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 [...]
When we need to evaluate the motor condition,HI-POT tester or High Potential tester is the common equipment are used.As we know,a multimeter or ohm meter reading only can determine if a motor winding is open or shorted but cannot checked winding insulation condition if shorted with ground or phase. The main purpose of the Hi [...]
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 [...]
On my last post, I’m already explained about braking system for electric motor.It about a introduction for braking system for electric motor. This time i want share some information about two common method that used around the world for braking electric motor for any application,equipment or machinery system. For this two method for braking electric [...]
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. [...]
If we take a look at electric motor nameplate,we can see the several important information and specification about electric motor.This time i want explain about dual voltage for power supply. It is like a simple thing and not so important BUT if we make a mistake about electric motor voltage power supply,it can cause the [...]
Electric motor generated the heat from inductance process.So the temperature is important factor to ensure the electric motor can operated smoothly without any problem. Heat can effected the efficiency of motor,maximum load capacity,duty cycle and winding lifespan.That why heat from motor operation must be controlled by motor cooling. How to control temperature for electric motor?The [...]
