How can a stepper motor operate without a microcontroller?
Can you use a stepper motor without a driver? In this instructable, i will teach you how to run a stepper motor continuously at high speed without a driver circuit or arduino or AC power supply.
Also, by interchanging the wirings, you can run it in both clock-wise & counter clock-wise directions.
This method is applicable for 6-wire stepper motor.
What is needed to run a stepper motor? Here is a list of recommended items needed to follow along:
EasyDriver Stepper Motor Driver.
Small Stepper Motor.
Breadboard.
Male-to-male Jumper Wires.
Male Break Away Headers – Straight.
Arduino Uno (or similar microcontroller)
Soldering iron and accessories.

Can you turn a stepper motor by hand?
No, it won’t cause any damage, at least in non-pathological cases where you’re not exceeding some shaft or drive train mechanical limits and are applying a torque directly to the stepper shaft.
How long can a stepper motor run?
For a more professional stepper motor with sealed ball bearings and no gearbox you might typically get 500k+ hr MTBF, and units such as this can get 1M hr MTBF.
However these Nema 8 sized units are significantly heavier weighing in at perhaps 0.

What voltage is my stepper motor?
Stepper motors have a rated voltage and current. A typical stepper motor like our NEMA 17 might have a rated voltage of 2.8 Volts and a maximum current of 1.68 Amps. This basically means if you hook it up to 2.8 Volts it will draw 1.68 Amps.
Is stepper motor stronger than DC motor?
Stepper motors provide their maximum torque at low speeds, which makes them especially useful in high precision, holding applications such as robotics and 3D printers. The main difference is that, while stepper motors can push harder from rest, DC motors tend to have more sustained output.
Do you need an encoder with a stepper motor?
Stepper motors have remarkable stopping accuracy, and accurate control with open-loop is possible.
The structure of the stepper motor, which requires no encoder, allows for the simple drive system and low cost.
How is stepper motor speed controlled?
A gearbox utilizes gear ratios to step down and up rotational speed and torque. A third method for stepper motor speed control is voltage regulation. By utilizing an LM555 timer, the current supplied will become a square wave. The “high” time of the signal will be when the rotor rotates.
Are stepper motors AC or DC?
Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.

Do stepper motors hold their position?
This means that when the windings are energized but the rotor is stationary, the motor can hold the load in place.
But a stepper motor can also hold a load in place when there is no current applied to the windings (for example, in a power-off condition).
This is commonly known as the detent torque or residual torque.
Do stepper motors wear out?
Since a stepper motor has no brushes to wear out, its life usually far exceeds that of other mechanical components in a system. If a stepper does fail there are certain components which are likely to be involved.
How do I know if my stepper motor is bad?
Most inexpensive motors use glue to hold the shaft to the rotor, and most quality steppers will use grooving along with adhesive. To test the motor, first use an ohmmeter. It will indicate if a winding is burnt up and what type of step motor you have, usually a bipolar or unipolar.
Why isn’t my stepper motor is not working?
Most Stepper drivers have a range of voltage that they can operate within. Disconnect the power supply from your project, make sure that the voltage is set to the right amount, turn it off, and ‘then’, connect it to your project. That way you are sure not to feed to much voltage when you turn on your power supply.
