How to make a stepper motor turn only one direction?
While keeping the LEDs plugged in, I reconnected the motor one wire at a time, and the pulses kept coming in order until I plugged in the fourth wire of the motor. Then, the pulses for the ‘reverse’ direction seemed to be stalled, while still coming out alright for the ‘forward’ direction.
How does error accumulate in a stepper motor?
The remarkable feature of steps motors, though, is that this error does not accumulate from step to step. When a standard stepper motor travels one step it will go 1.8° ± 0.05°. If the same motor travels one million steps, it will travel 1,800,000° ± 0.05°. The error does not accumulate. Stepper motors can respond and accelerate quickly.
What is the accuracy of an oriental stepper motor?
ORIENTAL MOTOR’s standard stepper motors have an accuracy of ± 3 arc minutes (0.05°). The remarkable feature of steps motors, though, is that this error does not accumulate from step to step. When a standard stepper motor travels one step it will go 1.8° ± 0.05°. If the same motor travels one million steps, it will travel 1,800,000° ± 0.05°.
How many phases are there in a stepper motor?
The opposing pair of poles constitutes one phase. Since there are 10 magnetic poles, or five phases, in this particular motor called a 5-phase stepper motor. There are 50 teeth on the outer perimeter of each rotor, with the teeth of rotor cup 1 and rotor cup 2 being mechanically offset from each other by half a tooth pitch.
How is the rotation of a stepper motor controlled?
Not only does a stepper motor convert electrical power into rotation, but it can be very accurately controlled in terms of how far it will rotate and how fast. Stepper motors are so named because each pulse of electricity turns the motor one step. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn.

Why does my stepper only turn in one direction?
It has to be the driver. As long as the stepper is NOT connected to the output, the stepping signals come out fine. If I connect the wires one by one, the signals still come out fine. But, as soon as I plug in the 4th wire of the stepper, it goes haywire.
