SF-B4.0172.030-14.030

Product Description

The SF-B4.0172.030-14.030 is a component of Rexroth Indramat and falls under SF series motors. It is a popular servo motor type in this series. The locked rotor torque of 18 Nm and locked motor current at M₀ for this servo motor version is 13 A. A 3000 min^-1 rated speed can also be generated with this Rexroth product. The moment of inertia, incl. The encoder for this SF series part number is 40 10^-4 kgm². The torque constant this motor series of Rexroth generates is 1.38 Nm/A. It has a flange of 142 mm in dimension with a shaft of ∅24 x 50 mm.

The maximum length w/o holding brake is 309 mm in this motor version. However, the usual mass without holding the brake for this motor is 19 kg. Also, an STG i.e. single-turn absolute value encoder is the best option available for this SF series motor type. An 18 (120 °C) Nm of transferable holding torque is also a usable value for such type of motor versions. The Single-turn or option Multi-turn motor encoder with the precision or resolution of +/-20 angular seconds/8 million incr./rev is also available in this servo part number.

The SF-B4.0172.030-14.030 part number is comprised of temperature control sensors having two NTC thermistors. Such temperature sensors are extremely sensitive and can easily detect any temperature changes or variations that may occur in this motor. A possible supply voltage for this version of Rexroth servo product is 24 +/-10 % residual ripple 5 % V. For B4 motor types having a holding brake, a rated current of 0.7 A can be practically created without any inconvenience. The protection class of IP 67 is available for this motor version.
