Product Description

Bosch, Rexroth develops robust and highly dependable industrial drives. SF servo motor drive is one of its product which uses permanent excitation and electronic commutation for its operation. It is brushless technology which requires zero maintenance for longer periods. It is commissioned combined with completely digital Servodyn – D inverter system. Moreover, it uses sinusoidal e.m.f with absolute encoder system. The encoder is typically Single Turn (STG) with optional Multi-Turns (MTG). The SF motor drives come with compact design with working ability of a link voltage of 670 Volts. Wake Industrial sells these highly reliable products worldwide. 

The SF-A4.0091.030-10.015 is the part number of the SF motor drives series. The SF in the part number represents brushless servo motor with sinusoidal e.m.f and an absolute value encoder. The 0091 is the locked-rotor torque which is 10 Nm in accordance with technical stats. The 030 in the part number is the specified rated speed in revolutions per minute which is equal to 3000 rpm. Moreover, these come with a number of options with different characteristics features. The 10 in the part number is depicting the basic version which contains smooth shaft and is not with matting connector. 

The moment of inertia along with encoder is 0.0021 Kilogram Square Meter with a Torque Constant of 1.42 Nm/A. The net weight of the motor drive is 13 Kilogram. The design is suited with the international protection standards of IP-67. This quiet high standard makes this drive suited for operating under strong machine unfriendly environments. The IP-67 does not include the output side. The cooling is done through radiation and natural connection. Temperature sensors in the stators protect it from overheating damages.
