Akụkọ

A na-achịkwa moto DSpower servo moto site na Modth Width Pulse (PWM). Usoro njikwa a na-enye gị ohere idobe ogwe mmepụta nke servo nke ọma site n'ịgbanwe obosara nke ọkụ eletrik ezigara na servo. Nke a bụ ka ọ si arụ ọrụ:

Modulation Width Pulse (PWM): PWM bụ usoro na-agụnye izipu usoro ọkụ eletrik n'otu oge. Oke isi ihe bụ obosara ma ọ bụ ogologo oge nke usu ọ bụla, nke a na-atụkarị na microseconds (µs).

Ọnọdụ etiti: Na servo a na-ahụkarị, pulse nke gburugburu 1.5 milliseconds (ms) na-egosi ọnọdụ etiti. Nke a pụtara na ogwe mmepụta nke servo ga-adị na etiti ya.

Njikwa ntụziaka: Iji chịkwaa ntụziaka nke servo na-atụgharị, ị nwere ike ịhazigharị obosara usu. Dị ka ọmụmaatụ:

Ihe na-erughị 1.5 ms (dịka ọmụmaatụ, 1.0 ms) ga-eme ka servo tụgharịa n'otu akụkụ.
Ụda nke karịrị 1.5 ms (dịka ọmụmaatụ, 2.0 ms) ga-eme ka servo tụgharịa n'akụkụ nke ọzọ.
Njikwa ọnọdụ: obosara pulse kpọmkwem na-ejikọta ya na ọnọdụ nke servo. Ọmụmaatụ:

Usu 1.0 ms nwere ike dabara na -90 degrees (ma ọ bụ akụkụ ọzọ akọwapụtara, dabere na nkọwa nke servo).
Usu 2.0 ms nwere ike dabara na ogo +90.
Njikwa na-aga n'ihu: Site na izipu akara PWM na-aga n'ihu na obosara usu dị iche iche, ị nwere ike ime ka servo tụgharịa n'akụkụ akụkụ ọ bụla achọrọ n'ime oke ya akọwapụtara.

Ọnụego Nwelite DSpower Servo: Ọsọ nke izipu akara PWM ndị a nwere ike imetụta ngwa ngwa servo na-anabata yana otu ọ na-aga nke ọma. Servos na-anabatakarị mgbama PWM nke ọma na ugboro ole na nso 50 ruo 60 Hertz (Hz).

Microcontroller ma ọ bụ Servo Driver: Iji mepụta na zipu akara PWM na servo, ị nwere ike iji microcontroller (dị ka Arduino) ma ọ bụ modul servo ọkwọ ụgbọ ala raara onwe ya nye. Ngwaọrụ ndị a na-ewepụta akara PWM dị mkpa dabere na ntinye ị na-enye (dịka ọmụmaatụ, akụkụ achọrọ) yana nkọwa nke servo.

Nke a bụ ọmụmaatụ na koodu Arduino iji gosi otu ị nwere ike isi jikwaa servo site na iji PWM:

N'ihe atụ a, a na-emepụta ihe servo, na-ejikọta ya na ntụtụ kpọmkwem, mgbe ahụ, a na-eji ọrụ ide ihe iji dozie akụkụ nke servo. servo na-aga n'akụkụ ahụ na nzaghachi na mgbama PWM nke Arduino mepụtara.
