![]() The direction of rotation of this type of motor can be reversed by reversing the terminal connections of either the main or the auxiliary winding. 2: Typical torque-speed characteristic of a resistance split-phase motor Reversal of Rotation of Split Phase Motor The starting torque of this type of motor is generally 125 to 150 % of the full-load torque.įig. 2 shows the torque-speed characteristic of a resistance split-phase motor. Torque-Speed Characteristic of Split Phase Motorįig. Once the motor is started, the auxiliary winding is disconnected with the help of a centrifugal switch (S) at about 75 to 80% of the synchronous speed. The motor thus develops a starting torque. A rotating magnetic field is, therefore, produced (as in a two-phase motor). The resulting fluxes due to these currents are, therefore, displaced in space through 90 o and have considerable time phase difference. The resistance to reactance ratio of the auxiliary winding circuit being higher than the main winding, currents through them are nearly in quadrature (Fig. #Torque diagrams series#Instead of connecting externally such a high resistance in series with an auxiliary winding, its resistance may be increased by choosing a high resistance fine copper wire for winding purposes. The auxiliary winding along with the series resistor (R) is connected across the main winding. 1 : (a) Schematic representation of a split-phase type single-phase induction motor, (b) Connection diagram, (c) Phasor diagram If you get stuck do let us know in the comments section below and we will get back to you at the earliest.Fig. We hope this detailed article on Torque helps you in your preparation. A car with more hp than torque will always be quicker since this gives a car acceleration and speed. Start here to find parts for your Tuff Torq transmission. Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. Tuff Torq Hydrostatic Transmission Parts Diagrams
