Product Description

The SF-A5.0460.020-04.000 is a type of SR/SF AC servo motor that is used together with the fully digital Servodyn-D inverter system. The motors work with a sinusoidal e.m.f. and differ by their integrated encoders. Their special features include sinusoidal e.m.f, smooth, low-contamination aluminum frame, installation pockets over the entire length of the motors, electronic rating plate for automatic optimization of the Servodyn-D inverter to the motor, holding brake (optional), protection type IP 67 (except output side), cooling by natural convection, and optional forced-air cooling.

The SF-A5.0460.020-04.000 is a 2000 rpm rated machine that has shaft with keyway and feather key, without mating connector and have holding brake. It has a locked rotor torque and current of 46 Nm, and 21 A respectively. The locked rotor values are tested out at 200 rpm and delta winding over a temperature of 100K. The transferable holding torque is 56 Nm at 120 degrees centigrade. The supply voltage to operate the holding brake is 24 volts and the rated current is 1.33 Amperes. The mass of the holding brake is 3.8 kg whereas the weight of the motor without the holding brake is 35 kg. So, the total mass of the machine SF-A5.0460.020-04.000 is 38.8 kg.

The SF-A5.0460.020-04.000 has the basic type of construction IM B5 in accordance with DIN IEC 34-7. It may also be used as IM V1 and IM V3. The ball bearings are located on the output side (flange side) and have a minimum service life of 2.28 years (20,000 hrs). The noise behavior of SF-A5.0460.020-04.000 is a maximum of 58 dB(A) at a distance of 1.0 m as per IAW EN 60034-T9. It has a flange dimension of 190 mm rectangular dia, and the shaft has 32 mm dia with 58 mm length.
