Product Description:
For motors, having more windings means higher torque output. In particular, the torque output of a motor depends on the intensity of the magnetic field, which relies on the windings present. However, the drawback of increasing the windings is that the motor becomes bulky and heavy. For the SF motor series, the same concept applies. Compared to other motors from the SF-A4 family line, the SF-A4.0230.030-04.050 offers higher torque output at the cost of bulkier and heavier construction. Weighing about 23.7 kilograms and spanning a length of about 388 mm, this motor model can meet higher demands.
Like most, if not all, SF motors, the SF-A4.0230.030-04.050 uses radiation and convection to lower motor temperature during and after operation. SF motors have an integrated absolute encoder, which may be single-turn (STG) or multi-turn (MTG). At the starting condition, the torque is 22 Nm, while the current is 14 A. During the starting condition, also sometimes referred to as the locked-rotor condition, the rotor does not rotate. The parameters measured during this condition are mainly used for planning the protection devices. For motors, overcurrent protection is of utmost importance since high currents can generate heat in the motor windings and overheat the motor. For the SF-A4.0230.030-04.050, the recommended motor and holding brake cables are 4 x 2.5 square millimeters and 2 x 1.5 square millimeters, respectively.
According to the official documentation, assuming a rated speed of 3000 rpm, the maximum radial force is estimated to be 810 N, while the axial force is fixed at 154 N. The SF-A4.0230.030-04.050 has an integrated holding brake, and its shaft has both a keyway and a feather key.
