Product Description:
Bosch Rexroth Indramat manufactured the Brushless servomotor SF-A4.0172.030-14.151. This motor combines dynamic performance with the ability to retain position, making it ideal for use in precise motion systems. Its design eliminates brush maintenance and produces consistent torque regardless of location.
The servo motor's moment of inertia of 40×10⁻⁴ kg·m² corresponds to a torque constant of 1.37 Nm/A. A high-resolution encoder gives position feedback, allowing the maximum working speed to be 3000 rpm. With a current draw of 10.6 A, this SF-A4.0172.030-14.151 brushless servomotor generates 14.5 Nm of torque when at stall. It is possible to select either a single-turn or a multi-turn encoder, depending on the requirements of the application. When the power is turned off, the holding brake engages automatically to keep the shaft in position. The compatibility of digital feedback makes it easy to integrate digital control systems into modern control systems. Additionally, the built-in brake system ensures that the position will remain secured even in the event that the power suddenly stops working. This servo motor has an electromechanical holding brake that is designed to be activated in the event of a power failure.
The SF-A4.0172.030-14.151 motor uses brushless technology, which requires less maintenance than older designs. Its retaining brake keeps it stable without draining the battery. It is possible for the encoder options of the motor to track positions for one or several spins, depending on the application. The encoder achieves ±20 arc-second precision with 8 million position increments per shaft revolution. This servo motor works well with modern motion controllers and is compatible with digital feedback systems. Accurate positioning is possible with automated systems because they can measure angles well and create a constant amount of torque.
