motor nameplate information #6 – Construction

15/03/2011 by 1 Comment

This information is very useful when we selected the electric motor.From this data we can estimate the type of motor and the suitable application to ensure it running full capacity and more efficiency.

This is a basic data that we can get from electric motor name plate.Normally it tell about enclosure,motor frame,and bearing.This information can make we easier to rectify any problem when motor is defected.

Example we can know the size and type of bearing used for that motor.We can know the information without dismantle the motor.Only from the nameplate of motor. read more

Motor Capacitor Run

30/09/2010 by Leave a Comment

Motor capacitor run basic operation is same with motor capacitor start that use a capacitor to generate the current pulse and create the electromagnetic field for the winding to push a rotor to turn around.

Normally capacitor for this motor made from polypropylene film capacitors  material and it can running continuous without any problem.Run capacitor rated from 2 μf until 100 μf with nominal single phase voltage 110 VAC,240 VAC and 440 VAC.

If we installed the capacitor with wrong wiring termination,it’s can’t generated the electromagnetic field and motor not running.We can recognize this symptom if motor create a noising sound and it’s can make a motor drop the performance and more serious can cause the winding damage.   read more
