Ko nga tikanga o te mana motika dc brushless

Brushless dc motor, ac servo system with small inertia, large output torque, simple control, the advantages of good dynamic response, rapid development, has a wide application prospect, in the field of high performance, high precision servo drive, will graduably replace the traditional dc servo system. Mīhini Brushless dc, heoi, kei te noho tonu te ripple taipana, kaore e kaha ki te mohio ki te whakahaere i te tuunga me te tere tere, ko te pai ake o te mahi o te waahanga o naianei ko tetahi o nga take matua mo te ripple taipana.

i roto i te whakatamarikitanga o te wahanga o naianei urupare ac servo system, ka taea te whakahaere i te ripple commutation torque ripple i te tere iti, engari ko te kore e taea te whakahaere i te waa o naianei te tere tere kore. Na reira, ki te rapu arotautanga o te kaupapa whakahaere aronga, me te pai ake o te mahi o te taipana commutation.

te whakamuri o te inverter i roto i te tukanga o te āhua whakakā whai hua ka, i runga i nga ture o te kowhiringa:

ture 1: whai i te tūnga rotor o te nāianei kua tutakina atu kia ngaro whakakā hāngai, a ka whakapumautia e hāngai ana ki te whakakā.

ture 2: i runga i te kaupapa o te ture 1, ka taea te whakamahi mana polarity kotahi, rua ranei.

ture 3: tukua kia ngaro e rite ana whakaroa whakaweto kati kati.

Ko te rautaki mana whakahuri whakahuri i raro i te pai me te kino o nga tohu e rua e whai ake nei hei arotake:

1. Na te iti o te ripple torque commutation (i te mea ka taeaKo te iti o te tere o te naianei)；

2. Me ngana ki te whakapoto i te wa huri.
