Product Description

SF-A3.0068.030-04.000 is a permanently excited servo motor that works together with the fully digital servodyn-D inverter system. This efficient motor produced by the Bosch group comes with a sinusoid e.m.f. and has a single turn absolute value encoder system. It is part of the SF series, comprising of permanently excited synchronous motors designed to operate with a dc link voltage of 670V. It is a brushless servomotor with a design suffix of A and a frame size of 3. The locked-rotor torque in accordance with technical data is 0063. It has a suffix speed of 030 which is equivalent to 3000min-¹.

The special features of this motor include the sinusoidal e.m.f, the smooth low contamination aluminum frame as well as the integrated encoder. The basic equipments of this motor include the smooth shaft, the electronic rating plate and the temperature control with two NTCs. It has a shaft with keyway and feather key without mating connector and with holding brakes. These are suitable for normal demands. The smooth shaft ends on the output sides are for high demands on torque transmission.

The SF-A3.0068.030-04.000 has a basic type of construction IM B5 which is in accordance with the DIN IEC 34-7. Also, the flange is in accordance with 72-2 / DIN 42 948. It achieves cooling by radiation and natural convection. It also has the surface ventilation option. It comes with an encoder integrated for information on commutation, speed and position. The integrated encoder available for the SF motors are the absolute value encoder single-turn (STG) and the optional absolute value encoder multi-turn (MTG) 4096 rev. absolute. It has a warranty period of one year.
