Product Description

The SF-A3.0042.030-14.037 is a motor specially designed for the ServoDyn-D inverter series by Bosch Rexroth. These motors are manufactured and sold worldwide with cutting-edge technology, solving complex engineering problems. The company records a large pool of satisfied customers with its product reliability and cost-efficiency.

The SF-A3 servo motor features electronic commutation and operates with sinusoidal e.m.f. technology. The motor enclosed in a smooth, low-contamination aluminum frame offers installation pockets over the entire length. It is designed to meet IP 67 degree of protection except for the output side. The servo motor comes with permanent magnets and rotates at 3,000 revolutions per minute as its rated speed. The locked rotor torque is measured to be 3.7 Nm with 2.3 A current consumption. In this condition, the torque constant is measured to be 1.6 Nm/A with an ambient temperature of 40 degree Celsius. This permanent magnet motor records 7x10^-4 kgm² moment of inertia. The motor can be mounted using its 116mm SW flange. The output is delivered using a 19mm OD shaft with a 40mm length. This model comes with 223mm of maximum length without the holding brakes and a total mass of 7.0 kg. A single-turn optical encoder is included in its design that operates to monitor the output shaft position.

The SF-A3 permanent magnet motor by Bosch is rated for installation at a maximum height of 1000 MSL. The noise behavior of this model is recorded at 58 dB (A) as heard from a 1-meter distance according to IAW EN 60034-T9. The motor falls in insulation class F specifications and meets VDE 0530. The motor can be used in applications that experience shocks with no more than 6 g value as per IAW DIN IEC 68-2-27.
