![]() Each Pulse to the Stepper Motor moves it a given number of Degrees ( Radians ) of Rotation. It could also be based on the PWM value and the Rotational Movement of the Servo Motor.Ī “stepper motor” is not Better or Worse, just different. ![]() I would have to guess that the reason the Servo is not able to rotate more that 120 Degrees, is because of that feedback mechanism. This is based on a feedback device in the Servo. The Vex Servos “maps” a given PWM output from the Vex Controller to a Position in the rotation of the Servo. a vex motor doesn’t stop at a certain point, it continously rotates at different speeds. servos are programmed to stop at certain degrees on the servo. a regular motor and servo from vex are the same thing other than the fact that the servo has a plastic stop There’s a name for a vex 360 degree servo.
