Single Phase Capacitor Running Asynchronous Motors

Product Features

High Efficiency & Low Noise Operation

A core advantage of these motors is their 50%-78% efficiency—a range that outperforms many conventional single-phase motors—directly reducing electricity costs for users. Additionally, their precision-engineered structure limits noise to ≤83 dB(A) (as low as 62 dB(A) for small models like the MY 711-6), making them ideal for noise-sensitive environments such as residential areas, offices, or indoor commercial spaces (e.g., retail store ventilation systems).

Robust Construction & Easy Maintenance

The aluminum housing of the MY series offers excellent corrosion resistance and heat dissipation, ensuring the motor operates stably even in humid or warm conditions (e.g., industrial workshops or outdoor pump stations). Unlike motors with complex starting mechanisms, these units lack a starting switch, simplifying internal structure and lowering the risk of mechanical failures. Routine maintenance only requires basic checks, such as inspecting wiring or lubricating bearings, reducing downtime and maintenance costs.

Wide Voltage Adaptability & Global Compatibility

Tailored for international markets, the motors support 220V rated voltage (a standard in most regions) and comply with strict global certifications including ISO9001, CE, and CCC. This compliance ensures compatibility with electrical systems worldwide, eliminating barriers for buyers in Europe, Asia, the Middle East, and beyond. The consistent adherence to the IEC standard also guarantees uniform performance, so users can rely on the same level of quality regardless of the application.

Strong Load Handling & Stable Torque

With max torque (Tmax/Tn) of 1.5-1.8 times and starting torque (Ts/Tn) of 0.30-0.73 times, these motors handle sudden load changes effectively. This makes them suitable for applications requiring frequent starts and stops, such as household washing machines or industrial small pumps. The capacitor-driven design creates a stable rotating magnetic field, avoiding torque fluctuations that could damage connected equipment.

Applications

Household Appliances

The smooth operation and low noise of Single Phase Capacitor Running Asynchronous Motors make them a perfect fit for household devices. They power essential appliances like refrigerators (maintaining consistent cooling via stable fan operation), washing machines (handling variable load during spin cycles), and air conditioners (driving compressors and indoor fans). For example, the MY 561-4 (0.06 kW, 1370 rpm) is often used in small refrigerators, while the higher-power MY 100L2-4 (3 kW, 1430 rpm) supports large-capacity washing machines.

Industrial Equipment

In industrial settings, these motors are widely deployed in pumps, fans, and small machinery. Their high efficiency and torque stability ensure continuous operation for water circulation pumps (e.g., in factory cooling systems) and exhaust fans (removing fumes from production lines). Models like the MY 90L-2 (2.2 kW, 2830 rpm) are ideal for industrial fans, as their 2830 rpm rated speed delivers strong airflow, while the 1.8x max torque handles occasional blockages in ductwork.

Commercial & Agricultural Use

For commercial applications, the motors power ventilation systems in shopping malls, restaurants, and office buildings—where low noise and energy efficiency are critical. In agriculture, they drive small irrigation pumps (e.g., the MY 632-4, 0.18 kW) for small-scale farms, as their 1370 rpm speed balances water flow and energy use. Additionally, their aluminum housing resists rust from outdoor moisture, extending service life in agricultural environments.

FAQ

What makes Single Phase Capacitor Running Asynchronous Motors stand out from other single-phase motors?

Unlike split-phase or shaded-pole motors, these units use a capacitor to create a persistent phase shift, resulting in higher efficiency (50%-78%), better power factor (0.90-0.95), and smoother operation. They also eliminate the need for a starting switch, reducing mechanical failures and maintenance costs—key advantages for both residential and industrial users.

How does the capacitor improve the motor’s performance?

The capacitor generates a 90-degree phase difference between the main and auxiliary windings, creating a rotating magnetic field instead of a pulsating one. This enhances starting torque (Ts/Tn: 0.30-0.73 times) and ensures stable speed during operation, preventing the "hesitation" common in non-capacitor single-phase motors. The result is reliable performance for applications requiring consistent output, such as pumps or fans.

Can these motors handle high-load applications?

Yes. With rated power up to 3 kW and max torque (Tmax/Tn) of 1.5-1.8 times, they excel in high-load scenarios—including frequent starts/stops (e.g., washing machines) or continuous heavy use (e.g., industrial pumps). However, it’s recommended to match the motor’s rated power and speed to the application’s specific needs (e.g., 3 kW models for large compressors, 0.06 kW models for small fans).

What maintenance steps are required to extend the motor’s lifespan?

Routine maintenance includes three key steps: 1) Check electrical connections every 6 months to prevent loose wiring (a common cause of overheating); 2) Lubricate bearings annually (using high-temperature grease for industrial models); 3) Ensure proper ventilation—keep the motor’s cooling vents free of dust or debris to avoid overheating. Following these steps can extend the motor’s lifespan to 8-10 years.
