Product Description
Bosch, Rexroth is a leading manufacturer of industrial automation parts and is widely known for its durability, robustness and reliability of its products. SF motor drive is one of its developed series of products. The SF motor drives are brushless servo motors with sinusoidal e.m.f. The construction of the motors is for permanent excitation. Additionally, it uses electronic commutation principle for its operation. It is with compact designs and highest International Protection standards making them suitable for commissioning at machine unfriendly environments. The design is suitable for its smooth working of 670 volts of linking voltage. Wake Industrial proudly sells these highly dependable products.
The part number SF-A3.0068.030-14.053 has codified all its cardinal features. The SF represents the servo motor with brushless technology which operates with sinusoidal e.m.f. The A and 3 shows design type and frame size of the motor drive respectively. The Locked-Rotor Torque is codified in 0068 which is equivalent to 6.8 Nm as per the technical specifications. The 030 in the part number is for rated speed of the motor from the manufacturer side that is equal to 3000 revolutions per minute. The 14 is option of the motor which is basic version with along with a holding brake and is not equipped with matting connector. The net mass of the motor excluding brake is 9 Kilogram.
The protection from overheating damages is done through fitting the temperature sensors in the stator. The heat is generally dissipated from the motor body through radiations and natural convection. It is different from SR series of motor drives as it employs absolute value encoder for precise speed and position controlling while the SR series uses a resolver for the given purpose.
