Abstract
Electric saw being powered by an external power supply through a multicore cable. The multicore cable includes electrical wires for supplying power to the motors of the electric saw and communication wires for data communication between the electric saw and the power supply. Two motors of the electric saw are three phase permanent magnet motors, with an outer rotor and an inner stator. Each of the two motors has three Hall Effect sensors located around the outer rotor.
