3. Using the results of Procedure 7 and Table 4.9.4, make the following ratio calculations (use the 1.2 N.m [9 lbf.in] characteristics as the full load values). a) starting current to full load b) starting torque to full load torque c) full load current to no load comment 4. The squirrel cage motor induction motor is one of the most reliable machines used in industry. Explain The squirrel cage induction motor is the most reliable machine used in the industry because they are self starting in nature and economical. They are used in both fixed speed variable speed frequency drivers. 5. If the power line frequency was 50 Hz: a) at what speed would the motor run?
8. Do the following: a) Turn on the power supply and quickly measure E1, I1 and the developed starting torque. El=213.3/209.1 Vac, I1=4.087/3.702Aac, starting torque = 2.18/3.006 N.m [lbf. in] b) Calculate the apparent power to the motor at starting torque apparent power. apparent power 1507/1344VA - I, (amps) I₂ (amps) I, (amps) TORQUE (lbf-in) W₁₂ SPEED (r WT W (amps) (amps) min) LVSIM-EMS: 0.752 0.752 0.752 SIM SIM 0 DACI:0 0.703 0.679 0.68 -27 112 Table 1 Torque results at 0 lbf-in TORQU I, (amps) I, (amps) I, (amps) W₁ W₂ E (lbf-in) (amps) (amps) 0 0.752 0.752 0.752 SIM SIM 3 0.763 0.763 0.763 SIM SIM 0.848 0.848 0.848 SIM SIM 0.987 0.987 0.987 SIM SIM 1.115 1.116 1.115 SIM SIM 6 9 12 1773 1781 SPEED (r/min) 1773 1767 1738 1706 1676 (W₁+W₂) 100.1 84.58 W (Wi+W₂) 100.1 114.3 183.4 258.2 315.7
