Product Description

SF-A4.0172.030-04.056 is a motor designed, engineered, and constructed by Bosch, Rexroth. This company makes industrial motion parts with high dependability, robustness and durability.. The SF motors work together with completely digitalized Servodyn-D inverter system. It utilizes permanent magnet for excitation and employs electronic commutation.

The SF-A4.0172.030-04.056 comes with single turn absolute value encoder (STG) for the velocity and position controlling. The motor is compactly designed as per the international protection standards. The design is intended for working with direct current link voltage of 670 volts. The maintenance of the part is almost zero as the they are brushless servo with high durability. They have a cool down by the natural convection with an optional forced air-cooling. Furthermore, it is equipped with International Protection IP-67. This standard makes the motor in extreme hard environmental conditions. The temperature switches prevent the part from overload heating.

The SF in the part number describes the construction of the motor as brushless servo motor with sinusoidal electromotive force along with specified mounting of absolute value encoder as STG or MTG. The A is the design suffix with digit 2 showing the frame size of the motor. The frame size measured from center to edge of the frame. The locked rotar torque is 0172 which is M₀=18 Nm.The 030 is the speed suffix with 3000 revolutions per minute. The 04 is the option which has shaft with keyway and feather key. It is without mating connector and is withholding brake. The last 056 is version of the given series.
