Application of DC Motor in Robot Field
In robotics applications, drive motors are a serious consideration and DC motors have specific capabilities that make them an ideal choice for small applications. There are four types of DC motors. In simple terms, a DC motor converts DC electrical energy into mechanical energy. This is different from AC motors, which is to give AC power to the motor at the most basic level, DC motors are very suitable for use in the field of robotics, because they allow the robot to be able to charge, which provides great for different robot applications. advantages, especially for mobile and collaborative robots.
This is not to say that the robot can be used in the robot like an AC synchronous brushless servo motor, which is helpful for the precise control of the robot's movement. The drive electronics for these motors operate from DC power.
To determine your drive motors, you first need to create an overview of the robot to determine its size, its weight, its speed, operation mode, and working environment, as well as the joint motion it needs. All of these factors will inform your choice of drive motor.
Besides the use of batteries to facilitate movement, the key to making DC motors well-suited for robotic applications is the speed variable and torque.
speed variable
A desirable characteristic of a DC motor is that it can provide variable speeds - a wide range of speeds below and above the rated speed. There are three ways to control the speed of a DC motor. Because the motor speed is directly proportional to the supply voltage. By changing the supply voltage, you can change the speed. Also, due to field winding issues, the speed of the motor is inversely proportional to the flux. The speed of the motor, which is inversely proportional to the armature voltage, decreases. By changing the armature voltage and impedance, the speed of the motor can be changed.
torque
The main advantage of using DC motors in robotics is their high torque characteristics. They are capable of a high starting torque for driving heavy loads. They are also capable of rated speed over constant torque while shaft power is different from speed.
further consideration
It's worth considering that DC motors are exempt from reactive power - this isn't real power at all, but refers to power in volts versus amperes. Because there is no additional power requirement to supply the load. In addition, in addition to rapid start and acceleration. DC motors are equally effective when rapid reversing and stopping are required.
Although they are an expensive option, DC motors offer many capabilities that make them an ideal drive motor in robotics applications.
