In China, the machinery for gas compression and gas delivery is usually referred to as a fan. Fan motors are divided into household fan motors and industrial fan motors according to the application environment; single-phase fan motors and three-phase fan motors according to the type of power supply; induction motors and brushless motors according to the motor structure. There are many kinds. It is widely used in life and work, improving our quality of life.
Because there are many types of fans, the test equipment also corresponds to them. Single/three-phase AC motors are divided into motor stator test systems, cast aluminum rotor test systems, and motor test systems; brushless motors are divided into stator test systems, permanent magnet rotor test systems, motor control test systems, and motor loading test systems; The dynamometer test system used in the laboratory; according to the motor production process, online test or offline test can be selected. The test items include AC Hi-pot, insulation resistance, surge, multi-speed power, low voltage test, overvoltage test, loading test, FG test, etc.
AIP focuses on global motor testing and provides one-stop motor testing solutions. At present, AIP has a complete set of motor testing solutions, including motor production line testing, laboratory motor testing; stator testing, rotor testing, motor testing; no-load testing, loading testing, etc. At present, AIP has reached friendly cooperation with many domestic and foreign group companies and actively cooperates with motor companies in product upgrading, technological transformation, industrial optimization, and other projects to achieve win-win cooperation.
There are several possible causes of fan motor failure:
■ Obstructed air flow causing the motor to overheat
■ Worn bearings or lack of lubrication causing motor noise or vibration
■ Damaged air blades or friction with the casing causing the motor to become less efficient
■ Damaged or short-circuited motor windings that prevent the motor from starting or stopping operation
■ Motor performance degradation due to rust or dust buildup on internal motor parts
There are several possible reasons for a fan motor to overheat:
Poor airflow due to clogged air filters or blocked air ducts
Motor power overload due to high fan speeds or excessive loads
Motor input voltage instability due to fan drive failure or improper parameterization
Increased motor friction due to lack of lubrication or severe wear of fan bearings
Sparks inside the motor due to aging or damage to the fan windings.
The function of a fan motor is to convert electrical energy into rotational mechanical energy, which in turn drives the fan impeller to generate airflow for air delivery and circulation.3 Fan motors can be categorized into alternating current (AC) and direct current (DC) depending on the type of input power source, with alternating current (AC) fan motors using alternating current (AC) as the input and direct current (DC) fan motors using direct current (DC) as the input.4 The fan motor can also be used to generate airflow, which in turn generates airflow.
The difference between a blower and a fan lies mainly in the direction and pressure of the airflow it produces.
Fan is a kind of equipment that compresses gas from low pressure to high pressure, the direction of airflow it produces is perpendicular to the direction of rotation of the impeller, and the pressure of the airflow it produces is higher, which is suitable for conveying high-density, low-flow, and high-lift gases, such as air conditioning, heating, and so on.
The fan is a kind of equipment that discharges gas from high pressure to low pressure, the direction of airflow it produces is parallel to the direction of rotation of the impeller, and the pressure of the airflow it produces is low, which is suitable for conveying low-density, high-flow and low-head gases, such as ventilating, cooling, and so on.
A fan motor is a device that drives the operation of a fan, which converts electrical energy into rotating mechanical energy, thus driving the fan impeller to produce compressed airflow. Fan motors can be categorized into the following types based on their structure and working principle:
■ Induction fan motors
■ Permanent magnet fan motors
