Hi,

This post I would like to share video how to disconnect or dis-engage THOMAS Coupling from motor hub during maintenance works.In this video,technician plan to replace new bearing for the motor due to abnormal sound detected from bearing.Normally in industry or chemical plant,Thomas Coupling is the one of common application to connect electric motor as a drive and pump as a rotary equipment for the process.

The main reason why Thomas coupling are used :-

  1. To transmit power from one shaft to another, efficiently and effectively.
  2. To accommodate slight shaft misalignment which develop in service.

Thomas coupling application also can protect our equipment from mechanical damage and misalignment. Below several protection when using Thomas coupling :-

1. Absorb shock, vibration and pulsations.

2. Decrease cross load on bearings.

3. Accept load reversals.

4. Minimize backlash. Read More

Motor start and run capacitor

21/03/2011 by 6 Comments

Application of start and run capacitor for single phase motor.

Why we applied a capacitor for single phase induction motor?The reason is to improve performance of motor by generate the rotating field.Design for this motor have a two ( 2 ) stator winding,and one of it is the auxiliary and is connected by a suitable capacitor size.

The capacitor increases the starting torque and the full load power as the current flowing through the auxiliary winding, de-phased by the capacitor, creates a rotating field.The voltage across capacitor usually higher than the mains supply.

The choice of the capacitance is usually empirically made on the motor. This is because of shuttle differences between motor manufacturers.As the torque and the power of the motor also depends on the reactive power of the capacitor. read more
