In view of above-mentioned, the utility model provides a kind of low voltage high-power threephase asynchronous motor, and its is compact-sized, cooling
Effect is good, can reduce motor cost and temperature rise, improves motor product quality.
A kind of low voltage high-power threephase asynchronous motor, including stator and rotor；The stator is by support and is fixed on
Stator core composition on support, the rotor are made up of rotating shaft and the cast-aluminum rotor being fixed in rotating shaft；On the support
Ventilation duct and fin are circumferentially evenly arranged, the fin includes the circumference being distributed between adjacent two ventilation ducts
Fin and the radial direction fin below every ventilation duct；Described cast-aluminum rotor one end is provided with ventilating duct and internal fan,
The end face of the ventilating duct and the iron core end face gapless of cast-aluminum rotor, can reduce the loss of motor interior ventilation volume.
Preferably, the ventilating duct and internal fan are arranged at the non-shaft stretching end of cast-aluminum rotor.
Further, the machine base outer shell is engaged with ventilation duct, and the opening diameter at machine base outer shell cooperation be 30~
38mm, ventilation duct quantity are 20~40.
Further, the quantity of the circumferential fin is 20~50, the quantity and ventilation duct of the radial direction fin
Quantity is consistent.
Further, the stator core is overrided to form by cold rolling electrical steel sheet.
Further, aluminium liquid die casting of the cast-aluminum rotor by cold rolling electrical steel sheet with high temperature melting is integral.
The utility model electric machine structure is increased cold to greatest extent by increasing motor interior circulation radiating effect
But radiating surface, so as to significantly reduce motor temperature rise.
