- B: Abbreviation for stepper motor
- Y: Represents permanent magnet type
- J: Stands for geared configuration
- 48: Means 4-phase 8-step working mode
24BYJ48 Series Paramenters:

- Structural Features: Equipped with 24 magnetic poles and 48 teeth, the motor boasts a compact size, light weight, high resolution and excellent positioning accuracy.
- Electrical Parameters: Common rated voltages are 5V and 12V. For the 5V version, the typical coil resistance is 60Ω; for the 12V version, resistance values range from 200Ω to 300Ω. The step angle is 5.625°/64, and the insulation class is Grade E.
- Performance Advantages: The standard model (e.g., 24BYJ48-2002) delivers stable low-speed operation with low noise. The upgraded model (24BYJ48-S) offers higher resolution, improved precision and enhanced holding torque.
- Drive Mode: Adopts 1-2 phase excitation unipolar drive; the rotation angle and speed can be precisely controlled by adjusting pulse signals.
