Hi All,
I want to modify my builtin handsfree HP iPaq 6828rw. The built in handsfree, that I get from original package when I buy this PDA, have stereo ear plugs that as I feel it not so good. Because this, I want to change ear plugs with sparated earphone attachable without lose its function to...
blower speed controller
Thanks, I plan to implement your suggestions this weekend. I hope this is final solving for my problem to control my motor-blower's speed. If don't, I need your help again.
Thanks in advance.
matched pair transistors for motor drive
Okay, if I use two transistor MJ15004 and more bigger heatsink applied : Is this enough to control motor current safely about 14 to 16 Amperes without damaged transistor ?
According to MJ15004 transistor datasheet, the collector current maximum upto 20A...
motor speed controller plans
Hi,
I have search to buy transistor Motorola MJ11015 and I don't found it. Can I use two transistor MJ15004 in peugeot 505 blower circuit that you have attached last time (file "P505 blower.jpg" picture) ?
MJ15004 have collector current maximum 20A, and if I use two...
mj15003 speed controller
I have bought my car from secondhand car with blower control unfunction.
I must turn full blower knob to run motor blower and motor blower startly just to highest speed. I can not control motor speed.
When I check it, I don't found circuit control, I don't found...
mj11015 motor
Wow, you really very goodman ossama22, thanks for your responses,very helpful to me.
I see your attached picture, there are two transistor MJ11015 at heatsink but in both circuit diagram (peugeot 505 and 405 circuit diagrams) just one transistor there are used. How are two...
pnp speed control
I am very glad finaly get a respons from you, thank you very much.
Actualy, I want to control motor blower speed for my peugeot 405SR car too (I attached the peugeot 405SR blower control from Haynes manual book).
My question about my circuit are : how much resistance R1 and...

Hi All,
I want to control my DC motor blower speed. The motor blower have 15 amperes current maximum in high speed at about 12.5 Vdc from lead acid battery voltage.
I found from internet a darlington circuit configuration for motor speed control using Q1 BFY51 (NPN)...
motorola 2n3055 vs. digi key 2n3055
Finaly I have found and bought transistor MJ15004.
Now, reference to circuit diagram attached I want to use MJ15004 to control current to drive blower motor speed. In maximum speed blower motor (M) needs current about 14 Amperes at 12 VDC (lead acid...
2n2955 replacement
In my country easy to find transistor made by National Semiconductor with their 2N serial transistors. Which 2N serial transistor is semilarity and able to replace Motorola MJ 15004 ?
motorola transistor cross reference
It is not your false, I am wrong to post question : replacement with complimentary. I am sorry for that.
Okay, Is MJ 15004 easy to find ? If I can't find it, what replacement transistor can I use for similiarity that easy to find in the general electronic...
15003 transistor
Sorry I mean replacement not complimentary. I have edited my question.
I know MJ 15004 is PNP transistor and its complimentary MJ 15003 as NPN transistor.
