Hi,

Anyone knows is there a battery powered driver, which has H bridge and can drive two motors at the same time? It's better that two motors can be drived at different status -- speed...

Thanks!

 

I was tempted to write a long rant about the impossibility of ever giving a decent answer to a good percentage of the questions to this board . . . but with my tongue firmly clenched between my teeth.

1.) How much power will the motor need to develop (is this for a bus? a toy car? a camera lens?)

2.) What kind of battery? Voltage? Internal Impedance?

 

Hi Ken,

Sorry I should specify my application at first time. I think this DC brush motor outputs around 40 watts power. It's used for steering a small car. I will use a 24V battery. I'm not sure the internal impedance. I think it'll be a normal one.

Thanks.

 

Hi Ken, sorry I should specify my application at very first. I am using a 24V battery and two 24VDC brushed motors in my application. Each of motor outputs around 40 watts power. I need the drive is bi-directional h bridge and maybe PWM control lines are perfect. Thanks!

 

40 Watts is pretty small compared to what I am accustomed to working with. I have integrated several small micrometer drives using this amplifier.

Is should work well for the voltage and power range (with plenty of margin).

Sounds like an interesting project.

 

The amps for 24V brush motors in velocity mode (with backEMF, taxo or encoder feedback) you may find at Elmo (http://www.elmomc.com), AMC (www.a-m-a.com), Copley ( http://www.copleycontrols.com), etc.
But how you plan to connect both motors?
