I calculated the PWM frequency of my brushless motor using this equation : PWM= [Kv*V*poles]/20 and i found 10Khz . As i know that there is a rule which say that the PWM frequency should be at least 10 times that of maximum frequency of the motor. doeas this mean that i have to choose an...
hello!
i was calculating the bootsrap capacitance value of a mosfet driver IR2101 and i was wondering what the operation frequency f means ???
I couldn't find it in the datasheet of the IRF2101 .. well i'm using a mosfet IRF7739l too. can someone help me please in order to calculate the Cboot...
Hello, i'm going to sesign a 3ph H-bridge to control a brushless motor and i'm wondering how can i choose the right mosfets in order to control my motor.
The moter that i'm using is a Turnigy L5055C-700 Brushless Outrunner 700kv having the following caracteristics:
Kv: 700rpm/V
Voltage...
