What is a triple motor? What's the difference between them?

Three motors, which is a collective term, specifically refers to servo motors, stepper motors and three-phase motors. In the field of industrial control, servo motors, stepper motors and three-phase motors are three common motor types.

Although they all belong to the category of motors, there are significant differences in working principle, control mode, application occasions and so on.

Below, we will analyze the characteristics and differences of these three motors through a vivid metaphor. First, let's discuss the three-phase motor. Three-phase motor is like driving a car, when you step on the accelerator, the vehicle will gallop out; Once the accelerator is released, the vehicle gradually slows down until it comes to a stop.

However, when the motor is parked, its position is uncertain, just as you cannot precisely control where the car is parked on the road. If you slam on the brakes, the car will stop quickly; When the brake is gently pressed, the vehicle will slow down. This characteristic makes three-phase motors perform well in certain situations where fast response is required but precise position is not required.

Second, next, let's look at the servo motor. The servo motor is more like a person walking, especially a normal person with a high degree of self-discipline. You tell him to take five steps and he will follow your instructions precisely and confirm with you when he is done.

What's more, if he encounters an obstacle while walking, such as tripping, he will voluntarily tell you that he has a problem. This ability to self-detect and feedback makes servo motors a niche in applications that require high accuracy and reliability.

Third, finally, let's talk about stepper motors. Stepper motor is like a silent person, you ask him to walk five steps, he will walk, but will not tell you that he has gone. If he tripped for some reason and missed two steps, you wouldn't be able to tell. This lack of feedback makes the stepper motor widely used in some occasions where the position accuracy is not high, but the cost is low and the structure is simple.

There are obvious differences between three-phase motor, servo motor and stepper motor in working principle, control mode and application. 1. The three-phase motor is suitable for occasions where the position accuracy is not high but the response speed is fast; 2, the servo motor is suitable for high-precision position control and feedback mechanism occasions; 3, and the stepper motor is suitable for simple, reliable control mode and the position accuracy is not high occasions. When choosing the motor, we need to choose the right type of motor according to the specific application needs and scenarios to ensure that the system can run stably and efficiently.
