Product Description

The SF-A3.0093.030-00.018 is a servo motor for the Servodyn-D drive series manufactured by Bosch Rexroth. It is an asynchronous motor belonging to the SF line of motors featuring a single-turn absolute encoder for motor feedback. The unit is a magnet excited motor that employs electronic commutation. It has a motor frame size of 3 and has an output shaft with a keyway. The unit features the IM B5 construction build and has a protection category rating of IP 67, except for the output flange. The unit is intended for operation in ideal environments with ambient temperatures not exceeding 40 degrees Celsius. Also, for optimal performance, it shouldn?t be installed at an elevation that is more than a thousand meters above mean sea level.

The SF-A3.0093.030-00.018 is cooled by radiation and natural convection. It has a locked rotor torque value of 8.1 Nm and a rated speed of 3000 revolutions per minute. The torque constant of the motor is 1.35 Nm/A, while its moment of inertia when the encoder is connected is 16 x 10-4 kgm2. The product has a locked rotor current of 6 amperes. The maximum length of the device without the holding brake is 287 mm, while the dimensions of the shaft are 19 by 40 millimeters. The flange has a length of 116 mm.

The SF-A3.0093.030-00.018 has an encoder with a resolution of 8 million increments per revolution and a precision of about 20 angular seconds. It can be paired with an optional multi-turn encoder. There are thermistors in the windings of the device for thermal protection. The unit uses ball bearings, which are located on its flange side. These bearings are rated to have a minimum service life of 20,000 hours.
