Product Description

The SF-B5.0250.030-04.050 is a part of the SF series motor that is developed by the Rexroth Bosch Group. This precision servomotor is designed for applications that require high dynamic performance and accurate positioning. This model features a shaft with a keyway and feather key but it doesn’t come with a mating connector. The motor mass is 24 kg and it has a maximum length of 300 mm without the holding brake. Moreover, this motor shaft measures 32 mm in diameter and 58 mm in length which affirms its suitability for different industrial setups.

This permanently brushless servomotor showcases strong build quality and it has a protection type of IP 67 excluding the output flange side. The locked-rotor torque of this motor is measured at 23 Nm and the motor operates at a rated speed of 3000 min-1. The SF-B5.0250.030-04.050 has an optional feature of a holding brake capable of delivering a holding torque of 56 Nm at 120°C.

The holding brake requires a supply voltage of 24 V ± 10%, with a residual ripple of 5% and it has a rated current of 1.33 A. Additionally, the brake’s moment of inertia is calculated at 30 x 10^-4 kgm² and its weight is measured at 3.8 kg. It’s essential to note that the motor's surface can reach temperatures approximately up to 100° C, so a touch guard must be provided when necessary. Wake Industrial offers this servo motor from the SF series with a one-year warranty and provides damage-free delivery nationwide.
