Stepper Motor Reprap 3D17

Q:Choose dc motor or stepper motor: See purpose and precision, not high dc, an H circuit, PWM driver OK. It's a little bit more of a simple thing to do when you step into an electric machine, and you're going to have to do it yourself. Select the parameters that are measured by the step Angle and the torque metropolitan area when stepping into the motor.

Q:What is the difference between the stepper motor and the servo motor?: Step by step with encoder just have one more position compensation link, accuracy will be a little higher, but the moment ring cannot be compensated, so can't completely accurate positioning, with servo is not a class, also won't become rice is like a barnyard grass farewell

Q:What is the step in the step motor: Stepper motor has a technical parameters: no-load start frequency, the stepper motor under no-load condition can normal boot pulse frequency, if the pulse frequency is higher than the value, the motor does not start properly, may be lost or blocked. In the case of load, the start frequency should be lower. If you want to make the motor to achieve high-speed rotation, the pulse frequency should be to accelerate the process, namely the start frequency is low, and then in a certain high frequency acceleration to want (motor speed from low speed to high speed).

Q:In addition to using the PLC to step the pulse signal to the motor controller, what els: Single chip, motion controller, motion control board etc. As long as can send pulse of all can.

Q:Is the stepping motor way?: It is usually powered by a dc switch, and a computer sends a pulse signal to drive the step motor

Q:How do you give in to the motor revolution for 3 seconds: 1, directly with microcontroller programming to control the amount of output pulse and the number of pulses output corresponding to 3 seconds for the motor turn round to go, if want to consider the fine fraction of drive is set. Step by step motor is an open loop controlling element which converts 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 Angle, known as the "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:The relationship between the torque of the torque and the torque of the motor shaft output when the motor connection is reduced by 1:10.: Stepper motor connection speed reducer will increase after the output torque, but output speed will also decline, in the design is important to identify what is the speed of the processing of good equipment? If the device is running at a high speed, it is better to choose the machine with the greater torque and reduce the reduction ratio.

Q:Which is good for servo motor and stepper motor: Servo motor (servo motor) is the engine that controls the operation of mechanical components in servo systems. The servo motor can control the speed, the position precision is very accurate, can convert voltage signal to torque and speed to drive the control object. Servo motor rotor speed controlled by the input signal, and can be rapid response, in the automatic control system, is used as actuators, and has a small electromechanical time constant, high linearity, initiating character such as voltage, can convert the received electrical signal to the motor shaft angular displacement or angular velocity on output. Divided into two major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform.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 Angle, known as the "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:How to adjust the speed of the step motor: There is a certain extent to the speed of the step motor. Generally speaking no speed, only the step Angle, the frequency and the pull frequency. In order to adjust the speed, we need to talk about the several phases of the control step motor. When it comes to several shots, it's about how often it works. The faster you can control the motor, the shorter the time it takes to move one step into the corner, and the faster it will turn into the motor. If the frequency of your control is fixed, then the next phase of the beat determines the next step in the Angle. That's how fast the next phase of the action will be. Of course, the fastest time is not less than the period of the control phase. Finally: Let's say that one set of pulse signals move a step into the corner, and the faster the next set of pulses come, the faster they move. In contrast, the slower the next set of pulses came, the slower they went. Adjust the interval time of each set of pulses to achieve the speed of the adjustment step motor.

Q:How is the speed of the four-phase eight step motor?: Step Angle: corresponding to a pulse signal, the angular displacement of the rotor of the motor is expressed in theta. Theta = 360 degree (the number of rotors), in the case of the normal two and four phases, the rotor teeth are 50 teeth motor. Four run time interval Angle is theta = 360 degrees/(50 * 4) = 1.8 degrees (commonly known as a whole step), eight beats runtime interval Angle is theta = 360 degrees/(50 * 8) = 0.9 degrees (commonly known as half step). 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.
