The experimental power draw was acquired from current measurement in the electric motor in several charging cycles of the gyratory crusher, operating at ω = 150 rpm and o s s = 240 mm. Consequently, the mean no-load power is 443 kW, and the mean crushing power is 1329.4 kW.

In Delta Connection, the total Power of three phases could be found by: P = √3 × V L × I L × CosФ … Or; P = 3 x V PH x I PH x CosФ; P = 3 × V × I; The speeds of Star connected motors are slower as they receive 1/√3 voltage. The speeds of Delta connected motors are high because each phase gets the total of line voltage.
