Product Description:
SF-B4.0125.060-14.050 is a servo motor that belongs to the SF series of motors built and produced by Bosch. These servo motors are unique in their abilities and are robust enough to withstand testing environmental conditions. The motors are versatile and do not use a resolve to control their speed and position; they instead rely on a single turn value encoder. The motor cools itself using radiation and natural convection that helps maintain an ambient temperature during its operation. More importantly, Bosch provides thermal motor protection by integrating thermistors in the motor windings.
The motor is built to last and hence comes with ball bearings that have a minimum service life of 20000 hours, and the flange is put in place in accordance with IEC 72-2/DIN 42 948. For this particular part, the mass of the motor was calculated to be 16 kilograms. However, you should bear in mind that the motor’s mass is measured without the holding brake. Furthermore, the length of the motor is measured as 277 mm, the flange is calculated to be 142 mm, and the dimension of the shaft is 24x50 millimeters. The moment of inertia for the motor, including the encoder, is 30 x 10-4 kgm2.
The motor’s torque constant is 0.71 Nm/A, while the locked-rotor current is calculated to be 17A. The motor’s rated speed is 6000 min-1, and the locked-rotor torque for the motor is 12 Nm. The Holding brake for the motor has a mass of 1.04 kilograms, while the moment of inertia for the holding brake is calculated at 3.1 x 10-4 kgm2. The rated current for the holding brake is 0.7A. To connect the encoders with the SF servo motor, you should use Bosch’s cable harnesses with integrated connectors.
