Stepper motor installed with permanent magnetic rotor, stator (
: the stator core, stator windings and the frame)
At least two winding.
Stepper motor driver stepper motor can't directly to the power frequency ac or dc power supply work, and must use a dedicated driver, as shown, it is controlled by pulse generating unit, power drive unit, protection unit, etc.
Figure midpoint line surrounded by two units can be done with microcomputer control.
Stepper motor driver is a kind of electrical pulses into angular displacement of the actuator.
When stepping drive receives a pulse signal, it drives stepper motor according to set the direction of a fixed point (
Called & other;
Interval Angle & throughout;
)
, its rotation is based on the Angle of the fixed step by step.
When the rotor magnetic consistent with the stator winding, will drive the second winding.
Two winding open and shut alternately, this will lead to location of stepper motor in want.
Through the winding direction of current can also reverse.
in the stator winding of stepping motor with two, there are four step for 90 & deg; Separated. Stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control motor, is a modern digital process, the main components of control system, has extensive application. 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 & other; Interval Angle & throughout; , its rotation is based on the Angle of the fixed step by step. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating. According to provide to the stator winding of the pulse, can accurately control the step motor moving step by step. Stepper motor speed control can be achieved by offering winding pulse frequency, and direction of rotation can be change by reverse pulse sequence. internal sheet has many teeth, will help you in positioning the rotor position relative to the stator. Some of the stepper motor stator level also have teeth. According to the use of control technology, which can full step, half step or micro stepping stepper planetary gear motor control. Simple square pulse can be controlled in full of stepper motor, and advanced control technology ( Such as pulse width modulation ( 脉宽调制) ） Can be used in micro step by step. In the domestic, the masses of users to; Segmentation; Is not particularly understand, some just think, segmentation is to enhance precision ( Accuracy) , actually otherwise, segmentation is mainly the performance of the improved motor, now shows as follows: step progress motor subdivision control is precisely controlled by the driver of stepping motor phase current, the two-phase motor, for example, if the rated current of motor is 3 a, if you are using a conventional drives ( Such as commonly used way of constant current chopper) Every step driving the planetary gear motor, the motor running, in its winding current will mutations from 0 to 3 a or 3 a mutation to 0, the great changes in phase current, will inevitably cause the vibration of the motor running and noise ( Db ( dB) ) 。 If using subdivision driver, under the conditions of 10 subdivision drive the motor, step motor each run a micro, current changes in the winding is only 0. Rather than 3 a, 3 a and law of electric current is a sine curve changes, thus greatly improved the motor vibration and noise, therefore, on the performance of advantages is the real advantages of segmentation. Because subdivision driver to precisely control the motor phase current, so the driver should have quite high technical requirements and technical requirements, the cost will also be higher. Note that there are some domestic drive to take; Smooth; Smooth; Is not precise control of the motor phase current, but the rate of change of the current slow some, so; Smooth; Does not produce micro step, and subdivision microstep can be used for accurate positioning. phase current is smooth, the causes of motor torque is reduced, and subdivided control not only can not cause the motor torque is reduced, on the contrary, the torque will be increased.
It has become necessary for Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd. to continually cultivate, develop and update their skills to work successfully alongside high-tech.
Our vision serves as the framework for our electric motor suppliers and guides every aspect of our business by describing what we need to accomplish in order to continue achieving sustainable, quality growth.
electric motor suppliers is one of the best products sold in the market today.
Your co-workers, investors and clients have busy schedules, and it can be hard to get everyone in the same place at the same time for electric motor suppliers. So, it is important to create a connection between company and clients.
