Product Description

SF-A3.0068.060-00.000 is a synchronous motor manufactured by the Rexroth Bosch company as part of the SF series. It has a design suffix A and a frame size of 3. The permanently excited servo motor is made of a smooth low run aluminum frame and an electronic rating plate. It was also constructed with compact design that allows operation with a d.c. link of 670V. It has a locked rotor torque of 0068 and the speed suffix is 060, which is 6000 min. The shaft has a keyway and feather key, but it has no mating connector.

It is a part of the line of SF synchronous motors used in conjunction with the servodyn-D inverter system. It uses thermistors integrated in the windings for thermal motor protection. The temperature range is between 5C and+155C. Cooling occurs by natural convection and optional surface ventilation as well as forced-air cooling. SF-A3.0068.060-00.000 has a noise behaviour of 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.

The functional unit has an encoder valuable for information on commutation, position as well as speed of the motor. The SF motor runs with a single-turn absolute value encoder (STG) and optional a multi-turn absolute value encoder. It has ball bearings located on the flange side with a minimum service life of 20,000 years. The flange is in accordance with IEC 72-2 / DIN 42948. The unit has a balance quality category 'N' and flange precision 'N'. The construction is an IM B5 type and the protection type is IP 67.
