A 3 kw series motor runs normally at 800 rpm on a 240 v, Ask an Expert

Engineering

A 3 kW series motor runs normally at 800 rpm on a 240 V supply, taking 16 A; the field coils are all connected in series. Estimate the speed and current taken by the motor if the coils are reconnected in two parallel groups of two in series. The load torque increases as the square of the speed. Assume that the flux is directly proportional to the current and ignore losses.
