Product Description:

The SF-A3.0068.030-00.018 belongs to the SF series of servo motors built by Rexroth Bosch for their Servodyn-D series of drives. The permanently magnet-excited motor employs sinusoidal e.m.f. in its operation. The design of the unit is very compact and the unit can be used with a DC link voltage of 670 volts. As part of the SF series of brushless servo motors, the product features a single-turn absolute value encoder system for measuring and controlling the speed and position of the rotor. There are installation Pockets on the smooth aluminum frame of the unit. It features an electronic rating plate and has two NTCs for temperature control purposes.

The SF-A3.0068.030-00.018 has its shaft end on the output side of the unit. The shaft has a feather key and feather key way, which enables positive-drive torque transmission in accordance with the DIN 6885 specifications. This type of shaft connection is ideal for normal demands on torque transmission. The motor does not feature a holding brake. It is rated to have a protection type of IP 67 and uses the IM B5 basic type of construction as per the DIN IEC 34-7 standards. The unit?s noise behavior rating is 58 dB (maximum) at a distance of 1 meter.

The SF-A3.0068.030-00.018 has a mass of 9 kilograms. Its moment of inertia is 11 x 10-4 kgm2 with the encoder attached. Its rated speed is 3000 rpm and its locked-rotor torque is 6.8 Nm. The unit has a maximum length of 255 millimeters. It is cooled by radiation as well as natural convection. Surface ventilation options can be attached, if necessary. A touch guard can be provided since the surface temperatures of the unit can reach up to 100 degrees Celsius.
