Spur geared DC motors
Nā motika DC i hoʻopaʻa ʻia i ka honua
ʻO kēia mau micro gearmotors he mea paʻakikī loa a loaʻa i nā mīkini metala piha. Loaʻa iā lākou ka lakene o 50:1 ((5, 10, 20, 30, 50,100,150,210,250,298,380,500,1000) a hiki i ka 12 volts / 24 volts a loaʻa iā ia ka torque stall o 20 oz-oz. 5 ~ 2000RPM i kēlā me kēia micro gearmotor hāmeʻa he 3mm D-shaft.
Aia kēia kaʻa kaʻa kaʻa haʻahaʻa, 12 V brushed DC motor i hui pū ʻia me ka 14: 1 planetary gear motor, a loaʻa iā ia kahi encoder 12PPR quadrature i hoʻohui ʻia ma ke kumu kaʻa, e hāʻawi ana i 12 pulses no ka huli ʻana o ka pahu puka o ka pahu pahu. He cylindrical ka gearmotor, me ka anawaena he 36 mm wale nō, a ʻo ka D-shaped output shaft he 8 mm ka anawaena a hoʻonui i 20 mm mai ka pā alo o ka pahu pahu.
Hoʻohana ʻia kahi encoder hopena Hall ʻelua-kanal e ʻike i ka huli ʻana o kahi disk magnetic ma kahi protrusion hope o ke kumu kaʻa. Hāʻawi ka quadrature encoder i ka hoʻonā ʻana o nā helu 48 no ka hoʻololi ʻana o ke kumu kaʻa i ka helu ʻana i nā ʻaoʻao ʻelua o nā kahawai ʻelua. No ka helu ʻana i nā helu no ka hoʻololi ʻana o ka pahu pahu pahu, e hoʻonui i ka ratio gear me 14. He ʻeono kala kala ʻia o ka motor / encoder, 8″ (20 knm) alakaʻi i hoʻopau ʻia e kahi poʻo wahine 1×6 me kahi pitch 0.1″.
Pono ka mea ʻike Hall i ka volta hoʻokomo, Vcc, ma waena o 3.5 a me 20 V a huki i ka nui o 10 mA. He mau hawewe huinaha ka A a me B mai ka 0 V a i ka Vcc ma kahi o 90° ma waho o ka pae. ʻO ke alapine o nā hoʻololi e haʻi iā ʻoe i ka wikiwiki o ke kaʻa, a ʻo ke ʻano o nā hoʻololi e haʻi iā ʻoe i ke kuhikuhi.
Nānā:ʻO nā torques stall i helu ʻia a me nā au he extrapolations theoretical; E kū mau nā ʻāpana ma mua o kēia mau wahi i ka wā e wela ai nā kaʻa. ʻO ka stalling a i ʻole ka hoʻonui ʻana i nā gearmotors hiki ke hoʻemi nui i ko lākou mau ola a hiki i ka hopena i ka pōʻino koke. ʻO ka palena kiʻekiʻe i manaʻo ʻia no nā ukana hoʻohana mau ʻia ʻo 4 kg⋅cm (55 oz⋅in), a ʻo ka palena kiʻekiʻe i ʻōlelo ʻia no ka torque intermittently ʻae ʻia ʻo 8 kg⋅cm (110 oz⋅in). Hiki i nā hale kūʻai ke hopena i ka wikiwiki (ma ke kauoha o kekona) ka pōʻino wela i nā wili kaʻa a me nā pulumu; ʻO ka ʻōlelo aʻoaʻo maʻamau no ka hana ʻana i nā kaʻa kaʻa DC brushed he 25% a i ʻole ka liʻiliʻi o ke au o ka hale kūʻai.
