When a stepper motor has to generate a really big torque (higher than what it can deliver), it will stop moving, but the magnetic field continues to demand the motor shaft to spin. This can be heard as one or more “clicks” within the engine.
How to check if stepper motor is receiving current?
First of all, you must check that the motor receives electrical current. To do that, you don’t need a multimeter or any particular tool, just turn the printer on and try to move the motor s from the menu. On Marlin-type printers, select “ Prepare ” -> “ Move axis ” and select the axis ...
What happens when the extruder loses steps?
This produces a displacement of layers in the object, or sectors without deposited filament when the motor that loses steps is the extruder motor.
What does it mean when you can't move a motor?
If during the movement you can move the motor using your hand, it means that the magnetic field is not being generated within the motor, which is necessary for its operation. Since the field is generated by an electric current, it is most likely a power problem. Check the voltage supplied by the source with a multimeter.
How to move a Marlin printer?
On Marlin-type printers, select “ Prepare ” -> “ Move axis ” and select the axis of the motor that is not working. Order a sufficiently long movement, such as 150 mm in the X / Y axes, or 100 mm in the Z-axis. If during the movement you can move the motor using your hand, it means that the magnetic field is not being generated within the motor, which is necessary for its operation. Since the field is generated by an electric current, it is most likely a power problem.
What happens when the set speed is excessive?
The set speed is excessive: the acceleration required from the engine must be within its capabilities. When the motor fails to meet the demand for movement, it loses steps. The X / Y axes are the most affected by this problem.
How to control the direction of a stepper motor?
1. How to control the direction of stepper motor? Change the directional level signal of control system. Adjust the motor wiring to change direction, and the details are as follows: For two-phase stepper motors, only one phase of the motor wires is exchanged to connect the driver, such as exchanging A + and A-.
Why is it important to select a stepper motor?
Therefore, it is recommended to select the motor which has 30%-50% larger torque than the actual needs, because the stepper motor cannot rotate under overload, or causing losing step even if it overloads just one second. More seriously, the stalling or repeated and irregular motioning on the spot will be caused.
What happens to the output torque of a motor when it rotates at high velocity?
If the motor rotates at high velocity, the output torque of the motor will decrease. However, if the load requirement cannot be satisfied, stalling of motor will occur and whistler will be changed along with the change in frequency.
What happens to the phase current of a stepper motor when it rotates?
When the stepper motor rotates, the inductance of each phase winding of motor will form a reverse electromotive force. The higher the frequency is, the larger the reverse electromotive force is. Under its role, the phase current of motor is reduced with the increase in frequency rate (or velocity), thus the torque decreases. 5.
Why is the noise of the analog stepper motor driver large?
The noise of the analog stepper motor driver is large while it is basically no for the digital one, generally because one DSP chip is added to the digital driver to optimize the stepper motor drive. Therefore, to ensure the noise and vibration is as small as it is, it is advised to use the digital stepper driver.
What is the technical parameter for a stepper motor?
There is a technical parameter for the stepper motor: no-load start frequency. That is, the stepper motor can normally start pulse frequency under no-load. If the pulse frequency is higher than the value, the motor cannot normally start, and the stalling or self-locking may occur.
How to avoid crossing a motor drive line?

Why does opening a stepper motor cause a loss of torque?
Opening a stepper motor will result in a significant loss of torque due to a degradation in the magnetic strength. The motor will still work but will be weaker when reassembled.
What happens if you pull a rotor and touch a magnet?
If you pull the rotor and touch with the magnets a metallic (ferromagnetic) edge, then the field gradient in the gap is strong enough to 'reshuffle' the local magnetic domains.
Can you remagnetize a rotor?
A: Yes! Up to 60% magnetizing loss can be the result if the rotor is pulled apart. If all parts are replaced properly, the motor can be remagnetized at the factory, but the charge is substantial. If you have a motor failure, or are concerned about the performance, contact Anaheim Automation.
