Abstract :
The paper investigates the possibility to improve the efficiency of the squirrel cage induction motors. One analyzes the variation of the machines efficiency depending on the relative torque. The considered low voltage three-phase motors are the existing ones, having the rated power between 0.55 kW and 37 kW and the number of poles 4 and 6 respectively. The paper deals with “no tool cost” or “low tool cost” solutions. It is proposed a solution for the induction machine efficiency improvement, at full and partial-load regime.
