A small tip:

Here are some of the key features of Frankhuai’s NEMA 23 motor with brake and encoder:

• Precise control: Servo motors can be controlled to rotate their shaft to a specific angle with high accuracy.
  Position feedback: Servo motors use a feedback loop mechanism to ensure that the shaft reaches the desired position.
  Holding torque: Servo motors can hold their position even when external forces are applied.
  Compact size: Servo motors are available in a variety of sizes, from very small to quite large.
  Relatively low cost: Servo motors are generally more affordable than other types of motors that offer similar precision control.
