i read a specification of a wiper motor and it tells me that its no load current is 2Aand full load current is even larger.is it the current that will flow through the motor when i connect it to a 12V battery?it is too large for the controller.........
Yes, the 2A is the current flowing through the motor. Starting currents (stall current) can be 6-12 times the full-load current (in your case, 12-24A). This starting current only flows for a fraction of a second, though.
if i want to build a H-bridge with transistors such as TIP120 to control the direction of the motor, that means the high current will burn the transistors?how to cope with this situation?
