Nā pōmaikaʻi o ka motika DD

Holo ʻole ʻia nā motika Servo ma muli o ka lawa ʻole o ka torque a me ke kowali i ka wā e hana ai me nā wikiwiki haʻahaʻa.ʻO ka hoʻohaʻahaʻa ʻana i ke kaʻa kaʻa e hoʻemi i ka pono, wehe ʻia a me ka walaʻau i ka wā e hoʻopili ʻia ai nā mīkini, a hoʻonui i ke kaumaha o ka mīkini.I ka hoʻohana maoli ʻana, ʻo ka ʻoki ʻana o ka pā kuhikuhi i ka wā o ka hana ʻana i loko o kahi pōʻai, a koi ʻia kahi torque hoʻomaka koke.ʻO ka motika DD, me ka ʻole o ka mea hoʻohaʻahaʻa, he torque nui a mālama i ka hana pololei a paʻa i nā wikiwiki haʻahaʻa.

TʻO ia nā hiʻohiʻona o DD motor

1, ʻO ke ʻano o ka mīkini DD i ke ʻano o kahi rotor waho, ʻokoʻa ia mai ka AC servo o ka ʻōnaehana rotor i loko.ʻOi aku ka nui o nā pole magnetic i loko o ke kaʻa, ʻoi aku ka nui o ka hoʻomaka ʻana a me ka huli ʻana.

2, ʻO ka radial bearing i hoʻohana ʻia i ka kaʻa hiki ke lawe i ka ikaika axial nui.

3, ʻO ka encoder kahi kiʻekiʻe kiʻekiʻe o ka pōʻai pōʻai.He 2,097,152ppr ka hoʻonā hoʻonā ʻaupuni pōʻai i hoʻohana ʻia e jDS DD motor, a he kumu a me ka hoʻokuʻu ʻana.

4, Ma muli o ka manaʻo loiloi kiʻekiʻe a me ke kaʻina hana kiʻekiʻe kiʻekiʻe, hiki i ka pololei o ka hoʻonohonoho ʻana o ka mīkini DD ke hiki i ka pae ʻelua.(No ka laʻana, ʻo ka pololei loa o ka moʻo DME5A ʻo ± 25arc-sec, a ʻo ka pololei o ka hoʻonohonoho ʻana he ± 1arc-sec)

ʻO DD motor a me servo motor + reducer loaʻa nā ʻokoʻa aʻe:

1: ʻO ka wikiwiki kiʻekiʻe.

2: Kiekie torque (hiki i 500Nm).

3: Hiki ke hoʻokō ʻia ka mana kūlana kiʻekiʻe, ʻaʻohe kumu hoʻokuʻu ʻia (ʻo 1 kekona ke kiʻekiʻe loa.

4: ʻO ka pololei mechanical kiʻekiʻe, hiki i ka holo ʻana axial a me ka radial holo i loko o 10um.

5: ʻO ka ukana kiʻekiʻe, hiki i ke kaʻa ke hāpai i ka 4000kg o ke kaomi ma nā kuhikuhi axial a me radial.

6: Kiʻekiʻe rigidity, kiʻekiʻe kiʻekiʻe rigidity no ka radial a me ka manawa hoʻouka.

7: He puka puka ka motika no ka hele maʻalahi o nā kaula a me nā paipu ea.

8: Maintenance-free, ola lōʻihi.

Manaʻo manaʻo

Hoʻohana pinepine nā motika DDR i ka manaʻo encoder incremental optical.Eia nō naʻe, aia kekahi mau ʻano manaʻo manaʻo e koho mai, e like me: encoder solver, encoder absolute a me inductive encoder.Hiki i nā encoder Optical ke hāʻawi i ka pololei a me ka hoʻonā kiʻekiʻe ma mua o nā encoders solver.ʻO ka nui o ka mīkini DDR kiʻekiʻe, ʻo ka grating pitch o ka optical encoder grating rule he 20 microns.Ma o ka interpolation, hiki ke loaʻa ka hoʻonā kiʻekiʻe loa e hoʻokō i ka pololei i koi ʻia e ka noi.No ka laʻana: DME3H-030, ʻo ka pitch grating he 20 microns, aia nā laina 12000 no ka hoʻololi ʻana, ʻo ka hoʻonui interpolation maʻamau he 40 mau manawa, a ʻo ka hoʻonā no ka hoʻololi ʻana he 480000 mau ʻāpana, a i ʻole ka hoʻonā me ka grating e like me ka manaʻo he 0.5 microns.Me ka hoʻohana ʻana i ka SINCOS (analog encoder), ma hope o 4096 mau manawa o ka interpolation, ʻo ka hoʻonā hiki ke loaʻa he 49152000 mau ʻāpana i kēlā me kēia kipi, a i ʻole ka hoʻonā me ka grating e like me ka manaʻo he 5 nanometers.
