Motor run capacitors are an essential component of single-phase electric motors. Motor run capacitors help to shift the phase of incoming power, creating a secondary phase, which results in the motor running more efficiently and with greater torque. Run capacitors are typically used with medium-to-high torque applications required for air conditioners, auger drives, compressors, and conveyors. However, it is important to note that not all single-phase motors require run capacitors. In some cases, such as with fan motors, they are not necessary.

One of the common issues that arise with single-phase motors is the malfunctioning of run capacitors. When a motor is running but drawing high current, has low torque, or blows fuses after a short time, it is likely that the run capacitor is faulty. In such cases, it is essential to replace the motor run capacitor to ensure optimal motor performance.

Replace run capacitor

At Kesheng, we understand the importance of selecting the correct run capacitor. When replacing a run capacitor, it is essential to consider three primary factors: capacitance, voltage rating, and size. Capacitance is measured in microfarads and should closely match the original capacitor. The voltage rating of the replacement capacitor should be equal to or higher than the original, but size should also be considered.

As a Motor run capacitors supplier, We offer a wide range of run capacitors for purchase on our website, and our knowledgeable staff is always available to assist you in selecting the appropriate capacitor for your motor.
