With a rated power of 22KW, operating voltage of 380V three-phase AC, rotational speed of 1470 R/min, and compliance with the IE2 efficiency standard, this motor delivers exceptional performance while minimizing energy consumption. It features a rugged cast iron casing, IP55 protection rating, and CSA security certification, ensuring durability in harsh workshop environments (e.g., concrete plants, manufacturing facilities). The YE2 series is built with premium components—including 100% copper wire coils, high-quality cold-rolled silicon steel sheets, and high-precision national standard rotors—which reduce operational noise, lower heat generation, and extend the motor’s service life to over 8 years under normal use. Whether powering concrete mixers, large fans, or high-pressure pumps, this motor balances heavy-duty performance with eco-friendly efficiency.
IE2 Efficiency Standard: As an IE2-rated motor, it meets international energy efficiency requirements, consuming 10-15% less electricity than standard IE1 motors. For example, a YE2 22KW motor operating 8 hours daily can save approximately 500-800 kWh of electricity annually, significantly reducing operational costs.
Low Iron Loss Design: The stator core uses high-quality cold-rolled silicon steel sheets, which have low magnetic hysteresis loss. This design minimizes heat generation during operation, allowing the motor to maintain efficiency even under partial load conditions.
100% Copper Wire Coil: The motor’s winding is made of pure copper, which offers better conductivity and heat resistance than aluminum coils. This reduces energy loss and prevents coil overheating, even when the motor operates at 110% of rated load for short periods.
High-Precision National Standard Rotor: The rotor is manufactured to strict national tolerances, ensuring minimal air gap between the rotor and stator. This reduces magnetic leakage, lowers operational jitter (vibration amplitude < 0.1mm), and maintains stable 1470 R/min speed—critical for equipment like concrete vibrators that require consistent performance.
Rust-Proof Seiko Bearings: Equipped with high-density, moisture-proof bearings, the motor resists corrosion in humid environments (e.g., concrete plants with water splashes). The bearings have a service life of over 20,000 operating hours, reducing maintenance frequency.
Cast Iron Casing: The thickened cast iron housing provides superior impact resistance and sound insulation. It reduces operational noise to less than 72dB, creating a more comfortable working environment compared to aluminum-cased motors.
IP55 Protection Rating: The motor is dustproof and protected against low-pressure water jets, making it suitable for use in dusty concrete plants, outdoor workshops, or facilities with frequent cleaning.
CSA Certification: The motor has passed CSA’s strict safety tests, including insulation resistance, temperature rise, and overload protection, ensuring compliance with North American and global industrial safety standards.
The YE2 series is a staple in construction and concrete-related operations, powering:
Concrete Mixers: Provides the high torque needed to mix aggregate and cement, ensuring uniform concrete quality.
Concrete Vibrators: Delivers stable 1470 R/min speed to eliminate air bubbles in poured concrete, enhancing structural strength.
Construction Pumps: Powers high-pressure water pumps for site irrigation, dust suppression, or concrete washing.
Beyond construction, the motor excels in powering equipment for fluid and air management:
Large Industrial Fans: Ventilates factories, warehouses, or workshops with high heat or fume levels, using the motor’s high torque to move large air volumes.
High-Pressure Pumps: Operates water supply pumps for industrial facilities or wastewater treatment plants, handling high-flow, high-pressure requirements efficiently.
Air Compressors: Drives medium-sized air compressors for manufacturing lines (e.g., pneumatic tools, packaging machinery) with consistent power output.
The IE (International Efficiency) standard classifies motors by energy efficiency, with IE2 being higher than IE1. An IE2 motor like the YE2 series has a minimum efficiency of 91.5% (for 22KW, 4-pole motors), while an IE1 motor typically has an efficiency of 89-90%. This 1.5-2.5% efficiency gap translates to significant long-term energy savings—especially for motors operating daily. Additionally, IE2 motors meet stricter environmental regulations in regions like the EU, avoiding potential import restrictions.
Yes. The YE2 series is designed for heavy-duty continuous operation (S1 duty rating). When running at full load (22KW), the motor’s temperature rise is controlled below 75K (above ambient temperature), thanks to its efficient cooling and low-loss components. However, we recommend:
Checking the motor’s surface temperature monthly (avoid exceeding 80℃);
Cleaning air vents every 2 weeks to prevent dust buildup;
Lubricating bearings every 6 months to maintain performance.
The YE2 series uses a B3T horizontal mounting design, which is the most common configuration for industrial machinery. The mounting base has pre-drilled holes that align with standard equipment brackets, enabling quick installation. For vertical mounting needs (e.g., some pump systems), contact the manufacturer to customize a B5 vertical mounting flange—modifications may require adjustments to the motor’s bearing and cooling system to ensure stability.
