Stepper motor as a kind of commonly used electric actuators, widely used in automatic control field.
Stepper motor operation be fitted with a special driving power, drive the power output of the pulse signal and the direction of the signal control from outside.
Each pulse signal can make the stepping motor rotate a fixed Angle, this Angle is called interval Angle.
The number of pulses determines the total rotation Angle, the frequency of the pulse to determine the speed of rotation.
determines the direction of rotation direction signal. In terms of a transmission ratio to determine the specific equipment, no distance, speed signal feedback loop, only need to control the number and frequency of the pulse can control equipment the moving distance and speed of the moving parts; And direction of the signal can control the direction of the mobile. So, for those applications where control accuracy is not high, with open loop control is a very technical scheme of the electrical control system of simple and economic. In addition, the operating method of stepping motor subdivision is very practical, although its steps from the Angle of subject to the conditions of mechanical manufacturing, cannot make very small, but you can make the stepping motor by means of electrical control operation from each whole steps into m a small step to complete, in order to improve the precision and stability of the equipment operation. Control stepping motor power pulse and direction of the signal source commonly used CNC system, but for some in the running process determine the moving distance and the speed of specific equipment, PLC ( Programmable controller) As an ideal technology solutions.
1. Screw pitch refers to: the distance between the screw every two silk, such as, pitch of 5 mm.
2. Corner of the stepper motor is to point to: a pulse driving stepper motor rotation Angle, such as, the stepping Angle of 1. 8 degrees of motor, turn a circle will be: 360 degrees & times; 1. 8 degrees = 200 pulses.
3. Subdivision drive refers to: the step Angle and then divided into N parts, such as, 8 subdivision is to 1. 8 degrees of stepper Angle is divided into eight points again, planetary gear motor every step into after segmentation is 1. 8 degrees & divide; 8 = 0. Turn 225 degrees, a circle is: 360 degrees & divide; 0. 225 = 1600 a pulse.
4. Refers to the motor parameters: every step into the length of walking, pitch of screw for 5 per round 5 mm, each step is 5 & divide; 1600 = 0. 003125 mm/step by step.
5. Pulse equivalent refers to: the number of pulses to every 1 mm, with 1 divided by the motor parameters is the pulse equivalent, such as: 1 & divide; 0. 003125 = 320 step by step.
Whether it's automation or artificial intelligence, the rapid convergence of technology and business often determines electric motor suppliers’s competitiveness.
