Use a simple op-amp comparator as the first stage to trigger a relay.

you need OP AMP

Step 1:
Convert 0.5v to 12v
Use opamp or a comparator in comparator mode


Step2:
Amplify current of 12v to a level enough for driving your motor directly (or to a level large enough to drive a relay which then can be used to switch the motor)

adoo thankz bn

Is it a pwm or just a constant dc signal?

constant

constant

since it is lower than 0.7V opto to transistor to mosfet to motor, depending on the motor current draw
