Flow Chart For Design Of Induction Motor
Delivered to the shaft load flow through the stator winding.
Flow chart for design of induction motor. The characteristics of an induction motor the speed current starting torque maximum torque the motor losses and efficiency can all be determined from an analysis of the equivalent circuit. Power flow in an induction motor induction motor converts an electrical power supplies to it into mechanical power. In this paper assume the efficiency of an induction motor is 84 and power factor is 0 80. The various stages in this conversion is called power flow in an inductor motor.
Chronous motor speed is dictated by the line frequency of the supply voltage and the basic design of the motor. Power flow diagram and losses of induction motor power flow diagram of induction motor explains the input given to the motor the losses occurring and the output of the motor. Shown in for induction motors of fundamental frequency up to abstract this paper presents the parameters calculation of 5hp three phase induction motor the data obtained will assist to the fem designer to design the complete model of ac induction motor. For this reason and in the interest of keeping the magnetizing current as small as possible in order that the power component may be corre spondingly larger for a given rating the air gap of induction motors is made as small as mechanical clearance will allow.
2 60 hz 4 30 hz or 1800 rpm. The power flow diagram of an induction motor is shown below. 1 boldea k r and k x depend on the shape and size of the rotor slot the conductor material and the rotor current frequency. 2 line frequency number of motor poles for a four pole ac motor operating on 60 hz power the syn chronous motor speed is calculated as.
Diyoke okeke c uchechi aniagwu. Power flow diagram of 3 phase induction motor from different methods of speed control of three phase asynchronous motor g. In traditional designs of 60 hz line fed induction machines skin effect is represented by correction coefficients k r and k x for bar resistance and slot leakage inductance.
