Le moteur asynchrone 2 vitesses (Dahlander)
Some smaller induction motors are connected so that all the poles are identical, causing the motor to act as though there is an equal number of opposite poles in between. A Dahlander motor achieves different speeds by switching the configuration of the electrical windings, indirectly adding or removing poles and thus varying the rotor speed. The poles can be varied at a ratio of and thus the speed can be varied at This is because most of the power is used to drive the motor and no electrical pulse switching is done. The system is much simpler and easier to use compared to other speed control methods available. However, the Dahlander motor has the disadvantage of fast mechanical wear and tear due to changing speeds in such a drastic ratio; this type of connection also produces high harmonic distortion during the shifting of poles as the angular distance between the power generated increases as the poles are decreased in the motor. Some typical applications are:   Pumps , wherein two speeds can be used to control the output flow Fans , to get variable air flow output Milling applications Cranes , where two speeds can be used in hoisting applications: one speed for material movement and the other for positioning the material held in the hoist.
