Product Description

Application
Applied to wound-rotor asynchronous motor overload smoothly soft start are which three phase current **0V,**0V,3KV,6KV,*2KV, power rating *5~****0KW.

Working Principle
The controlled of wound-rotor asynchronous motor rotor loop in series with the three-phase star connection liquid resistance, fluid resistance with starting motor and automatic , resistance will be stepless reduced within predetermined time, close to zero automatic excision, thus motor access rated current and maximum torque circumstances no impact on the smooth start-up.

Perforamance and features
1.Low starting current and constantly, no impact on the grid;
2. The starting current is less than 1.3 times of rated current,it can reduce the capacity of transformers
3. It can start under low voltage, power grid voltage can ensure motor run normally,then starting smoothly
4. It can start for 5~*0 times in succession
5. It smooth start up, little impact of mechanical stress, can protect the motor and transmission machinery effectively
6. Applicable to heavy load start
7. Simple structure, convenient installation and maintenance, high reliable
