Energy-efficient
Intelligent and efficient, green and energy-saving, with large starting torque and strong overload capacity.
High system integration
The permanent magnet motor and inverter are integrated innovatively and innovatively, simplifying the drive configuration design and making the drive layout more flexible; Advanced circuit topology design for higher power density.
"Zero" frequency conversion output distance
The system integration is not affected by the output distance of the frequency converter, and the influence of long-distance power supply voltage spikes on the insulation life of the motor is completely eliminated.
Low requirements for cable use and less line interference
the all-in-one power supply does not need to shield the cable, there is no need to consider the radiation interference on the cable path, and the cable cost and laying cost are lower.
Small floor space and simple construction
save the inverter layout space, output side reactance filter, and no need for cable laying, short construction time and low cost.
