Asynchronous motor with outer rotor AV 131-2

The AV 131-2 special asynchronous motor with the outer rotor is intended for driving transmissing gears, e.g. abrasive bands used in the furniture industry, alternatively about fabricationpaper at paper industry.

DESCRIPTION

The motors are noted for the stator which is fastened on the shaft. The outlet wires of the stator winding are tapped trough an opening in the shaft to a terminal board being located at the end of the shafts. After connecting to the mains the outer rotor starts to rotate, while its aluminium shell of a barrel shape transmits the torque to  transmissing gear. The outer shape of the rotor as well as the shaft, end tolerances can be modified according to tfe customer's requirements.
