Q:What is a step motor
The step motor is also called the electric pulse motor. It is an actuator that converts electrical pulse signals into mechanical angular displacement. To enter an electrical pulse, the rotor turns a corresponding step Angle whenever the motor winding receives an electrical pulse. The magnitude and speed of the rotor's angular displacement are proportional to the number of electrical impulses and their frequencies. And synchronize with the input pulse in time. As long as the number of control input electrical impulses, frequency and motor winding current phase sequence can achieve the desired Angle, rotational speed and steering, easy to digital control by microcomputer. Second step motor characteristics of stepper motor working condition not easily affected by various interference factors, such as the size of the power supply voltage fluctuations, current and waveform changes, temperature, etc.), as long as they did not cause the size of the step motor to produce the phenomenon of losing step before, will not affect the normal work; Stepper motor step away from the Angle of error, the rotor turns after a certain number will also appear cumulative error, but the rotor turns after a turn, the cumulative error for "zero", not long-term accumulation. Control performance is good. Step motor is widely used in the electromechanical integration system of open loop structure, so that the system is simplified, such as simple CNC system. The type of the three-step motor
Q:How do you control step by step motor?
The rotation of the stepper motor is a fixed Angle (called "step Angle"), step by step, its characteristic is no accumulated error (accuracy of 100%), so widely used in all kinds of open loop control
Q:Why does the stepping motor stop the brakes
The step motor itself has the torque, and the torque of the electric motor can be used to lock the motor, which is equivalent to the brake. But if the stepper motor torque is not enough big, need more locked torque, or outage hind leg motor keep lost moment can consider the use of the stepper motor with brake. Stepper motor brake generally have a spring type and permanent magnet, including permanent magnet brake faster response speed (within 50 ms can lock), low noise, less heat, can be electric braking or electric braking, but off the electric brake is more commonly used. The permanent magnet cost is a bit more expensive, the manufacturer is relatively few, can see the information and explanation of the permanent magnet brake on the website of shenzhen weicott electromechanical co., LTD. With big reduction ratio of the reducer and a stepper motor keep torque or braking torque can also have the brakes, but good reducer more expensive than the brake, if just for the sake of brake USES think there is no need for this choice.
Q:Does the stepping motor start a lot?
Look at the multi-power step motor, pulse drive, 5V voltage, some under 200mA
Q:Why does a step in a motor have a lot of heat
There are several reasons for stepper motor fever: The current of the actuator is larger than that of the motor. The speed of the motor is too fast. The inertia of the motor and the torque of the positioning torque are high, so even the medium speed can be hot, but it does not affect the life of the motor Motor demagnetization points in 130-200 ℃, so the motor in the 70-70 ℃ belongs to the normal phenomenon, as long as less than 130 ℃, generally do not have what problem, if you really feel overheated, sent the current set of drive motor about 70% of the rated current or speed reduce some.
Q:The difference between the servo motor and the step motor
I take it very seriously, to answer the question of science, to be sure, not to mislead the questioner, and the answers of these answers are misleading Performance comparison of stepper motor and ac servo motor The step motor is a discrete motion device that is intrinsically linked to modern digital control technology. In the domestic digital control system, the application of stepping motor is very broad. With the advent of full digital communication servo system, ac servo motor is increasingly applied to digital control system. In order to adjust to the development trend of digital control, most of the motor control system is used as an actuator motor. Although the two are controlled in similar ways (pulse train and direction), there are significant differences in performance and application situations. Now compare the performance of the two.
Q:What is the step length of the step motor? How do you walk the motor in step?
Step length and you drive ratio and mechanical structure segment have relationship, if there is no subdivision, a pulse step, usually a two-phase motor stepper Angle of 1.8 degrees, usually a four phase motor stepper Angle of 0.9 degrees, the fine fraction (2 ~ 64) is divided by the number of drives a pulse Angle. See you speed ratio of the machinery, if you turn motor omega, mechanical mobile d at the end, your ratio is 2 PI * d/omega, with these you can calculate, hope to help you.
Q:What is the control Angle of the PLC step motor
In DRVI and DRVA commands, there is a value in the control velocity, you can change the speed by using D memory, changing the number in D memory
Q:What is the way in which the step motor ring is distributed?
Step motor drive. It's the rotation of the voltage, the rotation of the field, so that the motor can rotate. In general, our access to the motor is a pulse sequence, the pulse sequence needs to pass into the recycle in each motor phase winding, requires the circular distribution, circular distribution, general test drive to complete, that is, to drive you into the pulse sequence, the drive ring automatically assigned to each winding stepping motor.
Q:How to determine the pulse number of the step motor
Stepper motor as a kind of control precision displacement and a wide range of speed regulation of motor, its rotation is inherent interval angle-angle (determined by the mechanical structure of rotor and stator) running step by step, every step is characterized by rotation, step away from the Angle of constant, can keep the position of the precision. So no matter how many times you spin, you don't get the error. Because the control method is simple, the cost is low, widely applied to various open loop control. The moving motor needs to be driven by a power electronic device with pulse distribution, which is the step motor drive. It receives the pulse signal from the control system, according to the structure characteristics of stepper motor, pulse sequence distribution, realize to control the angular displacement, rotation speed and direction of rotation, braking load state and free state. The control system sends an impulse signal that drives the step forward motor to rotate a step Angle through the driver. The speed of the step motor is proportional to the frequency of the pulse signal. The angular displacement is related to the number of pulses. Stepper motor stop rotating, can produce two kinds of state: can produce brake load or part of the largest holding torque (often referred to as the brakes to keep, need not electromagnetic brake or mechanical brake) and the rotor in the free state (external thrust can be driven easily rotate). The step motor drive must match the type of the step motor. Otherwise, it will damage the step motor and drive.
