The circuit is designed to run on 120V so a 120V to 12V transformer will work. The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions. The obvious approaches to varying DC motor speed are varying the supply voltage and varying a resistor in series with the motor (which amounts to the same thing). The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. Traditionally, dc motors have been used in precise speed control applications because of their ability to provide acceleration and deceleration from a dead stop position to full speed fairly easily. stator side and rotor side.
