Washing Machine Capacitors Manufacturers

AnHui JuanKuang Electric Co., Ltd. has produced film capacitors in Ningguo, Anhui Province since 1995, and washing machine capacitors form a dedicated line inside our AC motor capacitor range. We manufacture CBB60 cylinder plastic-case and CBB65 cylinder aluminum-case capacitors from metallized polypropylene film, keeping metallizing, winding, welding, spray coating, assembly and final test within one integrated production system. Appliance producers in North America, Europe and Asia fit these capacitors on single-phase washer drive motors, where the part sets the phase shift for the auxiliary winding and also supports filtering, voltage stabilization and quieter motor running.

What a Motor Capacitor Does in a Washer

A single-phase washer motor cannot start or run smoothly on its main winding alone. The capacitor delays current in the auxiliary winding so the two windings produce a rotating field with usable torque, and it keeps that field stable through wash, rinse and spin phases. Because the capacitor sits directly in the motor circuit, its capacitance value, stability over temperature and ability to clear internal faults define how the washer behaves in the field.

• Stores and releases electrical energy in step with the motor's AC cycle
• Improves starting and running performance of the drive motor
• Reduces motor noise and vibration transferred into the cabinet
• Filters the motor circuit and helps hold voltage steady under load
• Tunes the winding phase angle so torque stays consistent across the cycle

Our Position in Washing Machine Capacitors

Our standing as Washing Machine Capacitors Manufacturers rests on process ownership rather than assembly alone. The metallizing line runs German CAP coating equipment and winding uses Swiss automatic machines, so film deposition, winding tension and element geometry are controlled in-house before a capacitor ever reaches a washing machine harness. Every element then passes welding, spray coating, assembly and automated test stations inside the same plant.

Metallized polypropylene film gives these parts their working character: favorable high-frequency behavior, stable performance across temperature, strong self-healing after local dielectric breakdown, and a compact build that fits a motor bracket. That combination is why the same CBB series serves our AC Motor Capacitors range across appliance, fan, pump and compressor duties.

Washing Machine Capacitor Range and Configuration Scope

Two case formats cover most washer motor envelopes. Both are wound from metallized polypropylene film and can be specified to a motor drawing, with capacitance, rated voltage, dimensions and packaging treated as configurable rather than fixed catalogue values.

Specifications We Fix Before Production

A washing machine capacitor is only correct when the electrical value and the mechanical envelope are both right. We confirm the following points with the motor or platform drawing before a winding schedule is released.

• Capacitance and tolerance — nominal value plus the acceptable band for the motor's start and run behavior
• Rated AC voltage and frequency — matched to the mains supply and the motor's working duty
• Case format — plastic cylinder or aluminum cylinder, with diameter, height and base profile
• Connection — lead length, exit direction, termination style and any harness connector interface
• Marking and traceability — print content, date or lot coding, orientation on the can
• Packaging — bulk cartons, layer pads, pallet format and labeling that suits the customer's line

Process Control, Testing and Acceptance

Full-process quality management runs from incoming film to the loading dock. Each production step is followed by an inspection point, semi-finished capacitors are tested before assembly is closed, and finished units undergo 100% final inspection against customer requirements and international standards in our automated testing area. Standardized procedures cover raw material inspection, process parameter control, in-line inspection and shipment quality control.

Acceptance is agreed at the proposal stage: capacitance and tolerance verification, voltage withstand, insulation and外观 checks, plus any additional customer-defined criteria. Where a project requires a first-article report or a sample approval cycle, we build the sample from the same drawing and process route that will be used in mass production.

Installation and Line Integration

The capacitor is usually the last component fitted to a motor bracket, so its geometry and lead routing affect the whole assembly station. These are the points we align with the customer's process engineers during configuration.

• Mounting orientation, clamp or strap position, and the clearance needed around the can
• Lead length and exit angle so the harness reaches the terminal block without tension
• Terminal loading limits — connections made without twisting or pulling the terminal
• Ambient temperature around the motor and airflow inside the washer cabinet
• Handling and storage before the assembly station, including protection of leads and case

OEM and ODM Customization

Customized production is our core business, not an exception to a fixed catalogue. Capacitance, voltage, dimensions and packaging can all be specified, and we develop and manufacture to customer drawings or supplied samples. This covers platform-specific washer motors, replacement market parts and second-source programmes where the new capacitor must drop into an existing bracket unchanged.

Information We Use to Configure Your Solution

Compliance, Documentation and Export Supply

We follow international quality and environmental standards and hold ISO9001 and ISO14001 certification, with product approvals including UL, VDE, CE and CQC that support market entry in North America and Europe. Our capacitor products comply with RoHS, REACH, TSCA and POPs requirements, and a life cycle compliance statement is maintained for the range.

Production capacity is 40 million capacitors a year, with annual export volume of AC and refrigerator compressor capacitors exceeding 10 million units. Our products are supplied to more than 30 countries and regions, including the United States, Germany, Japan, Spain, Italy, the United Kingdom, South Korea, Australia and Canada, and we have supported international brands such as GE, Electrolux, Samsung and Whirlpool. Shipments move by sea from Ningbo or Shanghai, with air freight arranged for urgent releases.

Frequently Asked Questions

Which capacitor types do you supply for washing machine motors?

We produce CBB60 capacitors in a cylinder plastic case and CBB65 capacitors in a cylinder aluminum case, both wound from metallized polypropylene film. Custom OEM and ODM versions are built when a platform needs a different envelope, connection or marking.

Can capacitance, case size and packaging be customized?

Yes. Capacitance, voltage, dimensions and packaging are all configurable, and we develop parts from customer drawings or physical samples. Lead length, terminal style and label content are agreed together with the mechanical envelope.

What certifications back your washing machine capacitors?

Our manufacturing systems are certified to ISO9001 and ISO14001, and our products carry UL, VDE, CE and CQC approvals. The CBB65 AC motor capacitor obtained VDE A-level certification in 2015. Materials also meet RoHS, REACH, TSCA and POPs requirements.

How is quality controlled on this line?

Inspection follows every production process, semi-finished elements are tested before assembly, and finished capacitors receive 100% final inspection in our automated testing area against customer requirements and international standards. Raw material inspection and shipment quality control complete the chain.

What do you need to prepare a proposal?

Motor voltage, frequency, capacitance and tolerance, the bracket or envelope drawing, connection and lead details, ambient conditions, annual volume and destination market. With those inputs we return a defined configuration, sample plan and packaging specification.
