Product Description

The SF servo motor SF-A3.0042.030-10.037 is a product of Rexroth Indramat. It is a brushless motor type that is a part number of the SF series servo motors. This motor contains a size 3 motor frame with a design type A. According to the technical data available for this SF product, one can estimate the locked rotor torque assigned to this motor type. This servo motor has a 0042 element in its part number suggesting that it has 3.7 Nm locked rotor torque. Also, the rated motor speed for this servo motor can be established through 030 elements of this motor. For instance, it has a 3000 min^-1 rated motor speed.

The basic version of the smooth shaft, w/o mating connector, is present in this Rexroth motor series product. The torque constant this motor contains is 1.6 Nm/A with ∅19 x 40 mm shaft dimensions. The locked rotor current at M₀ is 2.3 A and the moment of inertia, including the encoder is 7 10-4 kgm2. Moreover, the mass of this SF-A3.0042.030-10.037 Rexroth servo motor is 7.0 kg without a holding brake.

Like other SF motors, this servo motor is also an IM B5 type of construction with an absolute value encoder having Singleturn. A plug-in connector can be utilized for the encoder and the output or brake. This motor type is comprised of a temperature control system having NTC thermistors that can easily sense any variations in the temperature of the motor. Protection is a crucial aspect of this SF motor series and for this reason, protection class IP 67 is applied to this motor version. A 1-year warranty is provided with this SF series servo motor.
