FAQ
Q: What is step resolution in a stepper motor?
A: Step resolution refers to the number of steps per rotation or movement that a stepper motor is capable of making. Common step resolutions include 1.8 degrees or 200 steps, but other resolutions are also available.
Q: Considering the transportation duration, how do you ensure the motors remain undamaged?
A: To ensure the motors remain protected during transportation, we take precautions by securely packaging each motor using shock-absorbing foam. We individually encase each motor in a pocket to safeguard against potential damage caused by vibrations or impact during transportation.
Q: Are there any safety considerations when using stepper motors?
A: Yes, there are several safety considerations when using stepper motors:
1. Proper Electrical Wiring and Grounding: Ensure that the electrical connections between the stepper motor, driver, and power supply are secure and properly insulated to prevent electrical hazards.
2. Heat Dissipation: Stepper motors can generate heat during operation. Adequate cooling measures, such as heat sinks or cooling fans, should be in place to prevent overheating.
3. Mechanical Hazards: Take precautions to avoid any mechanical hazards, such as pinch points or entanglement with moving parts, especially when dealing with high-speed or heavy-load applications.
