A circuit which allows a connected motor to operate in clockwise and anticlockwise directions through alternate input triggers is called a bidirectional controller circuit. The first design below discusses a Full bridge or H bridge based Bidirectional motor controller circuit using the 4 opamps from the IC LM324.
The Permanent Split Capacitor (PSC) single-phase induction motor is the simplest and most widely used motor of this type. The classification, construction and working principle of single-phase induction motors are explained in detail in the application note “AC Induction Motor Fundamentals” (AN887) available from Microchip.
The value of the capacitor is chosen so that the total impedance on the auxiliary winding produces sufficient phase shift in current to generate a rotating magnetic field in the air gap. Typically, the current flowing through the start winding leads the current flowing through the main winding by 90 degrees.
Voltage: The circuit and motor make use of the common power supply. This implies that because the highest working voltage of the LM324 is 32VDC this likewise becomes the maximum voltage accessible to operate the motor. Current: The IRFZ44 MOSFET is designed for 49A; the IRF4905 will be able to handle 74A.
Resistor R15 and capacitor C2 are a simple low pass filter. This is meant to clean any voltage spikes brought on by the MOSFETs as they turn ON supply power to the motor. Parts List
Typically, the current flowing through the start winding leads the current flowing through the main winding by 90 degrees. By adding a microcontroller-based control circuit to the motor, the voltage across the main winding and start winding can be maintained at 90 degrees to each other.

Film Capacitors – AC Capacitors
The standard bidirectional asynchronous induction motors used in appliances such as washing machines have two windings: main and auxiliary. A run capacitor is needed to start the motor into the required direction by phase shift. Electromechanical switches are used to control it (on-off, direction of rotation).

Run Capacitor Selection Guide
Start vs. Run Capacitors. Start capacitors give a large capacitance value necessary for motor starting for a very short (seconds long) period of time. They are only intermittent duty and will fail catastrophically if energized too long. Run capacitors are used for continuous voltage and current control to a motor''s windings and are therefore continuous duty.
