What is the difference between stepper motor and servo motor and steering gear? Zhejiang Dawei Motor Co., Ltd. will introduce it to you

Stepping motor I believe everyone knows very well that it is an electronic component that converts the electric pulse signal into the step angle for angular movement. What we are saying is that the electric pulse controls the angle and the number of turns. Normally, we can only test the pulse rotation. Because he has no sensor, the stopped angle will have a certain deviation, but the pulse signal will reduce the deviation to a low level, this is still good.

What is the difference between stepper motor and servo motor and steering gear

Then let's talk about the servo motor. It mainly controls the rotation speed of the motor after controlling the circuit by servo, so that we can completely control the rotation position through the sensor, so the position control is very accurate., And this speed is also changeable.

Then it must be said that the steering gear, in fact, the main component of the steering gear is the servo motor, so it contains the servo motor control circuit. Then there is another point in the reduction gear set that the servo motor does not have a reduction gear set, but the steering gear has a reduction gear set. However, if it is a limited steering gear, then the steering angle of the rudder arm can be determined only by the potentiometer under the output shaft, then the rudder signal control is a pulse width modulation signal, so all microcontrollers can easily generate this signal.

So let's conclude that the stepping motor is mainly to prevent the starting transient current from being too large or to set the motor to a motor with several different output powers due to different operating conditions, so this motor We can replace the more expensive inverter to some extent

The main purpose of the work is to save costs. In other words, the steering gear refers to the steering device. In other words, it is used to control the rudder blade. It is mainly used to change the direction of the ship. This is more important. However, the servo motor is STAND-BY MOTOR, which is used for standby. Therefore, once the main motor fails, the servo motor can be started in a very short time, in this way, it can be very good to avoid the steering failure caused by the motor failure, and it will not cause accidents such as collision.
