    Shenzhen ZhaoWei Machinery & Electronics created in 1997, which is a manufacturing enterprise R&D and production of precision transmission system with high and new technology. Owned by a professor, doctor, master and senior engineer of r&d team,  totally more than 100 people. Customers around the world to provide transmission scheme design, mold manufacturing, parts production and assembly and other one-stop service. The main products are auto parts, industrial equipment, intelligent household, standardization of medical apparatus and instruments, gear box, etc.

Customized drive system scheme of the project are: planetary gear box service plan, times easily African massager hand wheel box, the toilet cover, a base station antenna electric gear box, gear box smartphones photo printer gearbox gear motor, electric car door push rod, EPS electronic parking system slowdown motor, orthopaedic surgery wound cleaning pump, arc rack micro gear motor, etc.

DC motors possess linear relationships that allow for very predictable operation. For instance, if enough voltage is applied across the terminals of a DC motor, the output shaft will spin at a rate proportional to that applied voltage. You can take the ratio of the applied voltage over the rated voltage and multiply that number by the no load speed and get the running speed. Also, if you decide to measure and plot the current and torque, you will have a simple straight line indicating yet another directly proportional relationship.

When torque demands increase, so does the current. Plotting the torque and speed together, you will find that only two points of data are needed. Those are the no load speed and the stall torque.

The entire motion control world, including manufacturers and designers, depend greatly on the premise that all these linear relationships will hold true. And they do hold true, because the laws of physics do not change! However despite their simplicity, selecting a DC motor for an application can still be a daunting task. There are many other variables that must be taken into account including dimensions, load, duty cycle, environment, feedback considerations, etc. Perhaps decoding some of the mysteries of motor operation will shed some light on the selection process.
