Battery selection to power 4 mini DC motor for smart car

Projects General Guidance

Hi everybody ,

Can i use 4 AA battery connected in to series which provide 6 volt for the 4 mini DC motor?
I dunno how much the current can provide by 4 AA battery , and not sure the battery able to power on the 4 motor simultaneously .

The mini DC motor have following features:

Double axis gear motor
Working voltage: 3V ~ 6V
Unloads current: ≤200mA @ 6V, ≤150mA @ 3V
Unloads speed: 200 ± 10%RPM @ 6V, 90 ± 10%RPM @ 3V

I connected 4 mini motor for my smart car using L293D motor driver with pwm speed control.

And please suggest me the appropriate battery or power i should use.
Thanks

A 6volt battery might not provide 6volt for the motors.
There will be losses in the motor drivers, especially high (~2.5volt) if you're going to use the ancient L293D or L298.

AA is a battery size.
How much current they can provide depends on battery chemistry.
Alkaline (non-rechargeable) or Ni-MH (rechargeable) should be able to provide the current.

Your 4 double-A alkaline batteries should work fine.
