Why armature slots are skewed

A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists ... a two-phase stator winding and a solid copper cylindrical armature in 1885. ... The rotor has a larger number of slots than the stator and must be a ... The conductors are often skewed slightly along the length of the rotor to ...

Not the conductors but the rotor bars are skewed in Induction Motor. This is done to prevent Cogging. Cogging is magnetic locking .When an induction motor refuses to start even if full voltage is applied to it, this is called as cogging. This happ... Skewed motor - Motors & Motor Building - Slotblog Skewed motor - posted in Motors & Motor Building: This is an interesting way of skewing a motor. The magnet plates are skewed instead of the armature. Unused in Box Original Early 1960s Tradeship Inc. Micro Motor MK-70 12V Advantage of Skewed Stator Slots in the Rotor of Induction ... Advantage of Skewed Stator Slots in the Rotor of Induction Motors? In the Induction motor design, the rotor slots are purposely made with a slight skew arrangement. Construction of squirrel cage ... @electronics: Why armature teeth of DC machine is skewed The air gap length changes between the slot and teeth of the armature when the armature is rotating under constant magnetic field. This results in the production of small variation in the torque hence this results can be observed as small vibrations in the frame of the machine. So in order to avoid this vibration effect armature teeth is skewed.
