What are the characteristics of the outer rotor fan? What are the advantages and disadvantages? How to speed? Let's take a look at the relevant content.

The external rotor fan is of reverse structure, the stator is in the middle of the motor, and the rotor is outside the motor. The outer rotor fan adopts the advanced structure and reasonable aerodynamic design of the outer rotor motor directly driving the impeller. It has the characteristics of high efficiency, low noise, light weight, compact structure, and convenient installation and maintenance. The rotor name and blades rotate outside the stator, with compact structure, space saving and exquisite design. The motor is installed in the middle of the impeller, which has a great cooling effect on the motor itself. The starting current of the outer rotor fan is small, and the protection level of the motor can reach IP54. The ambient temperature is between -30 and 6. Uses: air heater, heat pump, condenser, cooling device, evaporator, electronic equipment, air supply or heat dissipation, etc. It has the characteristics of compact structure, convenient installation, reliable operation, low noise and energy saving.

External rotor fans are widely used in hotels, restaurants, industrial and mining enterprises, office buildings and other building facilities, as refrigerators, cold storage or auxiliary equipment for ventilation and heat dissipation (such as with supermarket cold storage, ice machines, air coolers, chillers, condensing units and other refrigeration equipment or facilities supporting the use. And dehumidifier, evaporator, side wall fan, fire fan, air conditioning fan and other equipment supporting the use.

The external rotor fan is a new type of fan which is different from the general traditional motor. Its motor is the stator in the middle of the motor, and the rotor is outside the motor, which is the opposite of the traditional one. The outer rotor fan adopts advanced structure and reasonable aerodynamic design to directly drive the impeller, which is more convenient to use. Next, let's take a look at some manufacturers' price recommendations for external rotor fans, as well as their advantages and disadvantages and speed control methods.

Advantages and disadvantages of external rotor fan and speed control method:

Disadvantages: Compared with the inner rotor fan, the outer rotor fan can be made more compact, suitable for small boxes or places with limited structure. The efficiency of the outer rotor motor is relatively low, and the speed is slightly lower under the same number of poles and the same power.

Advantages: The inner rotor fan has low torque and high speed. Generally, vehicle models (such as cars, boats, helicopters) are used. The outer rotor fan has better heat dissipation. If the internal rotating motor burns out, it is difficult to repair, because the enameled wire cannot be wound by itself, and the external rotor fan can be repaired by itself.

External rotor fans are generally widely used in transmission belts. For example, the transmission belt in the dock and power plant is used as a motor, which is fixed at one end of the belt and acts as a power and pulley. There is a special outer rotor fan governor to control its speed.
