  Analysis of the Reasons for Stepper Motors to Become Robot Power


  The biggest advantage of Rtelligent's stepper motor is its precise position control. Geared motors require very powerful servo functions for precise position control and are difficult to lock in a fixed position. These do not apply to stepper motors.

  

Analysis of the Reasons for Stepper Motors to Become Robot Power

 

  There are several disadvantages: the same driving force, the stepper motor sinks slightly, so the power of the robot must take into account the side effects of its weight. Followed by the speed, the greater the speed of the stepper motor, the smaller the torque, so there is no DC motor or DC gear motor.

  It is easy to understand that each step of the pulse motor allows the vector field angle within the motor to be offset, allowing the motor to move in one direction. Therefore, one pulse corresponds to the displacement. Can be seen as position control. When the stepper motor is locked, the force is maximum. When the vector field changes, it needs to wait for the motor itself to move before giving the next pulse. If your stepper motor is heavily loaded, it will take some time to pulse the motor. Otherwise it is easy to cause "out of step". With a stepper motor, it can also be equipped with a reducer for any control effect. There is now a product that integrates a drive motor and is best suited for robot projects with relatively small spaces.
