As we know,motors is a common used for rotating equipment to make domestic and industrial operation more easier.In general,electric motor is reliable machine with minor maintenance require.But to ensure electric motors have a more life span and service life,we must perform periodical inspection and service and schedule it with proper arrangement. With periodical inspection and [...]
How many second we need to setting for changeover timer from STAR to DELTA sequence for Star Delta Starter?This question is very popular among electrician around the world when handling the Star Delta Starter for their application. From my experience,honestly,it quite difficult to get the accurate times for star delta changeover.But we can get the approximate times [...]
The main purpose of this 16 steps is to look at the systematic and proper work sequence on disconnecting the wiring,check the motor nameplate, specification when replacing the motor until complete the task. I would like to share my routine standard procedure for replacing a new motor.I created this procedure follow the safety guideline and reference from [...]
As we know,motor protection is one of the important criteria when we involve for AC motor installation,wiring and termination works.Commonly magnetic contactor,fuse, Molded case circuit breaker (MCCB) and overload relays are used for motor control device of induction motor. In general ideal for motor protection,it have two basic protections always installed for every motor are Over-load protection and Short-circuit protection.For [...]
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 [...]
Soft Starter is the common application for electric motor control driven for industry.It efficient motor control and the application is user friendly. Soft starter now more advance technologies and can replaced conventional motor starter such as star delta starter,auto transformer or Direct Online starter.It already built in the motor control system and easy to install [...]
Braking application for electric motor are used widely around the world for equipment or machinery such as electric crane,barrel machine,electrical train,lift or for industrial drive. Basically the braking system for electric motor fundamental is a one mechanism to created retarding torque to stop the motor rotation with sudden or slow stop depend on application system. [...]
