Manufactured by Taizhou Julante Electric Technology Co., Ltd., this motor stands out with its 2.2KW/3HP rated power, 2880R/min high speed, and 85.9% energy efficiency—ranking it in energy efficiency class 3 to meet global energy-saving standards. Operating at 380V voltage and 50HZ frequency, it delivers strong torque for driving large equipment, while its aluminum shell (a lightweight alternative to traditional steel) reduces overall weight without sacrificing strength. The IP55 protection rating shields it from dust and water, and CSA certification ensures compliance with international safety norms. Whether powering heavy machinery or industrial ventilation systems, the M5-90L-2 motor combines power, efficiency, and durability to optimize operational productivity.
With an energy efficiency of 85.9% and energy efficiency class 3, the motor minimizes energy waste, lowering long-term operational costs for industrial users. Its 2880R/min rated speed is engineered for high-torque output, making it suitable for equipment that requires fast, consistent rotation—such as centrifugal pumps or heavy-duty conveyors. The motor’s power factor is optimized to reduce reactive power consumption, further enhancing energy efficiency in grid-connected applications.
Unlike many heavy-duty motors with steel casings, the M5-90L-2 features an aluminum shell that reduces the motor’s weight (net weight: approximately 0.8516kg for key components; total weight varies by configuration) while maintaining excellent heat dissipation. Aluminum’s thermal conductivity accelerates heat transfer, preventing overheating during continuous operation. Additionally, the aluminum shell is corrosion-resistant, making the motor suitable for humid or coastal industrial environments where steel may rust.
The motor incorporates a national standard high-precision rotor with minimal jitter, ensuring stable operation and reducing wear on the driven equipment. A 100% COPPER WIRE COIL is used to maximize electrical conductivity and reduce energy loss, while a high-quality cold-rolled silicon steel sheet in the stator lowers core losses and magnetic noise. High-density Seiko bearings, treated for rust and moisture resistance, ensure smooth shaft rotation and extend the motor’s service life to over 10,000 operating hours under normal conditions.
The IP55 protection rating safeguards the motor against dust ingress (preventing coil contamination) and water jets (from any direction), making it suitable for use in dusty workshops or outdoor covered areas. A fan cowl and integrated heat dissipation system further enhance thermal management, keeping the motor within safe temperature ranges even under full load. The fixed base is designed for secure mounting, reducing vibration and ensuring alignment with driven equipment—critical for preventing premature component failure.
The motor’s 2.2KW/3HP power and 2880R/min speed make it ideal for driving heavy-duty industrial machinery, such as large conveyors, mixing machines, and centrifugal separators. Its high torque output ensures these machines can handle heavy loads (e.g., bulk materials in mining or construction), while the aluminum shell’s heat dissipation prevents overheating during long production runs.
In water treatment plants and large-scale pumping systems, the motor’s IP55 protection and corrosion-resistant aluminum shell are key advantages. It can power large water pumps (e.g., for irrigation or wastewater treatment) without being damaged by moisture or chemical fumes, while its high efficiency reduces energy costs for continuous pump operation.
For industrial HVAC ventilation units (e.g., large exhaust fans or air handlers), the motor’s high speed and stable performance ensure efficient air circulation. The low noise operation (thanks to precision bearings and balanced rotor) minimizes disruption in industrial facilities, and the energy efficiency class 3 rating helps reduce the HVAC system’s overall energy footprint.
In agriculture, the motor can power heavy-duty equipment like grain dryers, large-scale irrigation pumps, and feed mixers. Its durable construction withstands the dust and vibration common in farm environments, while the 380V voltage compatibility matches the electrical systems of most agricultural facilities.
Energy efficiency class 3 indicates the motor meets basic global energy-saving standards, with an 85.9% efficiency that reduces energy waste compared to lower-class motors. Higher classes (e.g., class 2) offer slightly higher efficiency (typically 87%+), but they come at a higher cost. For applications with moderate usage (e.g., 8–12 hours/day), class 3 provides a cost-effective balance of efficiency and affordability. For 24/7 operations, we recommend upgrading to a higher-efficiency model.
The aluminum shell offers two key benefits: lightweight design and superior heat dissipation. Aluminum is 30% lighter than steel, making the motor easier to install and handle—especially in overhead or tight-space applications. Additionally, aluminum’s thermal conductivity is 3x higher than steel, which accelerates heat transfer away from the coil and rotor, preventing overheating and extending the motor’s lifespan.
Yes, but the motor’s performance may be slightly affected at altitudes above 1000 meters. At higher altitudes, lower air density reduces heat dissipation efficiency. For altitudes between 1000–3000 meters, we recommend derating the motor by 5–10% (e.g., using the 2.2KW motor for 2.0KW loads) to prevent overheating. For altitudes above 3000 meters, contact our technical team for a customized high-altitude version.
Each M5-90L-2 motor has a unique serial number (e.g., NO: JLT26062) printed on the nameplate, which is used for warranty registration and tracking. The motor comes with a 12-month warranty from the date of purchase, covering defects in materials and workmanship. Please keep a record of the serial number and proof of purchase for warranty claims.
Yes, the motor is fully compatible with standard soft starters rated for 2.2KW/3HP three-phase motors. Soft starters help reduce inrush current during startup, which protects the motor’s coil and extends its lifespan—especially useful for equipment with high inertia (e.g., large fans or mixers). When installing a soft starter, ensure it is configured to match the motor’s 380V voltage and 50HZ frequency.
