Product Description:
The SF-A4.0230.030-00.030 is a Brushless servomotor with an integrated holding brake. It was made with an absolute encoder system to ensure precise placement. The motor's short 309mm length (not including the brake) and conventional mechanical connectors make it easy to incorporate into existing systems. Maintaining constant performance in automated processes while prioritizing dependable operation under variable heat conditions is its design priority.
The SF-A4.0230.030-00.030 servo motor has a torque constant of 1.57 Nm/A at its rated 14A current with the rotor engaged. For accurate positioning, the absolute encoder offers 8 million steps per revolution with a precision of ±20 angular seconds. The flange width of the motor is 142mm, which allows for secure mounting, and the shaft is Ø24mm × 50mm, which allows for direct coupling. Regardless of the operational temperature range, thermal management keeps the braking performance steady. Commutator wear is no longer an issue because of the brushless design. Due to an efficient winding design, electrical characteristics don't change much even when temperatures rise and fall. Mechanical integration with different industrial automation components is made easier using standardized interfaces.
The SF-A4.0230.030-00.030 servo motor has an inbuilt brake system that allows it to work in direct drive applications without the need for extra holding devices. At a temperature of 120°C, the holding brake can retain a torque of 18Nm while functioning within a power supply tolerance of ±5%. Closed-loop control with remarkable repeatability is made possible by high-resolution encoder feedback. It has 30 × 10⁻⁴ kgm² of inertia in its blades and an extra 3.1 × 10⁵ kgm² from the brake that is built in. Even when working at higher temperatures, holding torque is consistently preserved. This motor is ideal for demanding motion control applications due to its combination of accuracy in positioning and rapid dynamic response.
