Motor Type: Fan motors are often induction motors or shaded-pole motors, designed for continuous operation and reliability.
The type may vary based on the specific application.
Power Supply: Fan motors typically run on single-phase AC power, with common voltage ratings ranging from 110V to 240V, depending on the intended application and geographic region.
Power Rating: The power rating of a fan motor is measured in watts or horsepower (HP). It defines the motor's ability to generate airflow and is selected based on the required cooling capacity.
Speed: Fan motors can have single-speed or multi-speed options, allowing for adjustment of the airflow rate to meet specific requirements.
Enclosure Type: The motor may be open or enclosed. Enclosed motors are better protected against environmental factors, making them suitable for outdoor or industrial applications.
Mounting: Fan motors can be designed for various mounting orientations, including horizontal or vertical mounting, to fit specific installation requirements.
Size: Fan motors come in various sizes, measured in frame sizes or diameter.
The size affects the motor's capacity and physical dimensions.
Efficiency: The efficiency of a fan motor is expressed as a percentage and represents how effectively it converts electrical power into mechanical power. High-efficiency motors are desirable for energy savings.
Noise Level: The noise level is measured in decibels (dB) and indicates how quiet or noisy the motor is during operation. Lower noise levels are often preferred in residential and office environments.
Temperature Rating: Fan motors have temperature ratings to ensure they can operate within a specified temperature range without overheating or experiencing performance issues.
Protection Features: Many fan motors include protection features such as thermal overload protection, which shuts down the motor in case of overheating, preventing damage.
Shaft Type: The motor shaft can be single or double-ended, and it may be threaded or designed for a specific type of fan blade attachment.
