This type of motor, as the name suggests, employs two capacitors in its design – a start capacitor and a run capacitor. The start capacitor provides an initial boost of energy at startup, while the run capacitor continues to provide energy throughout the motor’s operation. How Capacitor-Start Capacitor-Run Motors Work
Once the motor reaches a specific speed, the start capacitor gets disconnected from the circuit by a switch. After this, the run capacitor, connected in parallel to the auxiliary winding, takes over. It provides the required phase shift for the motor to continue operation. Key Advantages of Capacitor-Start Capacitor-Run Motors
The start capacitor provides an initial boost of energy at startup, while the run capacitor continues to provide energy throughout the motor’s operation. How Capacitor-Start Capacitor-Run Motors Work The main principle behind a Capacitor-Start Capacitor-Run Induction Motor involves creating a rotating magnetic field within the motor.
A capacitor start motor will not run without a rated capacitor connected in series with the starting winding because the capacitor is needed to create the necessary phase shift to start the motor.
Start capacitors increase motor starting torque and allow a motor to be cycled on and off rapidly. Start capacitors are designed for momentary use. Start capacitors stay energized long enough to rapidly bring the motor to 3/4 of full speed and are then taken out of the circuit.
A capacitor is required for a single-phase motor to provide the necessary phase shift to start the motor and to improve its running efficiency. In a 1-phase motor, the starting torque is essential to overcome the initial inertia and bring the motor to its operating speed.
