A three-phase AC induction motor is a constant-speed motor as a DC shunt motor. But the speed of the DC shunt motor can be changed smoothly simply using rheostats. This maintains the speed regulation and efficiency of the DC shunt…
Reading Induction Motor Nameplate sometimes very difficult and challenging because the nameplates Often get dirty, painted, and rusted as they get old. So reading motor information becomes frustrating. You will need motor information for installation of VFD, starter design, power…
Induction motor is mostly used motor in the industry as well as in domestic application because it’s a simple design, reliable operation, rugged construction, and simple control gear for starting, speed control, and three phase induction motor braking like plugging, dynamic…
There is a wide range of applications of induction motor in Industry as well as in daily life. because of its simple design, rugged construction, and reliable operation. induction motors have easy operation and simple maintenance, low initial cost, high…
VFD is a short form of a variable frequency drive also called Frequency converters, which has undergone extremely rapid changes, largely as a result of the development of microprocessor and semiconductor devices and their reduction in prices. However, the basic…
Why single-phase induction motor is not self-starting? Single-phase induction motor Starting winding to make self starting A single phase induction motor is very similar to a three phase squirrel cage induction motor except for single-phase motor, not self-starting.It has (i) a squirrel-cage rotor as to a…
Winding insulation resistance checking of three-phase / single phase Motor The motor is mostly used machine to drive loads in the industry, for pumping, elevators, and conveyor belts. so its reliability must be maintained, for the long life of the…
Types of insulation classes used in electrical motor/ transformer There are three main categories of insulating materials, gases, liquids, and solids. The types of insulating materials are classified mainly based on thermal capability. types of insulation classes for electric motors…
