Q: How are your motors packaged?

A: Our motors are carefully packaged in shock-absorbing foam. Each motor is placed in an individual pocket to ensure they remain protected and avoid any potential damage or vibration during transportation.

 

Q: What are the key advantages of NEMA 16 stepper motors?

A: Stepper motors offer several advantages, including high precision, low noise, low vibration, and high reliability. They can be controlled without the need for position feedback and provide cost-effective solutions for achieving precise control in various applications.

 

Q: Can NEMA 16 stepper motors experience step loss?

A: Step loss can occur in NEMA16 stepper motors under certain conditions. It typically happens when the applied torque surpasses the motor's capability, when the load becomes too demanding, or when the motor is not appropriately sized for the specific application. To mitigate the risk of step loss, it is crucial to manage torque effectively, consider the load requirements carefully, and select a stepper motor that is suitable for the intended application.

 

Q: Can we visit your factory before placing the order?

A: Yes, it’s our pleasure. And it would be helpful for us to set up a good relationship for business.
