Product Description

The SF-A4.0172.060-10.050 model is a product of Bosch Rexroth's advanced servo motors line-up. The motor is a part of the SF-A4 family and comes with the latest encoders providing enhanced operation and accuracy. These motors are available with a variety of winding and technical features to meet your diverse requirements.

The SF-A4 servomotor is rated for 6,000 revolutions per minute. The mating connectors are not included with this basic permanent magnet servo motor. The motor uses 13 A of current to provide 18 Nm of locked rotor torque with no= 200 min-1. With a torque constant of 1.38 Nm/A at ambient temperatures up to +40 degree Celsius, this motor runs smoothly with its top-grade ball bearing. With a minimum service life of up to 20,000 running hours, this bearing emphasizes to its maintenance-free service life. The overall length of the motor is not more than 309mm (excluding holding brakes) with a mass of 19 kg. It comes with a 142mm flange and 24mm x 50mm length cylindrical output shaft. The servo motor is aimed to have a brushless design offering minimum maintenance operating on DC 670 V. With 40x10-4 kgm2 moment of inertia (including encoder), this servomotor makes its way for many modern applications that demand a high degree of reliability.

The SF-A4.0172.060-10.050 model by Rexroth Indramat offers plug-in connectors for the output and encoder. It has an aluminum frame with low-contamination material and installation pockets over the entire length of the motor. This permanently excited synchronous motor operation is based on sinusoidal e.m.f. This motor is intended to be used in conjunction with a fully digital Servodyn-D inverter system. Users don?t need to worry about cooling owing to its naturally aspirated housing design.
