Product Description

YJTG series variable-frequency adjustable-velocity asynchronous motor is the new era of variable-frequency adjustable-pace motor, which is designed base on the YJT variable-frequency adjustable-velocity motor. In the facet of electromagnetism style, we alter the rotor slots, the winding pattern, and the relationship, so that the motor allow to be provided by the transducer energy source. In the meantime, the design and style could promise the overload capability of the motor when higher frequency and it could preserve the identical with Y series motor, besides the size measurement, other dimensions is also same as Y series motor, This series motor is compelled air flow with the unbiased axial flow ventilator, which certain that the motor has excellent cooling functionality in the entire frequency range and the temperature increase is not in excess of that score.


The speed modulation method consisted of YJTG series variable-frequency adjustable speed three phase asynchronous motor and the frequency conversion installing, compares with other speed modulation way, the strength conservation effect is exceptional, the speed modulation efficiency is very good, the governor deflection is broad, the sound is reduced, the vibration is less, this motor can broadly apply in the light-weight business, the spinning and weaving, the chemical business, the metallurgy, device resource which want everlasting torque or change pace at the long lasting electrical power and the air blower, the drinking water pump which want strength saving pace modulation. It is valuable in developing automatic handle of the velocity modulation program.


The 4 poles motor of YJTG series electric motor conform to JB/T7118-2004 “the specification of the pace modulation system. Conversion variable velocity motor and power sources situation” and for other number of poles of electric motor conforms to IEC34-one and GB/T755.
