YWF 120-400 Three-Phase AC Permanent Magnet Synchronous Internal Rotor Motor

Compared with the external rotor fan,the air volume of the YWF 120-400 three-phase AC permanent magnet synchronous internal rotor motor can be very large. The fan impeller of the three-phase AC permanent magnet synchronous internal rotor motor flow fan rotates with the motor spindle, and the motor base is fixed. Because of the simple structure of the inner rotor axial flow fan, the cost is usually relatively low, and it is suitable for occasions with strict requirements on cost. The three-phase AC permanent magnet synchronous internal rotor motor may have higher speed and less torque in some cases(such as vehicle models), which is suitable for specific application scenarios. In most cases, external rotor fans are considered the better choice due to their higher airflow efficiency, lower noise levels, and better energy efficiency performance. However, this does not mean that the three-phase AC permanent magnet synchronous internal rotor motor does not have its application value, in some occasions with strict requirements on cost or specific application scenarios(such as transportation vehicle models), the three-phase AC permanent magnet synchronous internal rotor motor may be more advantageous. The specific choice of which type of fan, but also need to be based on the actual application scenario, cost budget performance requirements and other factors for comprehensive consideration, welcome to come to consult.
