Product Description

When it comes to producing high-quality, efficient, and affordable AC servo motors, Rexroth Bosch has a proven track record.The SF/SR motor series are mid-size applications. The SF motor series is a separate motor family that uses either a multiple-turn or singular-turn absolute encoder for motor feedback. Meanwhile, SR motors use relative encoders. Focusing on the SF motor series, a particular motor model that you can purchase is the SF-A4.0172.030-04.050.

The SF-A4.0172.030-04.050 has the capability to maintain continuous operation even in poor environmental conditions. Although this motor model uses natural convection for cooling, the surface temperature of the motor reaches only about 60 degrees Celsius at normal operating conditions. Under normal operating conditions, the motor operates within its favorable ambient temperature and installation level. The working ambient temperature of the SF-A4.0172.030-04.050 is between 0 and 45 degrees, and it directly affects the motor surface temperature during operation. Meanwhile, at installation levels beyond 1 km above measured sea level, the motor has reduced capabilities, also known as de-rating.

The SF-A4.0172.030-04.050 also uses thermal protection for temperatures between -5 and 155 degrees, an insulation class F, and an STG/MTG encoder. Depending on the intended application, the motor supports both foot and flange methods of mounting. Its integrated holding brake can reach a torque of 18 Nm to halt motor operation. Finally, the output parameters of the SF-A4.0172.030-04.050 are 18 Nm at standstill and 3000 rpm at rated conditions.
