Product Detail

WSTF series is a new integrated motor designed by Wonder, which combines high efficiency IE5 permanent magnet synchronous motor with integrated driver. The motor performance conformsto IEC TS 60034-30-2 ED.1, 2016-12. Wonder Inverter-integrated PM motors are suitable for longtime running and fluctuating load conditions such as water pumps, fans, fluid machinery, etc.


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.


Reliability and protection

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

• Multiple protection: with comprehensive overcurrent, overvoltage, undervoltage, overload, phase loss, overheating, and short circuit protection capabilities to ensure the safe operation of products.


Specially optimized design for pump applications

• High efficiency and energy-saving control strategy: advanced vector control algorithm and energy-saving hibernation strategy are adopted, and the overall efficiency reaches the national level of energy efficiency.

• Water supply special function: built-in efficient constant pressure control, multi-intelligent energy level link control function, with high and low water pressure protection, water shortage protection, anti-freeze protection, water shortage reset, burst pipe detection, and other complete water supply system special protection capabilities.
