Gearless motorized roller with variable frequency controller |
摘要 |
A drive roller for a conveyor is rotated by a brushless D.C. motor without any intervening gear reducer. The drove roller has a laminated metal stator with at least three windings external to the stator core. The stator is fixed to a rigid axially extending shaft which supports a roller tube and a permanent magnet rotor on bearings. The rotor is fixed to the roller tube and closely spaced from the stator. A variable frequency power supply controls the induced magnetic field in the stator to control the rotational speed of the drive roller.
