How to Change the Speed of DC Motor
DC motor I believe you are not surprised, the speed of this device can be controlled and adjusted. Today's editors will introduce you how to change the speed of DC motor. Interested friends and editors will learn about it together.
There are three methods of DC motor speed regulation:
First, adjust the armature voltage. Changing armature voltage and rotating speed is a constant torque speed regulation method, which has fast dynamic response and is suitable for large-scale stepless smooth speed regulation system.
Secondly, changing the main flux of the motor can only weaken the flux, so that the motor speed rises from the rated speed. It belongs to the constant power speed regulation method. The dynamic response is slow. Although stepless smooth speed regulation can be achieved, the speed regulation range is small.
In addition, changing the series resistance of motor armature in the armature loop resistance R to adjust speed can only have graded speed regulation, poor smoothness, soft mechanical characteristics and low efficiency.
Understanding the speed of DC motor is a very strict problem. The different speed of motor equipment expresses the specific working characteristics of the equipment in different time periods. So it is very important to master the method of changing the speed of DC motor. I hope you will remember this point.
