Keeb kwm ntawm Stepper Motors

Lub hauv paus chiv keeb ntawm stepper motors tuaj yeem taug qab mus rau thaum ntxov xyoo pua 20th, nrog rau lawv txoj kev loj hlob mus rau ntau theem tseem ceeb.

 

Keeb kwm thiab Early Inventions (1918–1923)
1918: American inventor Frank W. Wood tau thov rau patent (tsim nyob rau hauv 1922, patent tooj US 1,408,555) ua rau lub rotor kauj ruam yog kauj ruam los ntawm energizing sib txawv ua ke ntawm tsib pawg ntawm stator coils. Qhov no yog ib qho ntawm cov txheej txheem thev naus laus zis tseem ceeb ntawm stepper motors.

Xyoo 1919: Briton CL Walker tau txais daim ntawv pov thawj British rau lub cev muaj zog reactive stepper, siv cov stator toothed-rotor qauv, nteg lub hauv paus rau qhov sib txawv tsis txaus ntseeg (VR) stepper motors.

1920: CB Chicken thiab JH Tain tau txais daim ntawv pov thawj hauv Teb Chaws Asmeskas hais txog "sandwich qauv" tsim, uas nce torque nyob rau hauv ib qho me me ntim thiab ntxiv kev txhawb nqa kev siv.

 

Thawj Daim Ntawv Thov (1920s)
Nyob ib ncig ntawm 1923: Lub British Navy tau siv cov ntsiab lus saum toj no rau cov chaw taws teeb - tswj cov phom phom thiab phom phom tswj lub tshuab ntawm kev ua tsov ua rog, siv cov tshuab hluav taws xob reactive stepper motors (VR hom) thiab hloov cov lus qhia tam sim no los ntawm kev hloov pauv kom ua tiav lub kaum ntse ntse tswj.
Nyob rau tib lub sijhawm, cov thev naus laus zis no kuj tau siv rau cov cuab yeej tsav tsheb rau torpedo tso tawm kev taw qhia, cim lub stepper lub cev muaj zog hloov pauv ntawm chav kuaj mus rau kev siv tub rog engineering.

 

Technological Evolution thiab npe
Thaum xub thawj hu ua "step-by-step motor," nws maj mam hu ua stepping motor lossis step motor.
Nws txoj haujlwm ua haujlwm yog ua raws li lub zog hluav taws xob, tig lub rotor "ib kauj ruam" los ntawm kev hloov lub zog ua ntu zus ntawm stator windings, nrog rau txhua kauj ruam sib txuas mus rau lub kaum sab xis (kab kauj ruam).
