The pulse widht will determine the speed a DC motor runs, but what dictates which frequency ?
It is for a 130VDC / 2.75 HP 21 Amperes maximum treadmill DC motor that will operate from a bank of batteries at 72 Volts.
How to calculate the most convenient frequency ; and what undesirable behavior happens when frequency is over/under the optimal ?
