Product Description

The YGT series three phase permanent magnet synchronous motor is a rare earth
PMSM which could operate smoothly without resistive loss of rotors, thus reducing
The general loss by 20% to 30% and in result improving its efficiency by 3% to 4%.
The PMSM could be used to replace the general induction motor and synchronous
Motor and operate well under various working conditions, especially on the conditions
Where the loads change periodically, such as in the pumping units used in oil exploitation.
Also, this electric motor is much more energy-saving than the induction motors,
Enjoying a desirable power saving rate of 10% to 30%.
? Features

1. High Starting Torque, High Overload Capacity
Our three phase permanents magnet synchronous motor has a higher starting torque, a greater
Overloaded capacity, and a reduced installed power. Its torques and overload capacity could
Be averagely one to two or even three power levels higher than those of the asynchronous
Motors. The ratio between the maximum starting torque and rated torque could be 3.25.
Also, this three phase synchronous motor could start smoothly;

2. High Operating Efficiency
There is no slip loss during the motor's operation. Meanwhile, as the magnet field is formed
By permanent magnets, neither the reactive excitation current of the stator is needed nor is
There any resistive loss of the rotor. That is what the induction motors are incapable of.
Therefore, the operating efficiency of the permanents magnet synchronous motor is always
3% to 4% higher than that of the induction motors;

3. High Power Factor
As the permanent magnets serve as the excitation source, the power factor of the permanent
Magnet synchronous motor could reach 0.98 during full-load operations. When the load factor
Reaches 40% to 50%, the electric motor's power factor could exceed 0.8.
When the load factor is higher than 50%, the power factor would increase a lot, even beyond
The rated power. Hence, Compensating equipment are reduced, increasing economic benefits;

4. Unique Design, Long Service Life
The rotor structure of this rare earth motor is quite unique in that there are cooling circulation
Channels within the structure which are delicately designed to lower the temperature raise of
Rotors and ensure a perfect working temperature for the permanent magnets, thus stabilizing
The magnetic field and extend the, magnets' lifetime.
Also, the embedded permanent magnets within the permanent magnet synchronous motor
Are replaceable. So once their magnetism degraded or thoroughly lost as a result of a burnt motor
In an accident. It's very convenient to remove the magnets from the rotors for re-magnetization
Or replacement. Customer could also save the costs of repair and maintenance;

5. Strong Interchangeability, Easy Maintenance
The rare earth synchronous drive unit is equipped with the same motor frame as that of the
Y series and Y2 series motors. Its external dimensions and installment dimensions also consist
With those of the Y and Y2 motors. Given this fact, the YGT synchronous motor, Y motor and
Y2 motor are interchangeable with each other and share similar maintenance requirements.
Therefore, it's quite easier to replace other induction motor with the YGT motor.
To be short, this series electric motor manufactured by our factory enjoys a wide range of
Rated powers from 5.5kw to 45kw. The input voltages are AC 380v, 660v, or 1140v, with the
Frequency of 50Hz.
