Experiment on stepper motor(A)

Stepper motors are usually of microprocessors or custom controller ICs, and power is often controlled by circuits lit stepper motor driver and power transistors. Precise movement is possible, but the complexity usually land stepper amateur in the “maybe someday” bin parts. But stepper can be used for a variety of applications without complex circuitry or programming. At first glance, the stepper motor a bit intimidating, as at least four sons and often are, six years ago. Most steppers have two coils, and some are even operated the center, where four or six son. Quick checks can ohmmeter to determine which son to go together and tap the center to be identified by measuring the resistance between the son, the center-tap to half of the total liquidation of the resistance against the two ends of the coil action. Bring son to go together in a knot and tie a knot in the wire center-tap for easy identification later. Stepper motors have become quite frequent and in all shapes and sizes from many dealers surplus. Investigators can also be accessed Stepper good old office and computer equipment.
Steppers are excellent generators of low power and surprisingly efficient motors for low power applications at low speeds. As a starting point, try to connect the windings of two steppers with each other. Select Stepper rotates freely so that the internal friction does not spoil the experience. When you rotate a drive shaft, it will follow another. Certainly, there is little torque. But it shows that steppers are used to produce electricity.
