Nettet2. jul. 2024 · RMS, or root mean square, is a statistical term that is used for determining the mean (or average) of a set of values. It’s especially useful when the values vary as a function of time. The technical definition of root mean square is the square root of the mean of all the squares in a sample. For example, to find the root mean square of a set ... Nettet7. okt. 2024 · The speed of the motor is inversely related to the number of poles in the rotor. The relationship is explained by the following formula: Where: Ns = synchronous speed. f = frequency of three-phase power supply. And #p = the number of poles. Alternatively, it can be written as: Where: Ns = synchronous speed.
