(b) According to the Figures 1.2 and 1.3, it is assumed that the motors are run by 800-Hz and 1700-HZ power output from an inverter for OMM and Teco motors respectively. It is worth noting that with full-load speed (N) for both motors rotating at 47,888 rpm, answer the following questions (i) Determine synchronous speed (Ns), calculate the slip rate and compare them. (ii) Explain the efficiency of these two motors based on the power and the calculated slip rate.
