ʻOi aku ka paʻakikī o ke koho ʻana i ka magnet motor stepper ma mua o BLDC - no ka mea, hele mai nā motor stepper i nā ʻano hoʻonohonoho like ʻole, kēlā me kēia me nā koi magnet like ʻole.

Nā Motika Stepper Hybrid (50-Pole Standard)

ʻO nā motika stepper hybrid ke ʻano maʻamau o ka motika stepper, me ka hoʻohana ʻana i kahi rotor claw-pole 50-niho i ka hoʻonohonoho maʻamau.

·ʻAno Magnet: Hoʻohana ke ʻano kuʻuna i kahi magnet cylindrical axially magnetized + ʻelua rotors claw-pole, ʻaʻole he magnet apo

ʻO nā motika servo nā koi magnet apo paʻa loa ma waena o nā ʻano motika ʻekolu - no ka mea, ke alualu nei nā ʻōnaehana servo i ka kaohi kūlana pololei a me ka ripple torque liʻiliʻi. Hoʻopili pololei ʻia kekahi ʻano magnet ʻole ma ka hoʻopuka motika.

Nā Koina Hoʻohālikelike Flux (< ±2%)

Pono nā magnet apo mīkini servo i ka hoʻolaha like ʻana o ka flux air-gap. ʻO ke kikoʻī:

ʻAʻole pono e ʻoi aku ka ʻokoʻa o ka ikaika o ke kahua magnetic ma waena o nā pou e pili ana ma mua o ±2% - ʻoi aku ka paʻakikī ma mua o BLDC's ±5%

Ma Fullzen Technology, mālama mākou i nā moʻolelo hahai piha a kākoʻo i ka hoʻouna ʻana o ka PPAP Level 3 no nā mea kūʻai aku kaʻa.

Q: Pehea ʻoe e pale ai i ka demagnetization i nā noi motika wela kiʻekiʻe?

A: ʻEkolu mau mea e pale ai i ka demagnetization: ke koho pololei ʻana o ka papa (SH grade no 150°C, UH no 180°C), ka palena coercivity kūpono (pono ʻo Hcj e ʻoi aku ma mua o ke kahua demagnetization ma ka liʻiliʻi he 30%), a me ka hoʻolālā thermal e mālama i ka mahana o ka ʻili magnet ma lalo o ka helu kiʻekiʻe o ka papa. Paipai mākou e holo i kahi loiloi piʻo demagnetization ma ka mahana hana ʻino loa o ka motika ma mua o ka hoʻopau ʻana i ka papa.

Q: He aha ka manawa alakaʻi maʻamau no nā magnet apo motika maʻamau?

A: Hoʻouna ʻia nā laʻana maʻamau i nā nui maʻamau a me ka papa N42SH i loko o 7-10 mau lā. ʻO nā kikoʻī maʻamau me nā mea hoʻopili magnetizing hou e pono ai he 15-25 mau lā no nā laʻana mua. ʻO ka manawa alakaʻi hana nui he 15-20 mau lā ma hope o ka ʻae ʻia ʻana o ka laʻana, ma muli o ka nui o ke kauoha a me ka paʻakikī. Pono nā apo multi-pole me 24+ mau pou i ka manawa hoʻopili hou. Ma Fullzen Technology, mālama mākou i ka waihona o nā mea maka maʻamau e hōʻemi i ka loli o ka manawa alakaʻi.
