Product Description:
The SF-A4.0230.030-10.021 is a Brushless servomotor that Bosch made for controlling movements with great accuracy in industrial automation. The motor is small, with a flange width of 142 mm, and has standard interfaces that make it easy to add to current systems. It also works reliably in a range of temperature conditions.
The rotor inertia of the SF-A4.0230.030-10.021 servo motor is 30 × 10⁻4 kgm², and the brake inertia is an extra 3.1 × 10⁻4 kgm². The absolute encoder has an accuracy of ±20 angular seconds and 8 million steps per turn, which makes it perfect for closed-loop control. The holding brake has a power source tolerance of ±5% and can handle 18 Nm of torque at 120°C. The motor's 309 mm length (without the brake) and sturdy build make it space-efficient without sacrificing longevity. Its thermal stability lets it work consistently in situations where temperatures change. Standardized mechanical interfaces on the motor make it easier to put in automated systems. It's built-in brake keeps the holding force stable even when the temperature is high. The servo motor has an absolute encoder and a built-in locking brake that make sure it is placed correctly.
The SF-A4.0230.030-10.021 servo motor allows direct coupling, which means that holding mechanisms on the outside are not needed. The high-resolution encoder makes tracking more accurate, and the brushless design makes it easier to keep up. When the rotor is turned on, it draws 14 A and has a torque constant of 1.57 Nm/A. Because it can be controlled precisely, the servo motor can be used for dynamic motion applications. The absolute encoder is responsible for maintaining a consistent position as well as preventing any changes
