What is the difference between stepping motor, steering engine and servo motor?
Steering gear (electronic steering gear): the main component of the steering gear is servo motor. Which includes servo motor control circuit + reduction gear set. Oh, yes, the servo motor does not have a reduction gear set. The steering gear is provided with a reduction gear set.If the steering gear is limited, the potentiometer is determined by the potentiometer below the output shaft to determine the steering angle of the rudder arm.Servo signal control is a pulse width modulation (PWM) signal, which is easily generated by microcontrollers.
Servo motor: by servo control circuit to control the speed of the motor, through sensors to control the rotation position. So position control is very accurate. And the speed is variable.
Stepper motor: is the electrical pulse signal into angular displacement or linear displacement of the open-loop control element, stepper motor parts. Simply speaking, the electrical pulse signal is used to control the angle and the number of turns. So he decided to rotate only by using a pulse signal. Because there is no sensor, so the angle of departure will be biased. But accurate pulse signals minimize deviations
