Product Description

The SF-A3.0068.030-00.000 from Indramat Rexroth is part of the SF series. Semiconductor switches are used in brushless motors to regulate the on and off duration of the stator windings. The current must be injected into the various coils in a precise order to maintain the continuous motion of the rotor and magnet along the circle. The speed of the electric motor depends on the frequency of the current. A commutator regulates the electronic commutation method by transferring current from one winding to another, which causes the rotor to rotate.

This SF series motor has an A3 dimension, 6.8 locked rotor torque, 3000 per minute rotor speed, a feather key, and a keyway without any mating connector. The motor's version is basic because it is made up of a few simple parts. The shaft is adjusted following DIN 6885 guidelines with a keyway and a feather key to transmit positive drive torque. This positive drive torque maintains a constant velocity ratio throughout the operation. These drives don't have any polygonal effect, slippage, creep, leakage, etc.

The motor of size A3 can withstand the axial force (tensile or compressive) of 133 N. If the motor is not electrically connected and the rotor is rotating, the power connection carries a dangerously high voltage due to its permanent magnet excitation. The mating connectors that are used to assemble the cables should be of 0.5 mm² cross-section and 5.5 to 12 mm in diameter. Brushless motors offer several advantages, including high reliability, reduced noise, improved efficiency, and a longer lifetime. The company offers a one-year warranty for the SF-A3.0068.030-00.000 motor.
