SF-B4.0230.030-00.030

The Bosch Rexroth Indramat SF-B4.0230.030-00.030 from the SF Servo Motors series is a permanently excited motor with electronic commutation designed for high-precision automation tasks. It features an integrated STG/MTG encoder delivering single-turn absolute position feedback and a locked rotor current of 22 A for robust start-up torque. The motor reaches a rated speed of 3000 min⁻¹ on a DC voltage of 670 V, and its shaft option—shaft with keyway and feather key, without mating connector ensures secure coupling in diverse drive configurations. Compact dimensions and advanced electronics make this unit ideal for space-constrained control cabinets.

Built to operate seamlessly with the fully digital Servodyn-D inverter system, the SF-B4.0230.030-00.030 offers automatic optimisation via its electronic rating plate. Natural convection cooling is standard, with forced-air cooling available as an option to maintain thermal stability during peak loads. The housing meets IP67 protection grading (excluding output side) for reliable performance in washdown and dust-laden environments. Conformance to DIN 40050/40053 EN 60 445 protection standards further underscores its suitability for demanding industrial applications.

Mechanically, the motor’s maximum length of 341 mm and overall mass of 25 kg balance rigidity with ease of installation. The output flange complies with IEC 72-2 / DIN 42 948 dimensional standards and the ball bearing on the output side is rated for a minimum service life of 20 000 hours. The shaft itself measures 24 mm in diameter with a 50 mm length, providing ample engagement for precision couplings. These features combine to deliver a dependable, high-torque servo solution for packaging, robotics, and CNC machinery.
