When using step motor drive is facing many challenges, also will encounter many problems need to solve, under the introduction in the operation of the stepping motor drives in what problem appears:



1. The machinery and equipment ( Composition: drive, transmission, etc. ) Users, reducing the noise of the stepper planetary gear motor is urgent demand, in order to avoid cause uncomfortable feeling. Designers must also be able to compensate any outside noise or vibration in the system. Again, whether it is due to limited living space, or user preferences, high consumer demand for compact scheme is an ordinary consumer trends. This trend lead to more small size and low noise of the motor is more popular, but that in attempts to compensate for other design requirements are not always have the possibility.



2. The use of high voltage power supply drive stepper motor drive widely used in industrial equipment ( Such as industrial robots) And motor, motor drives the durability and safety is very important. 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 drive 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 speed regulation and positioning. Not to mention the engineers need to select reliable can control the speed of motor. Stepper motor drive sometimes also can appear some fault, for example, once started, drive an external fuse is burning, equipment can not run.



3. Application and related design engineer mostly for motor drive planetary gear motor driver IC and components with low energy consumption and high efficiency. Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper planetary gear motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller. Therefore, will need to use the built-in fan in internal circulation cooling, in order to reduce heat and heat management. So the engineer may require low power ( Refers to the object of the work done in a unit time) Loss, it also requires strong, have efficient cooling function of the motor.


Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd. have now make a decision to enlarge our company in other countries.
Energetic, optimistic entrepreneurs often tend to believe that sales growth will take care of everything, that Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd. will be able to fund our own growth by generating profits.
Being focused on the goals of electric motor suppliers, our team, and most importantly, ourselves is critical to long-term success.
Although the core manufacturing factor of electric motor suppliers is high technology, smart customers know that we need to enhance our material quality and producing standard.
People are more likely to listen to an expert than just anyone off the street. So, while pack mentality is important, having a relevant expert speak to the effectiveness of a brand's product as Zhenyu is essential to converting new consumers as well.
