What is the step in the step motor
Stepper motor has a technical parameters: no-load start frequency, the stepper motor under no-load condition can normal boot pulse frequency, if the pulse frequency is higher than the value, the motor does not start properly, may be lost or blocked. In the case of load, the start frequency should be lower. If you want to make the motor to achieve high-speed rotation, the pulse frequency should be to accelerate the process, namely the start frequency is low, and then in a certain high frequency acceleration to want (motor speed from low speed to high speed).
3: the auxiliary power source is not suitable, and the auxiliary power supply should be 1.5-2 times the rated power supply of the driver, which is more serious than the imaginary mark The control part should be excluded from interference, away from the frequency converter, antistatic. The equipment can be ground to ground processing, prevent the inductive power, the signal line is done to block processing, set up the proper start frequency, and do well to add deceleration
Analysis of stepping and missing steps of stepping motor: Step 1: in the wrong type of motor, the inertia of the motor moment is not enough, or the inertia of the motion of the object exceeds the self-locking force of the motor, causing the lost step or the lost step 2: drive improper selection, form a complete set of drive current is small, affect the normal operation of motor, now on the market a lot of drive current virtual target, take a peak current when the rated current to fool consumers, drive type rated current should be greater than stepper motor 1.2 1.5 times rated current
