Product Description

The SF-A4.0125.030-10.011 is a 3000 rpm brushless servomotor with sinusoidal that is used for precise positioning and high-speed applications. It has a shaft with a keyway and feather key, without a mating connector, and it is protected with insulation type IP 67. The LRA for this series of motors is 10.6 A, and the locked-rotor torque at 200 rpm is 14.5 Nm at 200 rpm, and the winding over temperature at 100K. The torque constant is 1.37 Nm/A, and the moment of inertia of this machine including the encoder is 30 x 10-4 kgm2. 

The dimension of the machine consists of flange, shaft, and length sizes. The flange has a dimension of 142 mm diameter whereas the shaft has a diameter of 42 mm, and the length of the shaft is 50mm. The maximum length without the holding brake is 277mm. The mass of the machine without the holding brake is 16 kg. The holding brake weight is 1.04 kg, and the total weight of the machine is 17.04 kg. The precision of the equipment is 20 angular seconds, and the resolution is 8 million increments per revolution.

The transferable holding brake of the SF-A4.0125.030-10.011 is 18 Nm at 120 C. The supply voltage of the holding brake is 24v with a variation acceptance of 10%. The residual ripple is 5% of the supply voltage, and the rated current of the holding brake of this machine is 0.7 A. The moment of the inertia is 3.1 x 10-4 kgm2. It derates over 40 C and above 1000 m m.s.l. The construction is the basic type IM B5 in accordance with DIN IEC 34-7. The minimum service life of the bearing is 20,000 hrs.
