Ningguo Kingcool Import and Export Co., Ltd is a China-based manufacturer of metalized polypropylene film capacitors, producing the CBB60 series for washing machine motors. Our annual capacity of 10 million units supports OEM, wholesale, and aftermarket programs across the Middle East, Africa, South America, and Southeast Asia.
Washing Machine Capacitor Manufacturing at Kingcool
As a Washing Machine Parts-Capacitor For M/W Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
We combine industry and trade under one roof, with high-precision slitting and winding equipment, automated production lines, and in-line testing equipment. Every Capacitor For M/W is built around the phase-shift requirements of single-phase induction motors used in washers, spin dryers, and pump drives.
Our capacitor range sits within a broader appliance and HVAC parts portfolio, so washing machine manufacturers and service distributors can source capacitors, motors, timers, and control components through one procurement channel.
The CBB60 Motor Capacitor Range
The CBB60 is a metalized polypropylene film capacitor in a plastic insulating shell with epoxy resin potting and vegetable-oil impregnation. It is designed for continuous AC operation in washing machine motors, where capacitance stability directly affects starting torque and running efficiency.
- Dielectric: metalized polypropylene film with self-healing capability
- Construction: plastic case, epoxy potting, metal shell options
- Impregnation: vegetable oil for thermal and electrical stability
- Application: start and run duty in single-phase washer motors
Technical Parameters and Performance
Our metalized series is specified for lower loss and longer service life than standard-grade film capacitors. The table below summarizes the parameters we verify with our testing equipment.
| Parameter | Standard Grade | Kingcool Metalized Series |
|---|---|---|
| Dissipation Factor (tan δ) | ≤ 0.0040 at 1 kHz | ≤ 0.0020 (ultra-low loss) |
| Self-Healing Ability | Limited | Excellent (automatic fault isolation) |
| Capacitance Tolerance | ±10% | ±5% (high precision) |
| Operating Life (Class B/C) | 3,000–10,000 hours | Up to 30,000 hours |
| Safety Rating | Basic P0 | P2 explosion-proof (segmented film) |
Application Fit in Washing Machine Systems
Single-phase induction motors cannot generate a rotating magnetic field without a phase shift. The capacitor in series with the start or auxiliary winding creates the displaced field that produces starting torque and maintains efficient rotation during the wash and spin cycles.
- Start capacitors: deliver a high burst of torque to overcome the inertia of a heavy laundry load
- Run capacitors: remain in circuit to improve power factor and motor efficiency
- Pump and drain motors: require stable capacitance for reliable switching under frequent start/stop cycles
Our capacitors are also used in other single-phase motor applications across our capacitor product range, including air-conditioner fan motors and refrigeration compressors.
Configuration and Customization
We configure each capacitor to the motor it drives. Capacitance value, voltage rating, case dimensions, terminal type, and mounting style are matched to the washer platform and the motor manufacturer's specification.
- Capacitance values from standard washer motor ratings upward
- Voltage ratings matched to regional mains supply
- Case and terminal options for drop-in replacement or new design
- Lead length and connector type to suit the wiring harness
Quality Control and Acceptance
Our production process uses automated slitting and winding, with real-time monitoring during manufacturing. Testing equipment verifies capacitance, dissipation factor, and insulation resistance before packing.
- Incoming metalized film inspection
- In-process capacitance and loss monitoring
- Final electrical test on every unit
- Batch traceability through production records

Frequently Asked Questions
What is the function of a capacitor in a washing machine motor?
The capacitor creates a phase shift between the main and auxiliary windings, generating the rotating magnetic field needed for starting torque and efficient running in single-phase induction motors.
Why choose metalized polypropylene film over other capacitor types?
Metalized film offers self-healing capability, lower dissipation factor, and longer operating life compared to electrolytic or standard film designs, which is important for the frequent start/stop cycles of washing machines.
Can you produce capacitors to match a specific motor brand?
Yes. We configure capacitance, voltage, case dimensions, and terminals to the motor specification. Provide the motor details and we will match the capacitor to the application.
What information is needed for a quotation?
Motor specification, required capacitance and tolerance, case and terminal details, annual volume, and delivery schedule. This allows us to prepare an accurate proposal.
Do you supply other washing machine parts?
Yes. Our range includes gear boxes, drain motors, pumps, timers, inlet valves, hoses, and other components, supporting one-stop procurement for appliance manufacturers and distributors.
