Product Description:
The SF-A3.0068.030-04.015 is a responsive direct-drive motor that is designed for continuous-duty motion regulation applications. It comes in a brushless design with sinusoidal e.m.f., ensuring stable and efficient motion control across demanding cycles. The motor’s direct-drive design enables direct torque delivery to the load without the use of gears or belts, allowing for a more immediate and precise response to control inputs. Its brushless construction enhances durability, eliminating common maintenance concerns. The motor is engineered to generate a sinusoidal electromotive force, producing low torque ripple and minimal vibration. This contributes to quieter performance and helps maintain consistent motion in applications that demand high precision and repeatability.
The SF-A3.0068.030-04.015 offers a locked-rotor torque of 6.8 Nm, ensures stable and secure positioning during startup or when the motor needs to maintain position under load without movement. The motor’s rated operating speed under standard load and voltage conditions is 3000 min⁻¹. This makes it compatible with dynamic servo applications where rapid response and repeatability are essential. The motor is equipped for braking safety with a holding brake that ensures that the motor’s shaft maintains its position when power is removed or during system shutdown. This brake activates automatically when the motor is de-energized, preventing unintentional movement such as drift or free-fall.
The SF-A3.0068.030-04.015 has a mass of 9.0 kg without the holding brake, making it easy to handle during installation and setup. It features an IM B5 type of construction, providing a circular flange on the drive end for mounting. This helps to simplify motor alignment and reduces installation footprint in both horizontal and vertical mounting orientations.
