Features:

• Precision: This motor has a precise 1.8° step angle, making it suitable for applications requiring fine, repeatable control without the need for feedback mechanisms.
• Torque: With a maximum torque of 1.26Nm (12.8 kg.cm), it offers substantial torque for medium-scale CNC applications.
• Standardized: The motor conforms to the NEMA 23 standard, allowing for easy interchangeability with other motors in the same class.
• Common Applications: It's ideal for CNC routers, milling machines, 3D printers, and similar machinery where high precision and torque are required.

Driver Options:

• H-Bridge Drivers: For those who prefer building their own control circuitry, an H-bridge driver can be used, requiring a state machine for step control.
• Dedicated Stepper Drivers: Easier to use, such as the THB6064AH or DM542T, which have internal state machines, reducing the load on your microcontroller and simplifying software development.
