Flour machinery no-load current big reason is what

Flour Machinery during no-load current is very big, this is the problem of the motor, one is a part of the coil with local short circuit phenomenon, another reason is winding and the way of parallel the number of turns.

If no load current is big, but the no-load loss is normal, because the flour machinery motor air gap is too big or magnetic circuit saturation; If the no-load current, no-load loss is big, shows that the iron loss of the motor is larger.

If no load current and no-load loss are large, but the stator winding dc resistance. This may be a core quality does not meet the requirements, the stator and the rotor iron core has assembly does not reach the designated position and is not aligned, or is not in conformity with the positioning size.

No-load current no-load loss in normal but the reason is the difference in the quality of silicon steel sheet; Core length is insufficient or overlying false finite length is insufficient; Small flour machinery fault with big fan or more fan blades; Due to improper assembly rotor in irons or poor quality of bearing, bearing inner add too much grease on the mechanical consumption is too large.

To avoid flour machinery the phenomenon of no-load current is big, have to check equipment, find out the cause of the time this happens, suit the remedy to the case.
