micro electric motor

The power of the micro reduction motor should be selected based on the required power of the product, and the micro motor should be operated at rated load as much as possible. When selecting, the following two points should be noted:1.If the power of the micro motor is selected too low, it will cause long-term overload of the micro motor, causing insulation damage due to heating, and even the micro motor to be burned;2.If the power of a micro DC motor is selected too high, its output mechanical power cannot be fully utilized, and the power factor and efficiency are not high, resulting in waste of electrical energyWhen selecting a micro reduction motor for different products, it is necessary to correctly select the power of the micro motor through the following calculations or comparisons:For constant load continuous operation mode, if the power Pl (kw) of the load is known, the required power P (kw) of the micro motor can be calculated as follows:P=Pl/nln2, whereNl is the efficiency of the product;N2 is the efficiency of the micro motor (i.e. transmission efficiency).The power calculated according to the above equation may not necessarily be the same as the product power. Therefore, the rated power of the selected micro motor should be equal to or slightly lower thanGreater than the calculated power.Compared with continuous rated micro motors with the same power, short time rated micro motors should be selected as much as possible when conditions permit. For micro DC reduction motors with intermittent working quotas, the power selection should be based on the size of the load duration, and micro motors specifically designed for intermittent operation should be selected.
