product feature

Integrated simple design

• Integrated design of motor and inverter: compact electrical structure, high reliability, easy installation and maintenance, local operation and control.

• Independent cooling duct: inverter and motor unified heat dissipation, independent air duct design, the inverter does not need to add additional fans, effectively reducing noise.

Excellent performance

• Silence: built-in intelligent vibration observation model, dynamic identification of system resonance frequency, automatic planning of frequency converter operating interval, effectively avoiding the system resonance caused by noise pollution and mechanical damage.

• Smooth operation without fluctuations: the combination of patented beat suppression technology and highly reliable film capacitor design reduces torque pulsation, ensures stable operation of the system, extends product life, and reduces the size of the whole machine.

Reliable reliability and protection

• Scientific layout and excellent manufacturing process: strict selection of high-quality components, scientific modular layout, IP55 high protection level design.
