DC Stepping Gear Motor Control Becomes Very Simple
- Sep 30, 2017 -

A DC Stepping Gear Motor is an open-loop control element that converts an electrical pulse signal into angular displacement or line displacement. In the case of non-overload, the motor speed, stop the location depends only on the pulse signal frequency and pulse number, without the impact of load changes, that is, to the motor plus a pulse signal, the motor is turned a step f distance The The existence of this linear relationship, coupled with the DC Stepping Gear Motor only periodic error without cumulative error and so on. So that in the speed, position and other control areas with DC Stepping Gear Motor to control the change is very simple.

Although the DC Stepping Gear Motor has been widely used, but the DC Stepping Gear Motor does not like ordinary DC motor, AC motor under normal use. It must be double ring pulse signal, power drive circuit and other components of the control system can be used. So it is not easy to use the DC Stepping Gear Motor, it involves the mechanical, electrical, electronics and computer and many other professional knowledge.

At present, the production of DC Stepping Gear Motor manufacturers do a lot, but with professional and technical personnel, to develop their own, the development of the manufacturers are very few, most of the manufacturers only one or twenty people, even the most basic equipment are not. Only in a blind imitation stage. This gives the user in the product selection, use caused a lot of trouble. Signed in the above situation, we decided to take a wide range of induction sub-DC Stepping Gear Motor as an example. Describe its basic working principle. Hope to the majority of users in the selection, use, and machine improvement to help.

The DC generator is an electrical device that converts electrical energy into direct current.

How to convert? The following steps illustrate:

Set the prime mover to drag the rotor to turn every n turn;

The fixed part of the motor must have a magnetic field. The magnetic field may be a magnet as shown in the figure or a coil on a pole core, and a magnetic field may be generated by a direct current. Where If is called the excitation current. This coil has one pole on each pole, that is, the motor has several poles with several field coils, which are connected in series (or in parallel) to form the field windings. It should be noted that the direction of the coil through the current can not be wrong. In the above conditions, the outer conductor conducts the induced potential, which is proportional to the product of the magnetic flux density B, the effective length l of the conductor and the conductor cutting magnetic field velocity v, and its direction is judged by the right hand rule.

However, it is important to note that the potential properties of a certain rotor conductor are alternating current. And the electromotive force output by the brush is DC. This is the working principle of the DC generator.
