The functionality of an electric motor is treated at this video. The motor is converted from a stepper motor into an electronically commutated motor in progress of the film. In addition, the efficiency of the motor is determined. To do so, the electric input power and the mechanical output power are measured. The used materials …

Joule Thief with Low RPM Stepper Motor Generates Usable Electricity
visit madscientisthut.com for full details on the circuit. In this short video a stepper motor has both coils connected to two bridge rectifiers feeding a 8200uF 10VDC capacitor. The capacitor then feeds a Joule Thief circuit that is running 4 white LEDs in series. The generator is able to light the LEDs (14VDC) at very …

EL Inverter using Stepper motor
This is an experimental EL inverter for 2×3 EL Panel, using Stepper motor. With the simple set-up, I got around 120VAC @ 4.4KHz. The Stepper motor was driven by a spiral saw running at 15000 rpm. Different Stepper motors would yield different outputs so extra care should be taken when handling high voltage output. Do …
