Y (IP44) three-phase asynchronous motor has the following good performance and structural features

(1) high efficiency level.Y series (IP44) small rotor three-phase asynchronous motor to keep the J02 series motor efficiency level is higher,the advantages of the weighted average efficiency is 0.413% higher than J02 series,Reached the international level.Due to the improvement of motor efficiency,has brought the huge power saving economic benefits to society.(2) the starting performance is better.Y series (IP44) motor series of locked-rotor torque than 33% higher than the average J02 series motor,starting torque reach JQ02 series high starting torque motor level,The minimum torque had guaranteed in more than 0.8 times the rated torque,and most also meet or exceed 1 times the rated torque.Therefore,the starting performance is very good,with load Starting is also very well.(3) low noise small vibration.Y series (IP44) audio power noise standards set by the three-phase asynchronous motor,according to the noise limit is divided into l and 2,for users to choose.Due to this series adopts special motor With bearing,thus greatly reduce running noise,checked by actual measured the noise lower than J02 series actual level for about 5-10

decibels,vibration is better than J02 series motor has decreased significantly.(4) the protective

performance is better.Y series (IP44) three-phase asynchronous motor's structure design has been

satisfied to the solid content and splash water protection requirements,so it can effectively prevent

the foreign body acmotor2.blogspot.com for motor and people The body of the damage.(5) the reliable running long service life.Y series (IP44) three-phase asynchronous motor's winding adopts class B insulation.When no more than 1000 meters above sea level,the temperature of the cooling centrifugal pump air is not more than 40 ℃,the motor Son of winding temperature rise limit method (resistance) less than 80 k.Therefore,in addition to a handful of electric motive specifications generally have more than 15 k temperature margin.The rise of temperature of the large margin can Extend the service life of motor and improve the reliability of the motor running.(6) beautiful appearance and easy.Y series (IP44) three-phase asynchronous motor end cover,connection Box cover,wind the appearance of main structure parts,such as older than traditional products to beautiful,generous.All series motor than J02 series volume shrink by an average of 15%,the average weight Reduce 12%.
