Product Description

SF-A4.0125.060-00.000 is a permanently excited brushless servo motor manufactured by the Bosch group. This piece comes with a design suffix A and a frame size 4. It has a locked rotor torque of 0125 in accordance with technical data while the speed suffix is 060,which is equivalent to 6000min-?. It is a synchronous motor with a sinusoidal e.m.f and it was designed with electronic commutation. It has a shaft with a keyway and a feather key without a mating connector. The unit possesses ball bearings with a minimum service life of 20,000 years situated on the output side.

The motor is used in conjunction with the digital servodyn-D inverter system and it comes with a single turn absolute value encoder system. The compact design of the permanently excited motor was meant to allow it operate with a d.c. link voltage of 670 V. The value of the noise behavior of the motor is max.58 dB(A) at a distance of 1.0 m, IAW EN60034-T9, while the shock resistance is 6g IAW DIN IEC 68-2-27. SF-A4.0125.060-00.000 has an IM B5 type construction and a balance quality category of 'N'. The protection type is IP 67 and it has a plug-in connection for output and encoder.

The device is ventilated by natural convection, radiation, surface ventilation or optional forced-air cooling. The insulation class of the unit is F in accord with VDE 0530. Additionally, a second nameplate is attached to the machine. This nameplate contains crucial information such as the identification, inspection sheet, manufacturer's declaration, warnings of High voltage and Hot surface. The motor comes with a one year warranty period.
