Q:What are the step motor parameters and characteristics?

The parameters of the stepper motor a lot, paying special attention to in practical application are stepping motor in different voltage and current, frequency under the condition of different drive torque curve, make sure that the step motor running in the process of the output torque can meet the needs of all kinds of sports equipment, otherwise easy to appear out of step and blocked.

Q:12V step motor is driven by ULN2003. How does the voltage of 12V work?

Step into the motor, the control Angle of the step motor is connected to the 10 ~ 16 feet of 2003, the power Angle is 12v. 12v, you can do it with a booster circuit, baidu 34063 application circuit, you can find it. The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed point of view, called "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.

Q:What is the difference between the stepper motor and the servo motor?

This is not likely to be similar to the servo performance, choosing servo is mainly the high accuracy and the constant torque output is better than the step motor. This gap is mainly determined by the physical structure of servo and stepper, although stepper positioning accuracy will be improved after adding the encoder, but recommend suite stepper motor torque output and high speed down very fast problem still cannot be solved, servo when in rated 3000 turn, for instance can still maintain its rated torque output, step might be to 1500 turn when the moment is only he remained one of the three points of the torque. So the step plus encoder has limited performance improvements, mostly just a publicity stunt.

Q:What is the relationship between the number of steps and the speed?

These two concepts clearly, after we again to calculate the rotational speed, with basic steps within 1.8 ° Angle of stepping motor as an example (now in the market of conventional two, four basic steps from the Angle of the hybrid stepping motor is 1.8 °), four phase eight running mode, each receives a pulse signal, around 0.9 °, if receive 400 pulses every second, so speed is 400 megabits per second x0. = 9 ° 360 °, equivalent to turn every second, every minute 60. Other things can be calculated.

Q:What is the speed of the step motor that is controlled by?

The inside of the motor drive is a ring distributor, and the ring distributor takes one step in each step, stepping into the motor, So as you change the spacing of the step pulse, you can control the speed of the step motor.

Q:What are the important technical parameters of step motor?

The phase number of the step motor: the number of coils inside the motor, the two phase, three-phase and five-phase step motor are commonly used. Number of beats: the number of impulses required for a periodic change in a magnetic field, or the state of conduction, in terms of m, or the number of impulses required to turn a tooth from an electric motor.

Q:What is the meaning of step 1, 1204, 1605,1610?

16 in 1605 is the diameter of the screw, 16mm. 05 is the lead, which is the distance of the screw to move the weight around 5mm. 1605 that is to say, the 16mm diameter of the screw will drive the load along the 5mm. 1204 means that the screw with a diameter of 12mm will move a circle and will drive the load up to 4mm.

Q:What is the meaning of the step motor drive half flow setting and attenuation setting?

Stepping drive half flow is mainly in order to reduce the heating of the motor, are generally used in stepping driving system constant current control, which means great electric motor and motionless, flows through the winding current were set according to the current work, such motor in standby, will serious fever, if adopting automatic flow, can significantly reduce the fever when standby. Some drives now have a current size of half a stream and a half current, such as innast's EZM552. The attenuation is mainly aimed at the actuator of the control method of the hysteresis loop, which is divided into fast decay and slow decay. The electric inductance of general motors is more slowly and less than the hour, and if it is a large inductance motor, it will be much more.

Q:How does the two phase step motor connect

Four lines, two for one phase. Choose two lines for one phase (A phase) and two for B. There are three states, 1. The motor runs normally. The motor is operating normally but the reverse is reversed, and then the machine is chosen for a phase 2 wire and the motor can be transmitted. The motor jitter does not work, the A phase any line with B should be interchanged

Q:What does the step motor model 17hs6615n-06b mean

The 17HS is the international standard for British dimensions, which is the hybrid step motor of the 42-seat number, which is equivalent to 42BYG stepping motors at home 6615n-06b is each manufacturer's own factory number. Each plant will establish its own naming system based on the length of the motor, the rated phase current and the static moment.
