“P” is short for the Related Value of BLDC Motor, which is mechanical power from shaft when BLDC Motor works in related condition.

A series of products, for the sake of manufacturing, motor’s power rate will increase progressively as per certain ratio. Smaller ratio, more varieties for customers, then smaller installed capacity and cost when used.

But due to the motors varieties is increasing, much more motor’s manufacturing equipments and more complex manufacturing management, then make the manufacturing cost to rise.

In conclusion, power levels should formulate according to manufacturing and applying. Increasing coefficient of BLDC Motor power is 1.35 in China.

At present, BLDC Motors’ power is small, if plan to design series products, whose increasing coefficient can be confirmed according to BLDC Motor’s increasing ratio, or factory’s manufacturing condition, or market needs.
