Stepper motor must, supply drive voltage affect the performance of motor is large, the higher the voltage, the step motor can produce "born of torque is larger, the more need high speed application occasions (such as 3 d printing needs high-speed environment), but the heating of the motor with the increase of voltage, current and increased, so attention should be paid to the temperature of the motor should not exceed the maximum limit. For home 3D printers, a suitable drive can better match the motor, as well as balance noise and heat. Suitable for 3 d printing motor-driven Toshiba stepper motor drive in China, there are still some people know about "niche" is not particularly, segmentation is not only in order to improve the precision of the main is to improve the performance of the motor, now shows as follows: stepping motor subdivision control is precisely controlled by the driver of stepping motor phase current, the two-phase motor, for example, if the motor rated phase The current is 3A. If the motor is driven by a conventional driver (such as the common constant current chopper mode), the current in its winding will change from 0 to 3A or from 3A to 0 at each step of the motor operation. The great change of phase current will inevitably cause vibration and noise in the motor operation. If A subdivision driver is used and the motor is driven in A state of 10 subdivisions, the current change in the windings of the motor is only 0.3a instead of 3A per run - micro step, and the current is positive
The string curve changes regularly. This greatly improves the vibration and noise of the motor. Due to the precise control of the phase current of the motor, there are quite high technical and technological requirements for the driver. Costs will also be higher. Therefore, for many 3D printer manufacturers in China, it is extremely important to have a product that meets technical requirements and maintains cost-effective performance.
