The PE447T-250-4-ODP is a powerful electric motor designed for various industrial applications. This particular model boasts a nominal power output of 250 horsepower, making it an ideal choice for heavy-duty applications that require significant torque and power.
The motor operates on a four-pole design, which is characterized by its high starting torque and relatively low speed. In this case, the motor's rotational speed is 1790 revolutions per minute (RPM). This speed is suitable for many industrial applications, providing a balance between power and efficiency.
The motor is designed for phase 1790 voltage, specifically 460 volts. This North American standard voltage is commonly used in industrial settings, ensuring compatibility with existing power systems.
The PE447T-250-4-ODP is also equipped with an ODP (Open Drip Proof) rating. This means that the motor is protected against the entry of solid foreign objects larger than 0.75 mm, and it is also protected against light splashing of liquids. This makes it suitable for use in environments where there is a risk of exposure to liquids or dust.
In summary, the PE447T-250-4-ODP is a robust and versatile electric motor that offers a high power output, suitable rotational speed, and protection against foreign objects and liquids. Its four-pole design provides high starting torque, while its North American voltage standard ensures compatibility with existing power systems. This motor is an excellent choice for heavy-duty industrial applications.
