How is frequency is efecting when a motor running by electric power,What is the relation of KW with FREQUENCY?
Dear Meetantacheri, I am not sure which frequency you refer to: 1) The Power Supply Frequency You need to look in your Ordinary Level Physics Books or on the wwweb at: Synchronous AC Motors Asynchronous AC Motors 2) The Rotational Speed of the Motor: For a DC Motor this depends on whether the rotor and stator are Series or Parallel Connected and the Mechanical Load that is on the Motor. For a Synchronous AC Motor you get field slippage if the mechanical load is too high I am not sure what you mean by the kW / f part. If a motor is overloaded it slows down, takes a lot of current and the power consumption rises. This overheats the motor and the winding are destroyed. (see back-EMF)
