Product Description
The SR/SF motors are prominent due to their characteristics that include sinusoidal e.m.f, integrated encoder (SF) / or integrated resolver (SR), plug-in connection for output and encoder, holding brake (optional), protection type IP 67 (except output side), cooling (natural and forced). The SF-A5.0460.020-00.000 is a brushless servomotor with sinusoidal e.m.f and absolute value encoder STG/MTG. It has a rated speed of 2000 revolutions per minute.
The SF-A5.0460.020-00.000 has the shaft with a keyway and feather key and without the mating connector. For positive-drive torque transmission, the shaft end on the output side has a feather key and feather keyway as per DIN 6885. For normal demands, shaft connections with feather keys, keyed connections, and multiple key connections are suitable. Under load, the shaft-hub connection is subject to a multi-axis stress condition, which results from torsional, radial, and axial forces and the bending moment. In the case of strong reversing operation, the seat of the feather key may wear out, thus causing a change in the running behavior.
The SF-A5.0460.020-00.000 have a total weight of 38.8 kg where the machine weight is 35 kg and holding brake weight is 3.8 kg. It has a locked rotor torque at 200 rpm and delta winding over a temperature of 100K is 46 Nm. The locked rotor current at 200 rpm and delta winding over a temperature of 100K is 21 A. The transferable holding torque in the holding brake section is 56 Nm at 120 C with a 24v supply voltage. The permissible residual ripple of supply voltage is 5%. The precision and resolution of the encoder are 20 angular seconds and 8 million incr./ revolution respectively. The maximum length of the machine without holding the brake is 383 mm.
