The difference between stepping motor, steering machine, servo motor?
I don't quite understand what you're thinking about. Stepper motors, however, is to prevent the transient current is too large, or the motor for operating condition of the different setting of several power output of a motor, the motor can be to some extent instead of the more expensive the inverter to work, save the cost. Steering gear refers to the steering gear, which is used to control the rudder blade to change the direction of the ship. Servo MOTOR is STAND - BY MOTOR, it is used to waiting, once the malfunction of the main MOTOR servo MOTOR can be started in a very short period of time, avoid the steering MOTOR failure is ineffective, cause collision accident.
Steering gear (electronic steering machine) : the main component of the steering machine is servo motor. It contains servo motor control circuit + reduction gear group. Oh, yes, the servo motor has no reduction gear. The steering gear has a reduction gear. If it is a limit steering machine, determine the steering Angle by the potentiometer below the output shaft. Steering signal control is a kind of pulse width modulation (PWM) signal, which is easily generated by microcontrollers.
Step induction motor: a ring that converts electrical pulse signals into angular displacement or line displacement. The simple thing is that the Angle and the number of turns are controlled by the electrical impulse signal. So he just depends on the pulse signal to determine how much rotation. There is no sensor, so the stop Angle will be biased. But the precise impulse signal minimized the bias Servo motor: servo control circuit to control the speed of the motor, controlling the rotation position through the sensor. So location control is very precise. And the rotational speed is variable.
