What Are The Common Motors Used In Robots?


The use of industrial robots is much more popular than in China, with the earliest robots replacing unpopular jobs. Robots have taken over dangerous manual tasks and tedious jobs such as operating heavy machinery in manufacturing and construction or handling hazardous chemicals in laboratories. Many robots can function largely independently, and in the future robots will cooperate with humans.

When one or more collaborative robotic applications are used to perform automated assembly operations, you can increase production speed and quality while reducing costs. It can run safely and take over repetitive tasks to free up your employees and help perform more value-added work. Handling small, irregular items can help optimize processes such as ball screw drives, mounting, and positioning. Features remarkable versatility and easy redeployment.

When humans control robots remotely, their robotic hands can easily accomplish tasks. Now we can track and replicate the movement of human fingers with artificial hands.

And the motors commonly used in robots contain three kinds: ordinary DC motors, servo motors, and stepper motors.

1. DC motor output or input for DC electrical energy of the rotary motor, called DC motor, it is able to achieve DC electrical energy and mechanical energy to convert each other's motor. When it runs as a motor, it is a DC motor, converting electrical energy into mechanical energy; when it runs as a generator, it is a DC generator, converting mechanical energy into electrical energy.


2. Servo motor is also called executive motor, in automatic control system, it is used as executive element to convert the received electric signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motor. Its main feature is that there is no self rotation when the signal voltage is zero, and the speed decreases at a uniform rate with the increase of torque.


3. Stepper motor is an open-loop control element that transforms electrical pulse signal into angular or linear displacement. In the case of non-overload, the speed of the motor, the stop position only depends on the frequency of the pulse signal and the number of pulses, and is not affected by changes in load, that is, adding a pulse signal to the motor, the motor turns through a step angle. The existence of this linear relationship, coupled with the stepper motor only periodic error and no cumulative error and other characteristics. Make in the field of speed, position and other control with stepper motor to control become very simple.

Beginners generally do not know much about micro controller control motor, the beginning can use the micro controller output PWM signal to control the DC motor, and further can try to control the stepper motor for higher control accuracy. For the motion drive of the car, you can generally choose DC motors or stepper motors, and servo motors are generally used in the robot arm, used to get the precise rotation angle.
