Stepper motor stepper motor selected power supply voltage value is higher than voltage needed for the biggest 10%50%, the percentage for Kt, Ke, and voltage drop within the system, drive current value should be the energy needed for transfer application, keep in mind that drives the output voltage and the power supply voltage is different, and thus drive the output current and input current is not the same, in order to determine the appropriate power supply current, the demand for accounting the use all the power demand, add 5%, Glede na formulo I = P/V računovodstvo lahko dobi trenutno vrednost. Moč je prenizka, prvi je enostavno povzročiti, da je motorični izhodni navor premajhen ali celo korak metanja, drugo je enostavno poškodovati voznikovo in preklopiti napajanje, moč podrobne izbire in sistemskih zahtev uporabnikov in je tesno povezano s konfiguracijo sistema, od načela, ki je potrebna, da se v praktični zahtevi možno pridelava, ki je možno, da se pri tisoč možnih. On many occasions, as a result of the step motor current voltage is higher, for example, some stepper motor 8 a maximum output current, voltage 325 v, coupled with the magnetic shielding shell not choose aluminum alloy shell, thus form the interference of high active receiver system, make it unable to work, and interfere with the power supply, especially in high frequency, may form control system of single chip microcomputer and PC can't normal communication, serious form Računalnik z enim čipom se je zrušil, da bi uporabil normalno obliko težave, s čimer je treba rešiti težave z motnjami. Metoda reševanja težav z napajanjem motorja Stepper je naslednja: 1, opremljen z napajalnimi filtri, zmanjšanje onesnaženja na izmenični napadi. 2, z uporabo zaščitene žice zmanjšuje zunanje motnje nase ali za (napajalni kabel) preostalega sveta. 3、' One-point earthing & throughout; Principle, will power match wave filter, stepper drives (PEGround)(Drive and chassis backplane insulation)And control PULSE PULSE -DIR - pulse and directionShort answer after the lead wire, electrical grounding line, drive and motor between cable protection cover, the shielding wire are received on the casing wall ground pole, and requires good contacts. 4, try to increase the control cable and power kabel, l, n), pogonska linija motorja (u, v, w) med intervalom, preprečimo križ, na primer v postopku dvosnega pogonskega sistema je v istem primeru pogonov, da namestimo dva položaj, pogonska plošča spredaj, druga pa je poznejša, ti pa vodijo do kratko ureditve strukture.
