What is the relationship between variable frequency speed regulation, servo motor and stepper motor three? Thank you
It is a stepper motor, and the servo motor belong to motor control, that is to say in position control, is the use of pulse drive, speed and displacement by adjusting the pulse frequency and quantity of the motor control, the difference between words is quite big, with the load capacity, two motor rain are different in structure, servo motor, stepper motor is much better than that of the stepping motor is generally to choose the power slightly larger, is the kind of Daniel cart example in the start-up speed and stop speed, servo motor than the stepper motor, and speed servo motor rated speed in general 2000 or 3000., the motor speed from abroad can reach 6000, and the general application of stepping motor at 1000 rpm, but the servo motor at low speed as a stepping motor, because The vibration, then the accuracy, because the servo motor with encoder feedback, coupled with the use of the feedback of motor regulation, can achieve high accuracy, after all, step motor or motor itself is the open-loop control system, even if the temperature and pressure sensor to form a closed-loop system, but for motor do not know from speed
Then it is servo motor, variable frequency motor and the main difference with the encoder, and then transmitted to the servo motor drive, and then using the control theory, such as gain, adjust time, simply say a servo motor is a closed-loop control system, and quick start, stop, load capacity a variable frequency motor, with these characteristics, also makes the speed, torque, third position control method for high requirement application.
First talk about the frequency, because the servo motor is developed based on the frequency of the motor, variable frequency motor is user input frequency, voltage and current (or in the control panel, the voltage and current control of words on the node instructions, very detailed) then use parameters through the power electronic device to power frequency voltage is converted to the required voltage, directly reflected on a motor speed,
