Direct On Line Starter | Electrical Notes Articles

Mar 13, 2012· Introduction: Different starting methods are employed for starting induction motors because Induction Motor draws more starting current during starting. To prevent damage to the windings due to the high starting current flow, we employ different types of starters. The simplest form of motor starter for the induction motor is the Direct On Line starter.

How does the number of poles in an induction motor ...

But it's more complex in an induction motor, as torque is also a function of the relative angle between the magnetic flux in the rotor and stator (slippage). There are a number of design parameters that determine the current and the slippage, and the number of poles only affect the torque to the extent that they effect those other parameters.
