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. The choice of the type of our factory motor type, on the one hand, according to the requirements of consumer machinery for the mechanical characteristics of the motor, starter energy, speed regulation performance, braking preparation, overload ability, etc.; 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.

Power selection When selecting the power of the motor, the sel
