Product Description
SF-A4.0125.030-10.050 is a part of the SF series of excited servo motors manufactured by the Rexroth Bosch company. The servomotor is a brushless type and it has an IM B5 type construction. The sinusoidal e.m.f is one of the special features of the unit. It comes with an absolute encoder STG. The size 4 equipment has a locked rotor torque of 0125, which is consistent with technical data. It has a basic smooth shaft without a mating connector. The shaft end is located on the output side. This is crucial for high demands on torque transmission.
Moreover, radiation and natural convection are relied upon for cooling the unit. However, the surface ventilation and forced air-cooling options could also be used to achieve effective cooling of the motor. There are installation pockets over the entire length of the motor. Additionally, it has an electronic rating plate. The flange is in accordance with IEC 72-2 / DIN 42948. The SF-A4.0125.030-10.050 comes with a plug-in connector for output encoder and has balance quality 'N'. It has the IP 67 protection type in accordance with DIN 40050/40053 EN 60 445 and a speed suffix 0.30 which is 3000min-¹. It contains ball bearings located on the output side, having a minimum service life of 20,000 hours.
The product is in the insulation class F in accordance with VDE 0530. To achieve thermal motor protection, the windings have thermistors integrated therein and the temperature range is from ±5C to +155C. There is also a second nameplate attached to the machine on which the identification, inspection sheet, Manufacturer's declaration, warnings and other important points have been noted.
