Magari ya Umeme

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates in the reverse direction, converting mechanical energy into electrical energy.

Magari ya umeme yanaweza kuainishwa na mazingatio kama aina ya chanzo cha nguvu, ujenzi wa ndani, matumizi na aina ya pato la mwendo. Kwa kuongeza aina za AC dhidi ya DC, motors zinaweza kupigwa brashi au brashi, zinaweza kuwa za awamu anuwai (angalia awamu moja, awamu mbili, au awamu tatu), na zinaweza kupozwa hewa au kupozwa kioevu. Motors ya kusudi la jumla na vipimo na sifa za kawaida hutoa nguvu ya kiufundi ya matumizi ya viwandani. Motors kubwa zaidi za umeme hutumiwa kwa kusafirisha meli, kukandamiza bomba na matumizi ya kuhifadhi pampu na upimaji unafikia megawati 100. Magari ya umeme hupatikana kwa mashabiki wa viwandani, vilipuzi na pampu, zana za mashine, vifaa vya nyumbani, zana za umeme na diski. Motors ndogo zinaweza kupatikana katika saa za umeme.

Je! Ni motor ipi ya umeme iliyo bora?
Motors za BLDC zina sifa za kuvuta kama mwendo wa kuanzia juu, ufanisi mkubwa karibu 95-98%, nk motors za BLDC zinafaa kwa njia ya muundo wa wiani wa nguvu nyingi. Motors za BLDC ndio motors zinazopendelewa zaidi kwa matumizi ya gari la umeme kwa sababu ya tabia zake za kuvuta.
