What is the reason for the stepper motor not running at high speed
The average step motor speed is not high, 3, 000, the main reason for losing the step is to tell the torque is not enough, or the pulse has a problem
What is the high speed specified? Stepper motor is a low speed high torque motor, the majority of applications in 600 ~ 1500 RPM range, provide equipment load is very light, to run high-speed, need to refer to the stepper motor torque of the condition of different voltage and frequency curve, if the device in high speed work need is smaller than the motor output torque, torque can work, otherwise the motor will be closed. Welcome to the technical support department of innast.
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 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
What is the reason for the stepper motor not running at high speed? If the voltage and current under the condition of normal appear this kind of circumstance, should problems arise in the driver, because the phenomenon of out-of-step is usually appear in the frequency of the driving is beyond the scope of the motor itself a set! In order to do this, the motor will be driven to complete the next action. The step motor is an actuator that converts electrical impulses into angular displacement. When stepping drive receives a pulse signal, it is driving a stepper motor set according to the direction of the parameters of the stepper motor a fixed Angle (called "step Angle"), its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment. The step motor can be used as a control special motor, and it is widely applied to various open loop control, using the characteristics of not accumulated error (100% accuracy). Now more commonly used stepping motor including reactive stepper motor (VR), permanent magnet stepper motor (PM), hybrid stepping motor (HB) and single-phase stepper motor, etc.
It may not seem like high speed running so simple, step by step through this place to add general encoder closed-loop control, how much did you step in the open loop is also impossible to judge.
