So how to choose a motor? What is the difference between the motor operation? The SUP terminal believes that it can be explained briefly. Recently, I saw an article on a website explaining the difference between brushless and stepper motors, and share with you.

1. Different control accuracy

The principle of driving is different, so the general DC brushless motor is used in places where the control accuracy is not required, and the stepper motor is used in places where the control accuracy is relatively high.

2. Different driving principles

The driving principle of the DC brushless motor and the stepping motor is different. The DC brushless motor is controlled by the alternating power supply provided by the positioning of the Hall element to control the rotation. The stepper motor is directly driven by a single pulse voltage, and does not require the positioning of the Hall element. The angle of rotation can be accurately positioned by controlling the number of pulses added to the motor.

3. Different speed

The speed of the brushless DC motor is higher than that of the stepper motor; due to the driving mode, the stepper motor has a limited number of pulses given within a certain time, so the general working speed of the stepper motor is mostly below 500 rpm, exceeding 500 The torque loss of the stepper motor decreases linearly at rpm. The brushless motor is commutated by a digital signal through a Hall sensor. Without the limitation of carbon brushes, the speed can be very high, 3000-8000r / min.

Super Terminal believes that different equipment chooses different motors, which can not only exert the efficiency of the equipment but also extend the service life of the motor. Just like we recommend customers to use the terminal products that are suitable for them, this not only exerts the functions of the terminals but also can better match other components.
