Product Description

The SF-B4.0230.030-10.030 servo-motor manufactured by Bosch is a permanently excited motor with an electronic commutation. The motor is used in conjunction with a digital servodyn-D inverter system. The speed and position control on this motor is ensured by a single-turn absolute value encoder system (STG) whereas a multi-turn absolute value encoder system (MTG) is only used optionally. The motor features a sinusoidal e.m.f, smooth and low contamination aluminum frame, an integrated resolver, plug-in connection for output and encoder, IP67 protection, and a natural convection cooling.

The nomenclature of the SF-B4.0230.030-10.030 can be broken down into useful information. To begin with, SF shows that the brushless servo-motor with sinusoidal e.m.f comes with a absolute value encoder STG/MTG. B is a design suffix whereas 4 is the size. 0230 depicts the locked torque according to the specific technical data of the motor. 030 means that the motor’s speed is around 3000 min^-1.10 confirms that the servo motor is a basic version and features a smooth shaft without mating connector. The other 030 specifies its version. The smooth output shaft side is required for high demands on torque transmission and special balance quality.

The motor features a ball bearing in its output side with a service life of 20,000 hours minimum. The SF-B4.0230.030-10.030 may experience temperature of over 100 ⁰C which requires a radiation or natural convection mechanism and a touch guard. The insulation class of the motor is F in accordance with the VDE 0530 standard and it can safely operate between 0 ⁰C  to +40 ⁰C. The optional holding brake featured in the servo-motor is a permanent magnet brake that is free from any backlash.
