motor DC with encoder : is driver needed?

Hello,

I am always use dc motor or stepper motor so -> I use a driver.

But if I use a DC gearmotor with an encoder the driver (H-bridge) is useless.

Am I right?
Thanks

Every motor needs a driver between it and the Arduino. Some motors (servos are the obvious example) have the driver included in the package.

If your motor does not have its own driver then you will need to get one. A H-bridge is the usual driver if one requires bi-directional control of a DC motor.

thanks,

A standard dc motor have 2 pin for Voltage and GRND,
It is the driver that controle speed and direction

A dc motor with encoder have 6 pin

  • M1 motor(+) 12v
  • GND encoder (-) 5v/3.3v
  • Encoder A phase
  • Encoder B phase
  • Encoder (+) 5v/3.3v
  • M2 motor (-) 12v

So simple and "stupid" question do I need a driver.
I guess not.

Thanks.

I guess not.

If you can figure out a way to control the 12V without one, that would be interesting to see.

I Will do it when my motor arrived (there are in transit :-))

The simple response is already in Reply #1

Of course you need a driver.
