Synchronous Speed When Alternating current (AC) is applied to the stator of a three phase motor, a rotating magnetic field is setup. This rotating magnetic field moves with a speed called synchronous speed. The Synchronous speed can be calculated as follows: 120 times the frequency (F), divided by the number of poles (P): The synchronous speed decreases as the number of poles increases. The table below shows the synchronous speed associated with various numbers of poles at supply frequencies of 50Hz and 60Hz: Rated Speed. The speed of operation of an AC motor when fully loaded at rated voltage is called the rated speed.
1 Stride Frequency â The top row is stride frequency measured in foot contacts per second. 2  The table includes stride frequencies from 3.90 to 5.30 foot contacts per second. 3  Velocity â The left column is velocity measured in meters per second. 4  The table includes velocities from 7.50 to 12.50 m/s. sprinters velocity is determined by stride length and stride frequency. A sprinter can increase velocity by increasing their stride length, increasing their stride frequency, or both. The relationship among these three performance metrics can be expressed by the equation: Equation 1: V = SL * SF.
