This post is a continue from the troubleshooting electric motors part 1.As I mentioned on my last post, I will share information and guideline about electric motors breakdown. Once it has determined that the motor is at fault, you can proceed to locate the problem with the motor. A troubleshooting guide outlines a comprehensive variety of motor [...]
The main purpose of motor enclosure is to provides protection from environment impacts such as rain,corrosive,rusty and many more in which motor installed. This protection can make motor more life span and can running in suitable condition.It also provide a types of cooling system for a motor depend on their types of enclosure. Before we select a [...]
Basically electrical motor have a phase to phase winding coil around armature to created a magnetic field.To avoid shortage between phase to phase winding,the insulation systems needed. It consists of the groundwall insulation and turn to turn insulation. Typically for induction motor insulation is the slot of paper to protect between cooper and ground surface.For [...]
D.C motor is the one of common application for industrial.It have several advantage compare with A.C motor.Dc motors applied for the momentarily deliver rated around three or more times from their torque. It also include with dynamic braking function or regenerative braking to obtained with dc motors for quick stops application.This function can avoid for [...]
Transformer rating or capacity depend on the limited of insulation temperature can stand for maximum load.The ratings can be up or down when we reducing a core and copper losses. To reduce core and cooper losses,we can improved the rate of heat exchange with proper cooling system or by improving quality transformer insulation that can [...]
The main component for electric motor is a stator.What is stator?Basically stators are wound with insulated windings made from cooper wire.The insulation materials for winding of stator such as polyester, poly vinyl formal,polyurethane etc. The main purpose of insulation is to protect the windings in the slots of the stator lamination and layer between winding [...]
This is a one from several types of transformer.It usually used for motor starter,we recognize it by name “auto transformer starter”.Basically design for auto transformer only have a single winding and provided with tap connection for step up or down. It have magnetic core with single winding which common primary and secondary circuits.The primary connection [...]
