Hi everyone,
I have this practical based independent learning project to do. It is on capacitor-start induction motors.
Background
A company uses 200 single phase induction motors for it production operations. The motors deliver a constant load torque of 0.8N-m while in operation. In order to increase production, the company wants to add in another 80 motors. However, there will be a current overload.
Assume that the current drawn by each motor initially is 2A each, if the current drawn by each motor is less than 1.5A, the current rating of the cables will not be compromised.
Power supply = 230V, 50 Hz.
I was thinking of adding capacitors in parallel to the main winding of the motor. However, how do i determine the value of the capacitor to be added?
S = 456VA
Pin = 273.378W
Pout = 120W
p.f. = 0.6
TIA
