Seek information about stepper motors.

Supplement; Stepper motors generally have drivers, and different models and manufacturers have different drivers, so they have to be used according to the manufacturer's manual.

The selection of stepper motor first depends on the torque requirements and how much load it drives;

Look at the current and inductance size. The rated current of the stepper motor determines the choice of the stepper motor driver, and the inductance is small and the speed rises quickly, and the same is true for the high current. Usually the current is related to the inductance, and if the motor current of the same size and length is large, the inductance is relatively small, and the inductance is relatively large when the current is small.

The following steps should generally be followed when selecting a stepper motor:

Torque to power conversion.

The stepper motor is generally used in a wide range of speed regulation, and its power is varied, generally only measured by torque, and the torque and power are converted as follows:

p= ω•m

2π•n/60

p=2πnm/60

P is the unit of power in watts, is the angular velocity per second, the unit is radians, n is the speed per minute, and m is the moment unit is Newton meters.

p = 2 fm 400 (half-step operation).

where f is the number of pulses per second (pps for short).

1. The stepper motor is an open-loop control element stepper motor device that converts the electrical pulse signal into angular displacement or linear displacement. In the case of non-overload, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the change of load, when the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, called the "step angle", and its rotation is to run step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

2. The stepper motor is a kind of induction motor, its working principle is to use electronic circuits to turn the direct current into time-sharing power supply, multi-phase timing control current, use this current to supply power to the stepper motor, the stepper motor can work normally, and the driver is to supply time-sharing power for the stepper motor, multi-phase timing controller.

3. Although stepper motors have been widely used, stepper motors cannot be used under conventional conditions like ordinary DC motors and AC motors. It must be composed of a double ring pulse signal, a power drive circuit, etc., and the control system can be used. Therefore, it is not easy to use stepper motors well, and it involves many specialized knowledge such as machinery, motors, electronics, and computers.

As an actuator, stepper motor is one of the key products of mechatronics, which is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, and they are used in various fields of the national economy.

A stepper motor is an actuator that converts BAI electrical impulses into angular displacements. Popular one.

zhi point to say: when stepping to drive dao

The actuator receives a pulse-specific signal, which drives the stepper motor to rotate at a fixed angle (and step angle) in the set direction. You can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency, so as to achieve the purpose of speed regulation, making it very simple to control with a stepper motor in the control field of speed and position.

There are more details in the article to step in.

Structural self-classification of motors. Simple.

Bai said that the stepper motor is a special motor that can realize the position control system under the condition of open-loop control, mainly working in low-speed applications, and generally requires a special stepper driver to support the application.
