The 48 Frame Dripproof Single-Phase Motor is an innovative power solution designed for harsh industrial environments. It stands out among similar single-phase motors with its compact 48-frame structure. Compared with conventional open motors, this product adopts a fully enclosed drip-proof (ODP) design. The IP23 protection level can effectively resist liquid dripping and dust intrusion within 60° in the vertical direction, which is particularly suitable for humid and dusty scenes such as food processing and agricultural irrigation. With dual certifications of CSA&CUS and UL, its compatibility in the North American market far exceeds that of competitors that only meet basic standards. The unique thermal protection module can automatically monitor the winding temperature and achieve continuous and stable output with the F-class insulation system, extending the service life by 40% compared to traditional A/B-class insulation motors. As one of the very few NEMA N-type motors that covers the full power range from 1/10HP to 1HP, its modular design can seamlessly adapt to the upgrade needs of various equipment such as conveyors and compressors.

[Application scenarios]
This motor is particularly suitable for medium and low power scenarios that require moisture and dust protection, such as commercial refrigeration equipment (refrigerator compressors), automated packaging line drive units, and water treatment circulation pumps. Its compact size can directly replace old AO2 series motors without modifying the mounting base.
