In the equipment such as the motor that the pace uses extensively at sending makings machine, floppy disk numerical control machine tool, automatically driver into electric machinery, printer, plotter. Alleged pace enters electromotor is a kind of actuator; angular displacement of electric pulse translate into more told popularly: Receive signal of a pulse into driver when the pace, it presses the point of view that the direction of set turns one is secured into electric machinery with respect to drive pace. We can pass a number of control pulse to control the angular displacement amount of electric machinery, the purpose; that reachs exact location thereby still can pass control pulse frequency to control the speed with rotational electromotor and acceleration at the same time, achieve the goal of timing thereby. Current, more commonly used pace includes to react type situation enters electromotor into electromotor (VR) , magneto pace enters electromotor (PM) , Composite pace enters electromotor (HB) and single-phase type situation enter electromotor to wait. The distinction that the pace receives electromotor and general electrify motivation basically depends on the form of its pulse drive, be this characteristic, the pace enters electromotor to be able to dominate technical photograph union with contemporary number. But the; of dc servo electromotor that the pace is controlling side of performance of span of precision, speed, low speed to be inferior to conventional closed-loop control into electromotor basically applies in precision to ask so is not particularly tall circumstance. Because the pace enters electric machines and tools to have a structure,simple, dependability is mixed high the characteristic with low cost, so the pace applies extensively in each domain; that produce practice to create a field in numerical control machine tool especially into electromotor, because the pace enters electromotor not to need A/D transition, can change digital pulse signal directly become angular displacement, be considered as machine tool of optimal numerical control to carry out component all the time so. In addition, because the pace exists to carry the frequency that start for nothing into electric machinery,the pace also is put in a lot of blemish; into electromotor, it is OK that so the pace enters electric machinery low speed runs normally, dan Regao cannot be started at fixed rate, the fractionize driver precision that accompanies the different manufacturer of howl cry; that has acuteness is likely the difference is very big, fine mark jumps over big precision to control; harder and, the pace turns into electric machinery low speed from time to tome bigger vibration and noise. Although the pace enters electric machinery to already was applied widely, but the pace enters electric machinery and cannot resemble common dc electric machinery, alternating current machine is in next groovy use. It must control a system to just can be used by the composition such as circuit of drive of signal of double-loop form pulse, power. Because this uses good step to be not easy thing however into electric machinery, it involves mechanical, electric machinery, electron and computer to wait for a lot of professional knowledge. Current, the manufacturer that produces a pace to enter electric machinery is not little really, but have professional technology personnel, can develop by oneself, the manufacturer of development is very little however, major manufacturer one, 20 people, do not have even the most primary facility. Be in a kind of blind to be modelled on merely level. This gives door in product type selecting, a lot of troubles are caused in using. CNC Milling CNC Machining
