Start capacitor (Start Capacitor) is also called starting capacitor or starting capacitor:
Typically used for single-phase induction motors. It provides additional torque when the motor starts to help the motor overcome the initial static inertia and reach operating speed.

When the motor starts, the starting capacitor is connected in series with the starting winding to increase the starting torque.
After starting, when the motor reaches a certain speed, the centrifugal switch or electrical switch will disconnect the starting winding and capacitor, leaving only the running winding working.

Startup capacitors usually have higher capacitance values but only work for a short period of time. They must be able to withstand high voltages and release energy quickly.

Enhanced starting performance: The starting capacitor can provide a larger initial current to help the motor start quickly.
Improve efficiency and stability: Running capacitors can smooth current fluctuations, maintain stable operation of electric motors, and improve efficiency.
Reduce power consumption: Capacitors can improve power factor and reduce power consumption.
Common applications include:
Household appliances (such as air conditioners, washing machines, refrigerators)
Industrial equipment (such as fans, pumps, compressors)
Agricultural equipment (such as irrigation pumps)
The selection of capacitors for motors in different applications will vary depending on the type, power and working environment of the motor.
Install:
Select the appropriate capacitance value and withstand voltage value according to the power and voltage of the motor.
The required capacitor size is usually indicated on the motor nameplate.
replace:
Check capacitors regularly for bulges, leaks, or other signs of damage.
Use a multimeter to measure the capacitance value and make sure it is within the specified range.
Safety Precautions:
Power-off operation: Before checking or replacing the capacitor, be sure to disconnect the power supply to ensure safety.
Discharge treatment: The starting capacitor may still be charged after use and needs to be discharged through appropriate methods.
