SF-B5.0250.030-00.000

Product Description

The SF-B5.0250.030-00.000 is a servo motor designed and constructed by Rexroth Indramat. This SF series motor type comes with an STG/MTG encoder. This Rexroth SF servo motor is considered a permanently excited motor type that has electronic commutation. It is used with a completely digital Servodyn-D inverter system. This motor product works with a sinusoidal e.m.f. and has its own integrated encoder. Two types of encoders can be used in this SF series model, one is a single-turn absolute value encoder system (STG) and the other is a multi-turn absolute value encoder system (MTG). The later encoder system is an option for this servo motor type. These encoders are used to control the motor speed and motor position in the machine.

The recommended rated speed for this motor system is 3000 min^-1. This SF series model comprises a permanently excited synchronous motor in a specifically compact design required for operation with a DC link voltage of 670 V. It also delivers a locked rotor current of 23 A. The SF-B5.0250.030-00.000 motor type offers various special features. It has a shaft with a feather key and keyway w/o a mating connector. A low-contamination and smooth aluminum frame is also a prominent component in this motor type. Installation pockets are present on the entire length of this motor version.

For automatic optimization of the inverter to this motor, an electronic rating plate is available. Plug-in power connection for its output and encoder connectors will help make it a reliable motor type. The holding brake feature is optional in this motor type. It provides cooling by the natural convection method. However, it also has an optional forced-air cooling system. The protection type for this SF servo motor product is in accordance with IP 67 except for its output side.
