Fanuc motors manual

This feature helps businesses keep downtime to a minimum. Our ALPHA i -B Series servo motors deliver ultra-smooth rotation and superior acceleration for compact high-speed and precision machines.

Our D i S-B Series servo motors can either be air-cooled or, for increased performance, oil- or water-cooled. The Linear L i S-B Series servo motors work without force transmission mechanisms to simplify machine design and maintenance and provide massive amounts of thrust force. Unlike conventional drives, these motors work without any force transmission mechanisms, making machine design and maintenance easier no ball screws, no backlash.

The linear design enables rigid long-stroke axes, increased thrust force and multi-head configurations by arranging multiple coil sliders on a single magnet track. A conventional servo motor converts electrical energy into rotational motion. It comprises stator windings and housing, permanent magnet rotor and laminates, pulse coder and end rear bell along with front and rear bearings. The stator windings and housing represent the electromagnetic part of the servo motor. Its C-face mounting secures it to the frame of a machine or load that is to be controlled.

Its ferrous core, made of steel laminates, focuses the magnetic field produced when electrical current flows in the copper winding. For each revolution of output from a servo motor, the 3-phase input power must be cycled four times. The motor rotor is the rotating part of the motor that is usually coupled to a ball screw. It is made of an output shaft that is centered in an iron mass constructed of steel laminates.

The rotor is suspended by a pair of bearings holding the output shaft in the center of the stator. This causes a magnetic field to be generated around the conductor carrying the current. The magnetic field generated by passing current through a conductor will change polarity, depending on the direction of the current flow.

The magnetic field induced by the wire is not enough to cause the second magnet to move. To amplify the magnetic field, the wire is stacked upon itself multiple times. By doing so, the magnetic field is multiplied by the number of wires stacked in the coil. Additionally, the winding is mounted with an iron center, further focusing the generated magnetic field.
