Stepper motors , Motor Drivers Technologies: Full-Step, Half-Step, and Microstep Control Modes
Advantages and Disadvantages of Three Modes (Full-Step, Half-Step, Microstep)
| Control Mode | Advantages | Disadvantages | picture |
|---|---|---|---|
| Full-Step Mode | 1. Precise step angle and speed control, suitable for conventional scenarios. 2. High holding torque to meet large static torque requirements 3. High torque output at high speeds, beneficial for high-speed operation. | 1. Large step angle causes obvious positional jumps and insufficient positioning accuracy. 2. Prone to resonance, leading to overshoot, torque reduction, vibration, and noise. | |
| Half-Step Mode | 1. Improved positional resolution and higher accuracy than full-step. 2. Alleviates overshoot, vibration, and noise issues in full-step mode. 3. Slightly increased torque at low speeds, suitable for low-speed loading. | Rotation is not completely smooth, especially with prominent instability at low speeds, failing to meet high-precision smoothness requirements. | |
| Microstep Mode | 1. Extremely high positional resolution for fine-grained position control. 2. Smooth operation with significantly reduced vibration and noise, offering stability and reliability. 3. Wide application in various high-precision and low-noise fields. | 1. Actual accuracy is affected by motor structure, load, current precision, etc. 2. Incremental torque decreases when stopping at microstep positions. |
