Vibration motor power calculation

Vibration motor power calculation :
Motor power , should be based on the required power production machinery to choose, as the motor at nominal load . Selection coal vibrating screen should pay attention to the following points:
① If the motor power selected too small . There will be " small horse cart " phenomenon , resulting in long-term motor overload . Insulate due to heat damage. Even the motor is

burned.
② If the motor power selected too China Vibrating Screen large . There will be " big horse car " phenomenon. The output mechanical power can not be fully utilized , power factor and efficiency is not

high , not only for users and grid disadvantage. But can also cause energy waste .
To correctly select the motor power , you must go through the following calculation or comparison:
P = F * V / 1000 (P = computing power KW, F = desired tension N, working machine line speed M / S)
For constant load continuous work, can be calculated as the required motor power :
P1 (kw): P = P/n1n2
Where n1 is the production efficiency of the machine ; n2 efficiency of the motor , the transmission efficiency .
Power obtained by the above formula P1, is not necessarily the same power with the product . Therefore . The rated power of the motor selected to be equal to or slightly greater

than the calculated power .
In addition . The most commonly used is the analogy to select the motor power . The so-called analogy . With similar production machinery is used to compare the motor power .
Specifically: the understanding of the unit or other units of similar nearby production machinery using multiple high-power motor , and then use the power of the motor is

similar to trial . The purpose is to verify that the selected test motor and production machinery match.
