Single Phase Fractional Horsepower Premium Efficiency Motor (Two capacitors)

Why do SINGLE PHASE FRACTIONAL HORSEPOWER PREMIUM EFFICIENCY MOTOR need to use two capacitors? What are the functions of these two capacitors?

The reason why SINGLE PHASE FRACTIONAL HORSEPOWER PREMIUM EFFICIENCY MOTOR uses two capacitors is mainly to improve the starting performance and operating efficiency of the motor. This kind of motor is usually used in situations where smaller power output is required, and the single-phase power supply itself cannot provide sufficient starting torque, so a capacitor is needed to assist the starting and running of the motor.
These two capacitors each play an important role in the electric motor:
Start capacitor (Run Capacitor):
Function: When the motor starts, the starting capacitor forms a phase difference with the motor winding, generating a rotating magnetic field to help the motor start smoothly from a stationary state.
Features: Starting capacitors usually have larger capacities to provide sufficient starting torque. After the motor is started, the starting capacitor may continue to participate in operation, or it may be automatically disconnected through a centrifugal switch or other means after the motor reaches a certain speed.
Run Capacitor:
Function: During the operation of the motor, the running capacitor is used to improve the power factor of the motor, increase the efficiency of the motor, and reduce current harmonics to make the motor run more smoothly.
Features: The capacity of the running capacitor is usually smaller than that of the starting capacitor, and it will continue to work throughout the entire operation of the motor.
By rationally using these two capacitors, SINGLE PHASE FRACTIONAL HORSEPOWER PREMIUM EFFICIENCY MOTOR can achieve high starting performance and operating efficiency under single-phase power supply, while maintaining low energy consumption and small size. It is suitable for various small needs Application scenarios of power output.
It should be noted that the selection and configuration of capacitors need to be based on the specific specifications and requirements of the motor to ensure the performance and safety of the motor. At the same time, during use, the status of the capacitors should be checked regularly, and aging or damaged capacitors should be discovered and replaced in time to ensure the normal operation of the motor.
