Product Description:
The SF-A3.0093.060-04.050 Servo Motor is engineered by Bosch Rexroth for efficient and accurate motion control in industrial automation environments. It combines robust torque performance with precise position feedback. The motor features a 116 mm flange and operates with high mechanical reliability and thermal stability.
This SF-A3.0093.060-04.050 servo motor provides a locked rotor torque of 9.1 Nm that ensures strong holding and starting capabilities. The shaft dimensions are 19 x 40 mm that offers a secure mechanical interface. Its maximum length without the holding brake is 287 mm that enables compact installation. The motor includes a resolver encoder that supports high resolution feedback. This allows for accurate positioning under dynamic conditions. The precision level of the encoder is defined by an angular accuracy of ~ 20 arcseconds with a resolution of 8 million increments per revolution. The thermal protection of the motor is ensured by thermistors integrated directly into the stator windings. These thermistors are evaluated by the connected servo module that offers real time motor temperature monitoring and protection. The cooling system of the motor relies on natural convection and surface radiation. It is suitable for environments where active cooling is not available. The motor surface can reach temperatures of approximately + 100 degrees C during operation.
The holding brake in this SF-A3.0093.060-04.050 servo motor features a transferable holding torque of 10 Nm at + 120 degrees C. The brake operates on a 24 V DC supply with ~ 10 % tolerance and 5 % residual ripple. The brake's rated current is 0.66 A and it adds 0.6 kg to the total mass. The moment of inertia for the brake is 1.06 x 10-6 kgxm^2. This setup ensures safe holding during power loss or shutdown situations.
