1. 12 characteristics of stepping motor (1) Advantages of stepping motor, ① angular displacement of stepping motor (Or linear displacement) Is proportional to the number of electric pulses, so the speed of the stepping motor (Or linear speed)It is also proportional to the pulse frequency. Within the load capacity range of the Stepping Motor, its step angle and rotation speed are not affected by voltage fluctuation and load change, nor are they affected by environmental conditions such as temperature, air pressure, impact and vibration, it is only related to pulse frequency. Therefore, the stepping motor is suitable for the characteristics of the stepping motor as an actuator in the open-loop system. ② The Stepping Motor has good control performance, by changing the pulse frequency, the rotating speed of the stepping motor can be adjusted in a large range (Or linear speed), And can start, brake and reverse quickly. If several stepping motors are controlled by pulse power supply with the same frequency, they can be operated synchronously ③ the stepping motor has a fixed number of steps per rotation and runs without stepping, the step distance error will not accumulate for a long time, that is, although there is an error in each step, the cumulative error is zero after one week. These characteristics make it fully suitable for digital control of the open loop system as a servo element and make the whole system greatly simplified and reliable operation. When the speed and position detection device is adopted, it can also be used in the closed-loop system. ④ some types of stepping motors still have positioning torque when the power supply is stopped, some types of stepping motors remain electrified in some phase windings after shutdown, and also have self-locking capability and do not need mechanical braking devices. ⑤ The step angle of the stepping motor varies widely. Under the condition of small step angle, low speed operation can often be obtained without Reducer. Due to the above characteristics, stepping motors are increasingly widely used in digital control systems, such as numerical control machine tools, plotters, automatic recording instruments, numbers { In analog-to-analog conversion devices and aviation, missile, radio and other industries, Shenzhen ruite electromechanical Technology Co. , Ltd. is located in Shenzhen, Guangdong province, it is a stepping motor manufacturer integrating research and development, production and sales of stepping motor drivers, servo drivers, stepping motors, servo motors and spindle servo motors.
