Acceleration and deceleration control of stepping motor

Acceleration and deceleration control of stepping motor

Everyone knows that stepper motors are different from ordinary motors, and they can be used when they are plugged in. Stepper motors can only be controlled by digital signals. When pulses are supplied to the driver, the control system sends too many pulses in a short period of time, that is, the pulse frequency is too high, which will cause the stepper motor to stall.

AC servo motor needs a driver to run

AC servo motor needs a driver to run

Everyone knows that the AC servo motor needs a driver to run. The speed of an ordinary AC motor is generally about 1400 rpm. Why is it 1400? Because the general power supply is 220V, 50Hz, that is, the phase changes 50 times per second, and usually the motor is 4 poles, that is, change the phase twice and make a circle, plus the ordinary AC motor is not synchronous, it is an AC asynchronous motor, so it is a little slower than the theoretical speed of 50/2*60=1500, so it is usually about 1400 rpm.

The future development trend of the servo motor industry

The future development trend of the servo motor industry

After the modern AC servo system has undergone the change from analog to digital, its internal digital control loop has been ubiquitous, such as commutation, current, speed and position control, etc.; its realization is mainly through new power semiconductor devices, such as high Functional DSP plus FPGA, and even servo-specific modules are also commonplace.
