It is zero at no load and one at standstill. Perform load test on 3-phase induction motor. Slip of induction motor The speed of induction motor must always be less than the synchronous speed and as the load increased the spree of the motor will decrease. 3). From these curves, it is clear that, beyond the point of maximum torque, the increased load on the motor results in a decrease in torque developed. Characteristic of Induction Motor ... For a single-phase induction motor, ... the number of rotation and the torque is as shown in (Fig. Where n slip = slip speed of the machine n sync Energy Conversion and Power Electronics Dr. Tim Hogan ... Cutaway view of a three-phase induction motor with a wound rotor and slip rings ... 6.3 Torque Development As the induction motor is located from no load to full load, its speed decreases hence slip increases. 2.40 shows the characteristics of induction motors. Torque Slip Characteristics - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Controlling the Torque-Speed Characteristics of a Polyphase Induction ... benefits of manipulating rotor currents in a slip-ring wound-rotor induction motor. ... the motor has an increased amount of torque Condition of Maximum Torque in three phase induction motor. 8.3 squirrel cage rotor. Induction Motor Torque Speed Characteristics. Three-Phase Induction Motor ... 3: Typical induction motor torque-speed curve. In this mode of operation, supply is given to the stator sides and the motor always rotates below the synchronous speed. The speed of the motor comes to zero, when the slip reaches to 1. ... UCF Induced Torque from Physical Standpoint (3) (a) (b) (c) (d) sin ... low slip region is pretty linear Principle of Working of 3-Phase Synchronous Motor. The slip varies from zero to one. The slip torque characteristic of an induction motor curves for various ranges of slip with different R2 are drawn. Fig. 0. b is called the slip. 4. The slip at which maximum torque occur ... IM Efficiency of Induction Motor Torque-Slip Characteristics 0. The torque ultimately depends on slip as explained earlier. Documents Similar To 3 phase induction motor speed control using PIC.pdf. The induction motor torque varies from zero to full load torque as the slip varies. To obtain Torque Slip characteristics of three phase induction motor. 5. load, motor has to produce more torque to satisfy load demand. Fig.3.6: Speed-Torque characteristics with variable stator voltage The salient features of stator voltage control method are: For low-slip motor, the speed range is very low. Fig. TYPICAL SPLIT-PHASE AC INDUCTION MOTOR The starting torque Torque and Power Characteristics . Any further more increase in load on the motor results in the slowing down of motor and it finally stops. Torque-Slip Characteristics in three phase induction motor. The difference between the speed of the stator and the actual speed of the rotor is known as the slip speed of induction motor. THREE-PHASE INDUCTION MOTOR March ... 3.
