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…
VFD block diagram showing rectifier , intermediate circuit and inverter
The star and delta connections are two common types of connections used in the winding of three-phase motor. For star connection or delta connection of winding, six wires or leads of the motor winding must be accessible. 3-phase motors are…
A Slip Ring Induction Motor is a type of asynchronous induction motor. Slip ring induction motors rotor is wound identically to the stator and is connected through rotating electrical contacts known as slip rings. These slip rings let the induction…
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…
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…
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…
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…
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…
Due to the desirable Torque-speed characteristics, the series motor is exclusively used in traction applications. Dc series motor satisfy all requirements for this kind of work and services but the transmission of ac power is more economical than DC. This…
