As we known,the electric motor is the one of important equipment to drive the operation smoothly from beginning to end of product. Electricity cost normally around 60% came from electric motor running.It become more worth if installed motors are oversized,low efficiency,under design,poor maintenance or mismatched. So to know the actual motor performance, we need to determine [...]
Commonly method for power factor correction using the capacitor to generate reactive power ( kVAR ) to reduce apparent power ( kVA ) form inductive load. This time i want share a simple method to sizing our capacitor to improve power factor for induction motor and utility electricity.This method also can use for capacitor bank [...]
When install a motor using capacitor for starting or running methods,we must sizing the rated of capacitor suitable with motor to get correct starting torque and avoid winding from overheating and can cause a damage. This is basically a question of motor design.There is no straightforward regular relationship between capacitance and the motor size in [...]
Basic principles of operation Electromagnetic field generated from the stator does not rotate.It is a repeater between the poles as the poles alternating ac voltage changes polarity. The induced voltage in the rotor is the result of magnetic induction, and then the magnetic field produced around the rotor.This field is opposite to the stator field [...]
What is Miniature Circuit Breaker? MCB (Miniature Circuit Breaker ( BS 3871 ) is a mechanical device operate automatic operation designed to connect and disconnect the electrical circuit in the ordinary and extraordinary situation.Suitable for AC and DC voltage.It mean main function is to protected equipment or circuit from overload and short circuit. The size [...]
