FAQ

Q: How many square meters of your factory?

A: More than 10,000 square meters

 

Q: What is the relationship between step angle and resolution in a stepper motor?

A: The step angle is the angular displacement produced by each step of the motor. The resolution is determined by the number of steps per revolution. Resolution = 360° / Step angle.

 

Q: How do I select the right stepper motor for my application?

A: There are some factors that need to be considered, including torque requirements, operating voltage, step resolution, speed requirements, physical size limitations, and the type of driver/controller being used, etc.
