How to choose the variable frequency motor will not make mistakes

I believe that everyone is no stranger to the use of variable frequency motor, in order to ensure that everything goes smoothly when we work, we should pay attention to some problems when choosing the motor, otherwise it will be too late to regret, how should we choose when choosing? Let's take a look at the introduction of Xiaobian.

1. Type selection

Choose which kind of motor type of our factory, on the one hand, according to the requirements of consumer machinery on the mechanical characteristics of the motor, starter energy, 

speed regulation performance, braking system, overload ability and so on; In addition, on the one hand, it is also necessary to reduce the initial investment, reduce operating expenses 

and other economic aspects of comprehensive differentiation. Under the condition that there is no extraordinary request for performance such as starting and reading speed, the 

three-phase asynchronous cage motor is preferred.

2. Power selection

When selecting the tilting power of the motor, the selected extra power of the motor should be greater than the power required by the consumer machinery. Can not overload. Can not 

be long light load. Can use analogy method, statistical method, test method, calculation method, etc.

3. Selection of voltage

The extra voltage of the switching motor should be selected and the voltage difference of the supply network. Well separate motor set power thinking. The additional voltage of the DC 

motor must also be matched with the supply voltage, often operating 110 V or 220 V. High power DC motor can be advanced to 600-800 V total

4. Selection of speed

According to the speed and transmission of consumer machinery. After economic and technical control must be the extra speed of the motor. The higher the extra speed of the motor 

with the same extra power, the lower the motor volume, the heavier the summer and the lower the cost, the problem of how to choose the popular flywheel torque inverter motor has 

been introduced to you in detail in the above article, we must pay attention to these aspects when choosing, so that this error will not occur in the later work.
