drop to 95% at 45 degrees Celsius and 80% at 60 degrees Celsius if the temperature is higher than this. The motor will need to be derated.
The SF-A4.0230.030-00.023 servo motor is compatible with both vertical and horizontal mounting configurations. The integrated brake ensures fail-safe position holding, while the brushless construction eliminates brush fatigue. The servo motor maintains a torque constant of 1.57 Nm/A when operating at velocities of up to 3000 revolutions per minute. The brake necessitates 24 V DC power with a tolerance of ±10% and has a maximum current consumption of 0.7 A. The motor's standardized flange and shaft dimensions facilitate easy mechanical integration. The electromechanical brake guarantees dependable halting without the need for external components.
Frequently Asked Questions about SF-A4.0230.030-00.023:
Q: Why does SF-A4.0230.030-00.023 use 14 A current?
