Voltage of servo motor: relationship between voltage and speed of servo motor

1)At high speed, the speed is proportional to the voltage

2) At low speed, the voltage is lower than the decrease of speed;

3) When the speed is zero, the voltage is not zero;

4) In short, the voltage varies with the speed;

5) Voltage = back EMF + armature voltage drop.

1.Positioning or residual torque: when there is no current passing through the winding, the torque required to make the output shaft of the motor rotate. 2.Driver: an electrical control device used to run the stepping motor. This includes power supply, logic programmer, switching element and a variable frequency pulse source which determines the step rate. 3.Dynamic torque: the torque produced by the motor at a certain step rate. The dynamic torque can be expressed by PULL IN torque or PULL OUT torque.

Matters needing attention

1.Oil and water protection of servo motor 1) The servo motor can be used in the place that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. Therefore, the servo motor should not be placed or used in the environment of water or oil invasion. 2) If the servo motor is connected to a reduction gear, the oil seal should be filled when using the servo motor to prevent the oil of the reduction gear from entering the servo motor 3) The cable of servo motor should not be immersed in oil or water.

Performance comparison between servo motor and stepping motor

As an open-loop control system, stepping motor has essential connection with modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or full digital AC servo motor is mostly used as the executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), they are quite different in performance and application. This paper compares the performance of the two.

Performance characteristics of Panasonic Minas series Panasonic AC servo

The output power of Panasonic AC servo motor is generally 0.1-100 W, and the power frequency is divided into 50 Hz, 400 Hz, etc. It is widely used in various automatic control and recording systems 1.Miniaturization design 1) Through the best thermal analysis of the driver, the miniaturization is realized. Compared with the past, the volume is 75% and the weight is 80% 2) The new punching process of thin die steel plate has greatly reduced the iron loss, shortened the motor length (70% in the past) and reduced the number of drive models. It adopts current grading method to prepare and maintain. One driver is suitable for multiple motors and can identify automatically.
