Q: Multiple step motor synchronous rotation
This is easy to implement, stepping motor model parameters is the same (best high consistency stepper motor), drive type and set the same parameters, the controller program parameters are the same, suggest that in the same way pulse control multiple drives, multiple drives again (each drive and drive 2 ~ 3 stepper motor). 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: Step forward motor life calculation method
The life of a step motor is like any other product, depending on the most vulnerable part of the motor, which is the bearing. Hybrid step motor using rolling bearing, the bearing life usually calibration for 3000 hours, the actual practical can reach more than 100 million hours, sometimes 8 normal too. The so-called life 3000 hours is bearing manufacturer, is refers to under the rated load and rated under the conditions of use, motor after 3000 hours of continuous operation, still can reach the factory when the motor parameters, including noise, friction, etc. But this is only the conservative practice of the manufacturer, actually use, don't care too much!
Q: What are the advantages and disadvantages of stepping into the motor?
I pour you into the motor like garbage, but the most common thing on the market is the stepping motor. There is no benefit of stepping into an electric motor. The greatest advantage is that you can pinpoint it.
Q: What is a step motor
Stepping motor is an actuator that converts electrical impulses into angular displacement. Popular point: when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (and the step Angle). You can control the amount of angular displacement by controlling the number of pulses, so that the target is accurate. At the same time you can control the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating, made in the field of speed and position control with stepper motor to control becomes very simple.
Q: Is the stepping motor a brushless motor
The stepping motor does not replace the carbon brush, and the rotation is a rotating field driven by the step. The rotor is permanent magnet.
Q: What are the six out of step motors?
There are two windings for the step motor and there are three leads for each of these and there's a tap on the line. It's from the middle of the winding. The control method should be determined according to the wiring method. The general case is that the tapping line is ground, and the four windings in the control are reduced by half. No, you don't.
Q: How do you calculate the inertia and torque on the output shaft of the motor
The rotational inertia of the stepper motor and torque are fixed parameters, different electric opportunity have different moment of inertia and torque, the motor is not calculated made when one of the biggest parameters. You can only choose a matching machine based on the inertia and torque of your load. The moment of inertia is a square centimeter, so let's do it ourselves. Load torque and transmission parts have considerable relationships.
Q: The difference between stepping motor, steering machine, servo motor?
Step induction motor: a ring that converts electrical pulse signals into angular displacement or line displacement. The simple thing is that the Angle and the number of turns are controlled by the electrical impulse signal. So he just depends on the pulse signal to determine how much rotation. There is no sensor, so the stop Angle will be biased. But the precise impulse signal minimized the bias Servo motor: servo control circuit to control the speed of the motor, controlling the rotation position through the sensor. So location control is very precise. And the rotational speed is variable.
Q: Can the step motor be in parallel with two phases
You can. If it is a two-phase step motor with eight lines, it can be applied with single polarity, series connection and parallel connection. Unipolar wiring requires a single polarity drive, which is not very generic. If the user needs to work in low-speed electric motor torque, can be used in series connection mode, the motor current to set a small some, also to drive the output current of requirement lower; If the user needs to motor working in high speed, can be used in a parallel connection mode, the motor current to set a few bigger, drives the output current to a bigger one. For example, the 42HS03 motor in innast, which is rated at 2.3 A, will be able to work with an electric current of 1.6 A, and will be able to use the EZM322 drive. If parallel wiring is used, the electric current of the motor is about 3.2 A, and the drive of the EZM442 is required. In conclusion, the user needs to select the most appropriate step forward driver for the need to get a greater economic performance.
Q: What are the advantages of step-motor versus private motor?
Stepping motor: can control the rotation Angle accurately, angular velocity. So it can also control the speed. A (private) clothing machine: it can control the speed of the revolution, of course, it can control the speed accurately. It's a real thing, and it's not a real thing Comparison: the speed control can be satisfied, but the need to control the angular velocity must be stepped into the motor
