Pulse Motor – Just a coil
The ultimate result of stripping out components… just a coil is left to spin the rotor around. It was realised that A/C line ripple was within the power supplied from the wall adapter, even after fitting a FWBR and a capacitor (the cap being too small). This, however, gave the thought that the 50Hz A/C cycle was being used by the coil as a match with rotor speed. When spun correctly, the rotor spins.
