CBB60 Run Capacitor Motor Start Capacitor with Wire Lead 250VAC 120uF 50/60Hz

Product Information

Finally, a bad capacitor can cause the motor to make unusual noises or emit strange odors. This is often a sign that the motor is working harder than it should be, and the capacitor is not regulating the voltage correctly.

CBB60 capacitors are commonly used as both start and run capacitors in single-phase AC motors. When the motor is switched on, the start capacitor provides the initial boost of energy needed to get the motor up and running. Once the motor reaches its operating speed, the run capacitor continues to provide a phase shift in the current, helping the motor maintain its speed and efficiency.

Before we dive into the specifics of CBB60 capacitors, it’s important to understand what capacitors are and how they function. A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material, known as a dielectric. When voltage is applied across the plates, an electric field is established, and the capacitor stores electrical charge. One of the primary functions of a CBB60 capacitor is power factor correction. Power factor is a measure of how effectively electrical power is converted into useful work output in an AC circuit. Inefficient power factor can result in increased energy consumption and reduced electrical system efficiency. CBB60 capacitors are used to improve the power factor of AC motors, ensuring that they operate more efficiently and consume less energy. Capacitors are passive electrical components found in almost all electronics applications. Our range includes over 60,000 different capacitors including aluminium, tantalum, polymer, polyester film and ceramic capacitors. We source from globally renowned manufacturers AVX, Murata, KEMET, Panasonic, TDK and many more, so that you can rely on performance. What is a capacitor and what does it do?

Motor run capacitors: Some single-phase AC electric motors require a "run capacitor" to energise the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. Overall, while a motor may technically be able to run without a run capacitor, it is not recommended. The run capacitor is an important component that helps to ensure the motor runs smoothly and efficiently, and without it, the motor is likely to experience a range of issues that can impact its performance and lifespan. If you suspect that your motor is running without a run capacitor or if you are experiencing any issues with your motor, it is best to consult with a qualified electrician or technician to ensure that your motor is operating correctly and safely.

What is a capacitor and what does it do?

There are many different types available with detailed specifications for their required function. The main elements are available in varying materials and these determine many properties of the capacitor. Some factors to consider are: Run capacitors are designed for continuous duty while the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are used. Run capacitors are mostly polypropylene film capacitors. What does a motor run capacitor do? Different Dielectric: The dielectric of starting capacitors is Aluminum foil, while in running capacitors, it is metallized polypropylene film. The capacitor works by creating a phase shift between the motor’s start winding and run winding, which produces a rotating magnetic field. This rotating magnetic field creates the torque needed to start and run the motor. Without the film capacitor, the motor may not be able to start at all, or it may start slowly and run inefficiently. Now let's talk about their differences. The CBB65 capacitor has an aluminum shell and the inside is made of high-purity castor oil to maintain the vacuum and has a cylindrical shape. CBB60 and CBB61 are made of flame-retardant epoxy resin to keep the capacitor cores. Although the shells are all PVC shells, CBB60 is cylindrical and CBB61 is square.
