In addition to the requirements of performance parameters, small and medium-sized centrifugal fans often have some basic requirements for the motor.
It mainly includes the following aspects:
The terminal box adopts split type and can be connected at the bottom and top. The Junction Box is located on the right side of the centrifugal fan distribution motor.
Communicate. Asynchronous. Air-cooled motor, motor insulation class F, temperature rise to Class B, Protection Class IP54.5. The supply voltage is 380V +/-10,50Hz. Under design conditions, the rated output of the motor shall not be less than 120 as required by the driven equipment.
When the frequency changes to ± 5.5. When the voltage changes ± 10, the motor can work normally without damage. At rated voltage, motor starting current shall not exceed 650 of rated current.
The multi-phase motor marks the phase sequence on the nameplate on the junction box, and marks the direction of rotation with an arrow. Motor design. Manufacturing. Performance conforms to Chinese or IEC standards.
Four. The centrifugal fan distribution motor is provided with lifting lugs or lifting rings according to the standard. The motor is provided with a grounding device.
