Efficient Durable Single-Phase Motor

Overview of Product

With a rated power of 2.2KW (2200W), operating voltage of 220V, and rotational speed of 2820 R/min, this motor delivers consistent performance while adhering to strict quality standards. Its core advantages lie in the use of 100% copper wire coil and national standard rotor, which together minimize energy loss, reduce operational noise, and extend the motor’s service life. Additionally, the motor features an aluminum housing that enhances heat dissipation and reduces overall weight, ensuring easy installation and adaptability to limited-space environments. Whether powering small-scale machinery or heavy-duty household appliances, the ML-90L-2 balances efficiency, durability, and practicality.

Product Features

Core Electrical Components

100% Copper Wire Coil: The motor’s coil is crafted from pure copper, which offers superior electrical conductivity compared to aluminum alternatives. This design reduces heat generation during long-term operation, lowers energy consumption by 8-12% versus standard copper-clad aluminum coils, and prevents premature coil burnout.

National Standard Rotor: Manufactured in compliance with national industrial standards, the rotor features high-precision machining that minimizes operational jitter. This stability ensures the motor maintains consistent 2820 R/min speed even under variable loads, avoiding damage to connected equipment (e.g., pumps, compressors).

High-Density Seiko Bearing: Equipped with high-density precision bearings, the motor exhibits excellent wear resistance and moisture resistance. The bearings operate with minimal friction, reducing operational noise to less than 65dB and extending maintenance intervals to 12 months under normal use.

Structural & Operational Advantages

Aluminum Housing: The lightweight aluminum casing not only simplifies transportation and installation but also provides efficient heat dissipation. It effectively transfers heat generated by internal components, keeping the motor’s surface temperature below 75℃ during continuous operation.

Cold-Rolled Steel Sheet: The motor’s stator core uses high-quality cold-rolled steel sheets, which enhance magnetic conductivity and reduce iron loss. This design further boosts energy efficiency and ensures the motor meets low-temperature operation requirements (adaptable to -10℃ to 40℃ environments).

S1 Duty Rating: Classified as S1 (continuous duty), the motor can run 24/7 without overheating, making it suitable for non-intermittent tasks such as water pump circulation and conveyor belt operation.

Applications

Light Industrial Machinery

The ML-90L-2 is widely used in small-scale industrial equipment that relies on single-phase power, including:

Small air compressors for workshops and garages;

Woodworking machines (e.g., table saws, sanders) in small furniture factories;

Small conveyor systems for packaging lines in retail or logistics facilities.

Domestic & Commercial Equipment

For high-power household and commercial needs, the motor is an excellent fit for:

Large exhaust fans in commercial kitchens, warehouses, or greenhouses;

Heavy-duty washing machines and dryers in laundromats;

Water pumps for residential water supply systems or small-scale irrigation projects.

FAQ

What voltage range is compatible with the ML-90L-2 motor?

The motor is designed exclusively for 220V single-phase alternating current (AC). It is not compatible with 380V three-phase power or 110V low-voltage systems. If the power supply fluctuates (e.g., in rural areas), we recommend using a voltage stabilizer (rated for 220V/15A or higher) to protect the motor from damage.

What does the S1 duty rating mean for daily use?

S1 (continuous duty) indicates the motor can operate continuously for an unlimited period under rated load without overheating. This makes it suitable for tasks that require non-stop operation, such as water circulation pumps or industrial exhaust fans. Avoid using the motor in S2 (short-time duty) or S3 (intermittent duty) scenarios, as this may cause unnecessary wear on internal components.

How to maintain the motor to extend its service life?

Bearing Maintenance: Lubricate the bearings with high-temperature resistant grease every 6-12 months (depending on usage frequency) to reduce friction.

Coil Inspection: Annually check the coil’s insulation layer for cracks or moisture. If the motor is used in humid environments, wipe the aluminum housing monthly to prevent corrosion.

Cleaning: Regularly remove dust from the motor’s surface and air vents to ensure proper heat dissipation. Avoid using water directly on the motor; use a dry brush or compressed air instead.
