Now is to restore a motor driver module, 20 pins, don't know what is the commonly used high power motor driver chip type, hope everybody to give directions,

CodePudding user response:

High-power this range is a little big, should address the specific parameters, such as current, voltage, in addition, the motor is a brush motor, brushless motor or ac motor and so on, to illustrate the
But this parameter 600 KHZ, can choose the range of compression

Brushless dc motor drive module, H bridge has two road PWM chip working frequency up to 600 KHZ input, the duty ratio can be 0-100% chip built-in hardware control dead zone time, able to adapt to frequent commutation motor effectively protect H bridge chip, working frequency up to 600 KHZ, used empty with motor drive,

You take a look at this information can be a better location

600 KHZ frequency is too high, can do the launch pad, but can't drive motor (currently should not yet)

CodePudding user response:

Then can I ask now mainstream chip frequency is how much? I really don't know, seen the highest is about 300 KHZ,

CodePudding user response:

Such as the switching speed of IR2101 for

200 Ton Turn - On the Propagation Delay - 130 ns
Toff Turn - Off the Propagation Delay - 90, 200 ns

Tr Turn - On Rise Time 120 ns - 80
Tf Turn - Off losing Time - 40 70 ns

What do you think of how many frequency is more appropriate?

CodePudding user response:

That is to say, the 600 KHZ is actually a misleading information, actually cannot achieve, it is no use to mean?
