Description:
It is well known that motors exchanges electrical to mechanical energy based on the magnetic field. Under the same loading conditions, compared with asynchronous motors, permanent magnet synchronous motors have less stator current and stator copper losses.
Thanks to the synchronous speed operation, rare earth permanent magnet synchronic motors(REPMSM) do not have slip between stator and rotor, also do not have copper losses and iron losses during stable operation, so the motors can have smaller fan and less ventilation losses.
XYT 12 pole series motors do not have reactive excitation current, so its power factor can be significantly enhanced to the limiting value1.0. In summary, compared with asynchronous motors, they have less losses and high efficiency (more than 4%~8%) , Especially running during 20%~120% rated load, XYT 12 pole series motors can keep high efficiency and power factor, the energy saving can be more obvious during light load.
Relying on so many years of practice, we develop XYT 12 pole series motor applied to pump, fan, compressor, textile machinery, metallurgy, petroleum, chemical and so on.

Meaning of type code
Tolerance
The permanent magnet motors can withstand 1.5times rated current for 2 minutes occasional over current.Also the motor can withstand 1.5 times maximum rated speed for 2 minutes when no-load.
According to IEC60034, the motors are designed can withstand 1.5times rated voltage and rated current for 2 minutes.
Pull-out torque
Pull-out torque is an important index to reflect REPMSM overload capacity. Pull-out torque of XYT series is in the range of 2.0~2.5 which ensure good overload capacity.
Under the condition of hot state and torque increasing, REPMSM can withstand specified Pull-out torque values(tolerance) for 15s.At this point , the voltage and frequency should be maintained in the rated value.
Coupling and Driving
XYT series motor is coupling with load through coupler or belt which is outside the scope of a motor manufacturer’s supply.
XYT series motor has single shaft ,we can produce double shaft if need. The second one can deliver rated power, but only can be drived by coupling.
