Three-Phase Dripproof High-Efficiency Motor is designed for industrial and commercial drive applications where stable three-phase power, controlled operating environments, and energy compliance are required. Compared with enclosed fan-cooled motors in the same category, this product uses an Open Drip Proof (ODP) enclosure, allowing effective heat dissipation in clean, dry indoor locations while maintaining protection against limited falling moisture. The motor follows NEMA Design B characteristics, providing predictable starting current and torque behavior that aligns with standard industrial equipment requirements.
With a power range from 1HP to 20HP and multiple pole options (2P, 4P, and 6P), this motor supports a wide range of speed and load demands. The rolled steel frame enhances structural stability, while the insulation system meets Class F standards for thermal performance. Compliance with EPACT (CC) and EEV efficiency regulations ensures alignment with energy-efficiency standards, distinguishing it from non-compliant conventional motors. The motor is suitable for applications requiring consistent operation, standardized mounting options, and certified electrical safety without the need for fully enclosed designs.
