synchronous motor 380v ac motor is a new-type motor with the advantage of high efficiency and energy-saving. It can be divided into two categories, VFD (variable frequency drive) synchronous motor 380v ac motor andasynchronous start synchronous motor 380v ac motor. The common feature is the rotor magnet steel structure; the difference is that there is no aluminum ring on VFD synchronous motor 380v ac motor to help to start automatically, only can start with the help of VFD and the motor speed can be adjusted by VFD. But there is aluminum ring on the rotor of asynchronous start synchronous motor 380v ac motor, so this kind of motor can start automatically without inverter. The character is the rotor rotating together with magnetic field with constant speed. Under the power of 50Hz, the rotate speed of 2-pole motor is 3000rpm; 4-pole is 1500rpm. Its speed will not changed according to the load or voltage like asynchronous motor and the speed will be a little lower than rotational speed of magnetic field.

***Motor Industries Chaos
In recent years, the competition of ac synchronous motor between suppliers is increasingly fierce. Even in Taizhou city which is a famous Motor City in China, there are many factories make different quality ac synchronous motor. Many suppliers in order to get more market share, they use inferior material for lower price. And there are many “suppliers” they purchase pumps’ accessories from others and just assemble to a whole ac synchronous motor. Some firms are even Dummy corporations, but they call themselves pump manufacturers.
Zhejiang ChuangMei Pump Co., Ltd. Never sell any renewed synchronous motor 380v ac motor, we are Alibaba International Trade Insurance Enterprise. Our synchronous motor 380v ac motor have been Exported to 58 Countries and Beijing Olympic use Feili ac synchronous motor. More than 90% customers make payment before meeting us!
***Real Customer Stories
The real story is about one of my New Zealand customer and synchronous motor 380v ac motor.
We have discussed about specification of synchronous motor 380v ac motor for 2 days, finally, customer decided to buy a sample first. Alibaba has a wholesale now, it is very convenient, customer can buy our synchronous motor 380v ac motor and pay directly. I suggest customer buy at that way, he agreed.
I made a link of synchronous motor 380v ac motor especially for that customer, same price as we talked before, but I haven’t mentioned detailed Model and specification of synchronous motor 380v ac motor in the link. He paid for that link. After payment, he was very worried(maybe we will send a wrong synchronous motor 380v ac motor to him)! Of course we will not! He became angry and sent several emails to complain even told he will complain to Alibaba and get money back.
I totally understand his worrying! It’s our first time cooperation, we never met with each other before and we only communicated for 2 days. Then, I send messages to customer’s trademanager(he was online that time) and send pictures of myself and our factory pictures, etc. Finally, customer typed “Sorry, thank you! I believe you”, I feel relieved!
All customers definitely can believe me(I am an honest and straightforward sales), and believe Feili Pump. We have our own factory in Taizhou City, Hangzhou is our sales headquarter, we have been this line for 10 years, so you definitely can believe us! We surely will make and deliver same synchronous motor 380v ac motor as we talked before!
All our synchronous motor 380v ac motor are high quality rotor with magnetic steel, its working efficiency is much better than common suppliers!

Advantages of ac synchronous motor
1. High efficiency
At 60% rated load falling faster, low underloading efficiency. Rare earth permanent magnet motor efficiency curve is high and stable, at 20% ~ 120% rated load in high efficient area.
2. High power factor
The power factor measured value of rare earth permanent magnet motor reach to limit value-1.0. The power factor curve is also high and stable.
High power factor can reduce current which can reduce the loss of stator to raise efficiency.
3. Low current
Adopting pernament magnet synchronous motor, the stator current decreases obviously.30%-50% current lower than asynchronous motor.
4. Energy saving more than 10% higher than asynchronous motor.
5. With synchronous motor 380v ac motor, speed stability and durability
Features of ac synchronous motor
1. High Energy Efficiency, motor efficiency is higher about 10-20% than common motors.
2. Small size, light weight
3. Multifunctions and Auto-protecting
4. Constant speed synchronous operation
