Stepper motor is a more commonly used motor in production life, compared to the servo motor, many places can be replaced, the technology has been relatively mature, favored by the majority of customers.
Some friends are more curious about stepper motors, do not know its specific control method, and the coil winding process, the following Vacuz to give you an analysis of it! Hope it can help you!
Stepper motor control methods:
1. Single-step control method: this control method is relatively basic, generally used to achieve relatively simple motion control, specifically each time only need to control the turn of a step angle, because of this, so the general control accuracy are not high, the use of the field requirements are not high.
2. Half-step control method: This is actually a single-step control based on the upgrade, specifically each time only need to control the turn of half a step angle, through this half-step control method, to achieve more accurate control.
3. Micro-step control method: With half-step control thinking, the motor can be split into smaller steps for each step, that is, micro-step, accurate adjustment of the motor, the control accuracy can reach a higher state, generally need a special micro-step driver.
4. Closed-loop control method: mainly by the feedback system, to achieve accurate speed and position control, can achieve higher control accuracy, control more stable, generally to be equipped with special drivers and encoders, etc., the application area is more refined, but the cost is higher.
Stepper motor stator winding method:
Stepper motor has a variety of models, common 42, 57, 86, etc., in fact, the stator specifications, the stator needs to wind the enameled wire, generally using a special internal winding machine to wind, according to the parameters of the stepper motor stator, can be used for double-station, four-station, six-station and other internal winding machine equipment, you can single line or double line and winding way, winding to pay attention to the selection of high-quality winding machine equipment and manufacturers, debugging the machine winding machine equipment to avoid injury, broken lines, rubbing lines, scraping lines and other problems.
