Everyone knows that negative pressure fan is the ventilation and cooling equipment of many livestock farms, and its core component is the motor. Normal brand of negative pressure fan motor has a motor brand name, which indicates the voltage, power, motor grade, speed, current value and other parameters, these parameters are the performance attributes of the motor, but also the identity card of the motor. But how can ordinary consumers understand the motor parameters on the negative pressure fan? Why can't they use them without motor parameters?

What parameters?

1.Motor power

The motor power marked on the negative pressure fan is generally expressed in kilowatt-hour (KW) units. If it is 1.1 kilowatt, it represents 1.1 degree of power consumption per hour. Consumers can calculate the line load, power consumption and electricity expenditure when they see the power on the negative pressure fan motor.

2.Motor voltage

There is a voltage parameter on the sign of the negative pressure fan motor. If the value is 380 volts, it means that the power supply is three 380 volts of industrial power. If the value is 220 volts, it means that the power supply is 220 volts of lighting power. Never connect the power supply incorrectly, otherwise the motor will burn up, or even burn up the whole circuit.

3.Motor speed

The motor speed of the negative pressure fan represents the number of times the motor rotates on its idle load per hour axis. This parameter is related to the number of times the fan blades rotate. The biggest relationship with consumers is that the higher the speed, the greater the noise of the negative pressure fan motor. The lower the speed of the negative pressure fan motor, the smaller the noise generated by the negative pressure fan in use time. Many negative pressure fans in order to reduce the noise. It will reduce the speed of the motor by changing the size of the pulley.

4.Motor brand

The brand on the motor sign represents the motor manufacturer. Users can find the motor manufacturer through the brand, and can also identify the quality of the motor according to the brand. Once the motor causes safety accidents, the manufacturer can also be held accountable by the brand.

5.Protection class

The motor protection grade indicated on the motor sign represents the insulation grade and waterproof grade of the motor. The higher the general protection grade, the higher the resistance to high temperature of the negative pressure fan motor, the longer the continuous operation time and the better the anti-rainwater splash. On the contrary, the lower the protection grade of the motor, the worse the insulation, the higher the resistance to high temperature at the end of the month, the shorter the service life of the motor than that of the protection grade. 

Notes: No sign or motor parameters on the negative pressure fan motor means that it is not manufactured by a regular manufacturer. Once problems occur, the loss is painful, so it can not be used.

NOSCH MOTOR is a trusted brand of the public, which occupies an important position in this competitive market environment. What is indispensable is that the excellent quality of the product itself has been recognized by customers. It is the most sensible choice to choose NOSCH MOTOR
