three phase ac variable speed industrial sewing machine electric motors

Energy-Saving and High Running Efficiency: After the permanent magnet synchronous electric motor with permanent magnet embedded permanent magnet, In running, the rotor is no induced current, and no loss resistance of rotor, it can improve the motor's efficiency 4% ~50%. Due to the water magneo roto excitation no induced current, to make motor power's factor colse to 1.

e.g Permanent magnet synchronous motor in the load rated >20%, the operation efficiency and power factor change not big, And running efficiency >80%, please check below:

1. Asynchronous starting permanent magnet synchronous motor; 2: Asynchronous motor 

Mini Size and Light Weight: compare with same power asynchronous motor smller 1 to 2 stand, More compact size :

Seat No. and Power comparison

Longer Working Life:current decrease, reducing temperature rise, longer life of motor.

High Strating Torque and Overload Capacity: smaller the moment of inertia, big start torque, wider operating frequency control is simple and reliable; Adopts frequency conversion vector control method, high control precision and reduce the fault segment.

Non-inductive permanent magnet synchronous motor using IMP magnetoresistance effect, greatly improve the motor ,overload capacity, the over-load capacitiy more than 2 times .Compared with asynchronous motor, with more hard mechanical properties, long overload, torque characteristic show below picture:

Strong Universality and Applicability: same as the asynchronous motor structure, can be directly instead of asynchronous motor. Besides, it can be used for all kinds of bad working condition, how to low speed for a long time, frequency start, etc.

IE4 standard: it design novel structure and torque than the big volum , the volum is the same as power Y series motor shirnk up to 30% .Power factor than Y series motor hint of up to 15% , Motor is quiet and high overload at low temperature characteristices etc .

Q2: General inverter can match with variable speed electric motor directly to use?

No, the frequency converter must be support and drive non-inductive permanent magnet motor, And our MH40 series frequency converter can support it.

Q3: Does variable speed electric motor  meet what is international standard? 

Our Non-inductive permanent synchronous motor meet European IE4 energy consumption standard motor, And the level of protection is IP55. 

Q4: Compare with IE3, what is advantage of IE4? what is connection?

Basis on IE3, IE4 can save energy 5% to 10%, only Y connection.

Q5: Whether can directly wash variable speed electric motor  by water?

Non-inductive permanent synchronous motor is forbidden to wash by water.
