stepper motor driver Performance Testing
Stepper motor driver aging test.
1, the driver performance test: mainly concentrated in the drive efficiency, harmonic analysis, three-phase imbalance analysis, interference analysis and other test items.
2, the driver response test: mainly through the motor test bench, to the motor to impose a different load, observe the load changes when the motor driver can quickly adjust the motor according to the work of the state, to assess the performance of the drive response.
3, the driver aging test: the main test driver anti-aging ability.
It is popular to say that when the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (ie, the stepping angle) in the set direction. You can control the number of pulses to control the angular displacement, so as to achieve the purpose of accurate positioning; At the same time you can control the pulse frequency to control the motor speed and acceleration, so as to achieve the purpose of speed. However, stepper motor drive directly affects the quality of its work, the specific analysis of the following:
Now the development of industrial technology, everywhere are inseparable from the stepper motor, the production process of the machine is a very cumbersome thing, requiring manufacturing personnel not only to the mechanical, electrical industry to understand, but also involves a lot of electronic and computer Knowledge of the stepper motor is mainly through the control of the number of pulses to control the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor speed and acceleration, so as to achieve the purpose of speed. If the one-sided from the current to consider how to drive, 57HB76 stepper motor minimum current can be 0.6A maximum current can be 6.0A disparity so big. It is certainly not appropriate.
Therefore, the specifications, torque, speed, current, voltage, application environment is an important reference, the stepper motor is divided by power so the drive can not be divided by power. Because now the general drive is almost subdivided the drive, so the breakdown of the problem can be ignored. Step motor driver in the quality of the machine for the quality of the machine to play a decisive factor in the quality of the machine to solve China's manufacturing machinery manufacturing a major problem for China's motor drive industry to play a catalytic role.
