It’s pretty hard to break a stepper, so this is more likely a problem with the driver, the code, or the wiring of the driver. … Stepper motors are nearly unbreakable (in regular use). If you have them, try a different stepper, and try a different driver. I am using this driver.
How do you damage a stepper motor?
One real way you can damage a stepper motor is by taking it apart – never do this. It has something to do with the magnetic field in the motor being altered or weakened (or something) – it doesn’t make it stop working, but it doesn’t make the motor work better, either.
How long do stepper motors last?
The typical lifetime for a stepper motor is 10,000 operating hours. This approximates to 4.8 years; given the stepper motor operates one eight-hour shift per day. The lifetime of a stepper motor may vary in regards to user application and how rigorous the stepper motor is run.
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.
Can stepper motors run continuously?
Stepper motors fall somewhere in between a regular DC motor and a servo motor. They have the advantage that they can be positioned accurately, moved forward or backwards one ‘step’ at a time, but they can also rotate continuously.
Can you manually move a stepper motor?
So no, it only works one way. In the real world, manual movement of such a device is done with a “jog” switch to tell the program to move the stepper.
Is stalling a stepper motor Bad?
1 Answer. Stepper motors (depending on how they are driven) are generally always on. … So leaving the motor powered is not going to damage it. Now if there is too high of a load torque on the shaft – such as if you try and stop it spinning – the rotor will not be able to spin with the changing magnetic field.
Why do stepper motors fail?
One of the major problems with a stepper motor is complete motor failure. This problem is caused by excessive current being sent to the device by the power supply. A short circuit in the wiring from the power supply to the motor cause this problem with the stepper motor. Some application will cause this short circuit.
What is the maximum rpm of a stepper motor?
Modern stepper motors can reach rotation speeds of up to 1500 RPM, taking into consideration that the motor torque curve decreases considerably with the increasing of the step frequency.
How much does a stepper motor cost?

Does polarity matter on stepper motor?
To get the stepper just moving, polarity of each coil doesn’t matter, nor does it matter which coil is which. So make sure each pair of wires for a coil are together on one side of the plug (or the other side for the other coil), and plug it in.
How do you test a stepper motor with a battery?
Touch a small DC voltage (9V dry cell battery) Between either of the high resistance pairs, and the motor shaft will jump. Do the same to the other pair, the shaft will jump again. If so, the motors have passed the working test ;-)) Smile. Just leave the between coil, Middle wires hanging.
How much voltage does a stepper motor need?
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.
Can you control stepper motor speed?
In this example, a potentiometer (or other sensor) on analog input 0 is used to control the rotational speed of a stepper motor using the Arduino Stepper Library. The stepper is controlled by with digital pins 8, 9, 10, and 11 for either unipolar or bipolar motors.
How long can a motor run continuously?
You should anticipate, given proper attendance, that the motor can run continuously for the life of its brushes, which should be in the range of six months to a year. Presuming that the motor is too small to have its brushes changed by a trained electrician while running.
