Product Features

Ultra-High Energy Efficiency

IE3 Efficiency Standard: Operating as a certified IE3-rated motor, this unit achieves a remarkable minimum efficiency of 85.5% (specifically engineered for 1.5KW, 2-pole motors)—which translates to a 5-8% higher performance yield than older IE2 motors. To illustrate the financial impact, a YE3 1.5KW motor operating 10 hours daily can save approximately 200-300 kWh annually compared to an IE2 equivalent. You will physically notice the difference: the exterior remains noticeably cooler to the touch due to drastically reduced thermal waste. This superior efficiency also makes the motor fully compliant with strict energy regulations across major regions like the EU, USA, and China, completely eliminating compliance barriers for international trade.

Optimized Magnetic Circuit: The internal architecture of the motor’s stator and rotor has been meticulously engineered to generate an exceptionally uniform magnetic field. This advanced configuration actively minimizes magnetic leakage and reduces iron loss. Consequently, this design ensures high efficiency even when the motor operates at 50-70% of rated load, a fluctuating operational state very common in dynamic commercial applications.

Compact & High-Performance Components

100% Copper Wire Coil: The internal winding utilizes densely packed, high-purity copper wire coated with a thick, resilient insulation layer. This premium material choice dramatically enhances electrical conductivity, mitigates internal heat generation, and actively resists breakdown during unexpected voltage fluctuations. This structural design physically prevents coil burnout and guarantees a smooth, consistent power output of 1.5KW under heavy loads.

High-Precision Rotor: Each rotor undergoes rigorous dynamic balancing and precision machining to achieve an incredibly tight, minimal air gap (0.2-0.3mm) with the stator. This microscopic tolerance drastically reduces operational jitter (maintaining vibration < 0.08mm) and sustains a perfectly stable 2880 R/min speed. Such precision is critical for sensitive equipment like medical pumps or high-speed packaging machines that demand absolute mechanical accuracy.

Rust-Proof Moisture-Proof Bearings: The motor is equipped with heavily sealed bearings treated with specialized anti-corrosion coatings. These heavy-duty components are highly resistant to ambient humidity, airborne dust, and minor chemical exposure on the factory floor. Designed for longevity, these premium bearings require lubrication only once every 12 months, significantly reducing your ongoing maintenance efforts.

Safety & Structural Advantages

18KG Lightweight Design: Featuring a highly optimized, lightweight structure (weighing in at 30% lighter than comparable IE2 motors), this 18KG unit greatly simplifies logistical transportation and physical installation. It is particularly advantageous for integration into equipment with strict weight restrictions, such as mobile medical carts or small overhead conveyor systems.

Cast Iron Casing: Despite its impressive light weight, the motor is encased in a thick, highly durable cast iron casing. This solid shell provides exceptional impact resistance against accidental factory floor collisions and acts as a superb acoustic dampener. Operational noise is strictly kept below 68dB—producing only a smooth, low-frequency hum—making it highly suitable for noise-sensitive environments like testing laboratories or medical facilities.

IP55 Protection Rating: The completely sealed enclosure ensures the motor is entirely dustproof and highly protected against low-pressure water jets. This allows for confident, continuous use in machining workshops with moderate dust levels or busy commercial kitchens prone to occasional liquid splashes.

Comprehensive Certification: Beyond its core design, the motor meets CSA’s rigorous safety standards, successfully passing exhaustive tests for insulation integrity, overload protection, and thermal temperature resistance. Supported by an ISO-certified quality management system and additional CE and CCC compliance, it ensures universally safe operation in both demanding industrial and commercial settings.

Applications

Small Industrial Machinery

The highly adaptable YE3 series is widely utilized across various low-power industrial equipment sectors that demand a strict balance of electrical efficiency and mechanical precision:

• Packaging Machines: Effortlessly drives continuous conveyor belts, thermal sealing rollers, and automated labeling systems in fast-paced packaging lines. By leveraging its superior energy efficiency, facilities can drastically reduce electrical overhead costs during non-stop, 24/7 continuous operation.

• Textile Auxiliary Equipment: Reliably operates small yarn winders, spinning frames, or thread tensioners in busy textile factories. The motor's exceptionally low vibration and stable rotational speed actively prevent delicate thread breakage, minimizing material waste.

Medical & Commercial Equipment

Thanks to the motor’s whisper-quiet acoustic profile and stringent safety certifications, it is perfectly suited for integration into highly sensitive, human-facing environments:

• Medical Equipment: Provides dependable power for small air compressors within critical oxygen concentrators, precision laboratory pumps for accurate liquid transfer, or low-speed medical centrifuges. In these settings, absolute mechanical reliability and low ambient noise are non-negotiable requirements.

FAQ

What is the difference between IE3 and IE2 motors, and why choose IE3 for small-power applications?

Upgrading to IE3 motors (like our advanced YE3 series) offers significantly higher electrical efficiency than older IE2 motors, a benefit that remains highly impactful even for small-power (1.5KW) applications. The core operational differences include:

Efficiency: IE3 motors are precision-engineered to maintain a minimum efficiency of 85.5% (specifically for 1.5KW, 2-pole configurations), whereas legacy IE2 motors typically hover around a less efficient 80-82%.

Energy Savings: When analyzing long-term utility expenses, a 1.5KW motor running 8 hours daily in an IE3 model saves approximately ~150-200 kWh/year compared directly to an IE2 unit. This consistent reduction adds up to substantial, measurable cost savings over the motor’s projected 10-year lifespan.

Regulatory Compliance: Numerous global markets (e.g., the EU, USA) have legally phased out IE2 motors for specific industrial applications, making IE3 a strict, mandatory choice for international equipment imports. Even for localized domestic use, adopting IE3 motors perfectly aligns with modern corporate sustainability goals and carbon reduction targets.

What does the 2880 R/min speed indicate, and which equipment benefits from this speed?

The value of 2880 R/min represents the actual rated speed of a standard 2-pole three-phase motor under full load (where the theoretical synchronous speed = 3000 R/min, accounting for a natural magnetic slip rate of ~4%). This exceptionally high rotational speed is mechanically ideal for equipment that inherently requires rapid, continuous rotation, such as:

Fans & Blowers: The rapid impeller speed effectively moves massive air volumes, making it highly suitable for facility ventilation, exhaust systems, or active cooling towers.

Centrifugal Pumps: The fast, continuous rotation generates necessary high water pressure, which is ideal for driving small-scale municipal or industrial water supply systems.

Grinding Machines: The sustained high speed ensures a flawlessly smooth, precise grinding finish on tough raw materials like metal alloys or hardened plastics.

Application Note: Always avoid using this specific high-speed motor for heavy equipment requiring low-speed, high-torque output (e.g., large, heavily loaded material conveyors). For those applications, pairing this unit with a compatible gear reducer, or selecting a dedicated lower-speed motor (e.g., 1470 R/min), is the technically sound and more suitable approach.
