Step motors are commonly used electric motors with high positioning accuracy, no feedback control required, and smooth torque characteristics. They are widely used in various industrial, commercial, and household equipment. In the process of using the step motor, losing steps is a common problem that needs attention to some details during selection, installation, and commissioning to avoid it.
1. Select Suitable Driver
Different types of motor drivers may provide different current and voltage values. Therefore, when selecting a motor driver, it is necessary to choose according to actual needs. If the current provided by the motor driver is too low, stepper motor losing steps is more likely to occur. Therefore, when selecting a motor driver, it is important to ensure that it can provide enough current and voltage to meet the torque and accuracy required for normal motor operation.
2. Set Reasonable Acceleration and Deceleration
In the control system, reasonable acceleration and deceleration need to be set. If the acceleration is too large or the deceleration is too fast, it will cause the motor to lose balance, vibrate or have losing steps. Therefore, the acceleration and deceleration should be increased or decreased gradually according to the specific motor model and mechanical load conditions to ensure normal motor operation.
3. Maintain Mechanical Load Balance
The mechanical load driven by the motor should be balanced as much as possible to prevent vibration or stepper motor losing steps caused by an imbalanced load. If an unbalanced load occurs, the mechanical device should be adjusted or repaired promptly to ensure normal motor operation.
4. Control Pulse Frequency
The frequency of control pulse should not be too high, and it should be set reasonably according to the specific motor model and mechanical load conditions. If the pulse frequency is too high, it is easy to cause the motor to lose balance and lead to losing steps. Therefore, the frequency of control pulse should be set according to actual needs.
5. Check Connections and Ensure Firmness
Regularly check whether the connections of the motor and sensor are firm to prevent losing steps caused by poor contact. At the same time, when installing the stepper motor, ensure that it is installed vertically to avoid unnecessary force on the motor.
In summary, if we pay attention to the above details, we can effectively avoid losing steps of the step motor. When using a step motor, reasonable control should be carried out according to the specific conditions to ensure normal motor operation.
