Model: Efficient 75kw to 10000kw AC wound rotor motor soft starter
1) direct starting problem
motor will create big current shake if start directly ( 5-8 times more than rated current), it makes big strike for electic grid and loaded equipment, heavily reduce motor and equipment service life,Sometimes motor burnt .so,stepless smooth start and stop is neccessory

2) intelligent WYQ6 main function
1:smooth start, without shook to equipment, extend the using life,save equipment maintain cost
2:reduce start current, reduce temperature increasing of motor, largely extend the long of motor,
3:Full protect motor and loaded equipment

3)range of application:
suitable to heavy load soft starting of wound rotor asynchronous motor,
especially in industrial or mines with unstable or lower voltage

4)unique feature:
1: low starting current: the starting current is<= 1.3Ie(A)
2: simple structure, easy for install and maintenance
3:it can start under a lower voltage, for example, start in 5.5KV when rated voltage 6KV
4: Good uniformity, applicable to coiling motor soft s tarting under any load situation, specially for heavy load starting
5: Multiple protection function like starting overtime, over stroke, over temperature,etc
6: can started continuously for 5-10 times
7: adpts worm gear and worm lifter as the transformation tool, which is stable,reliable and noiseless

5)operating principle:
For wound rotor asynchronous motor, when the grid voltage and frequency are invariant,
the connection of the starting resistor to the rotor loop will reduce the starting current and get a larger starting torque.

putting special compound electrolyte into the rotor loop of the controlled winding motor as the liquid resistance, when the stator receive the signal of the motor starting, it will change the location of the electrolyte automatically, so as to reduce the resistance value gradually. when the resistance reached the minimum level, the sensor closed and motor rotor star connected directly, then the equipment start smoothly with a low current, large torque.
