Brushless Central starter WSQ3 brushless the Central starter: JR, JZR, YR, the YZR three-phase wound rotor AC induction motor (also known as slip ring motor). Since its rotor external resistance or reactance, high power factor and high starting torque at startup, while a smaller starting current. Therefore, in the fields of metallurgy, machinery, chemicals, mining, building materials commonly used in such a motor to drag the device. However, due to the slip ring, carbon brushes, brush box, short-circuit ring is mounted on the shaft of the motor parts, they are in the control box time relay, AC contactor, frequency sensitive rheostat and other electrical components to form a complete secondary loop system as this motor starting or shorting device, the motor running, prone to failure: long-term carbon brush and slip ring friction, must be frequently changed. Carbon brush and slip ring friction prone to spark some places can not be used. Brush and slip ring friction increases the contact resistance, causing excessive temperature rise. Conductive powder brush and slip ring friction accumulated inside of the suction motor, the most burned the motor and a big hidden. The time relay out of control, easy to burn the AC contactor and frequency sensitive rheostat. Controlled brushless the vacuum motor starters for you to solve this problem. Meaning and advantages of the product model: the starter is not only the traditional wound rotor motor to get rid of the large and complex starting system, but also to solve the eddy current loss, leakage reactance starter fever a few of the most important problems. The starter is to install a pressure-relief device for synchronous operation of the motor rotor, motor speed and inertia effect, set the vacuum short tap, the shorting switch internal vacuum interrupter design, to eliminate from climbing electric starter caused burning phenomenon occurred. When the motor reaches the rated speed, without the use of the starter, the the shorted device will coil winding automatic disconnect, not only saves energy, but not heat coil winding to ensure the stable operation of the starter. Its advantages are: remove the slip ring, carbon brushes, brush box and short-circuit ring, remove the secondary loop systems in the frequency sensitive rheostat, AC contactors, time relays and other components, in the brushless motor loop operation based on the real to maintain the original operational characteristics of the motor, which prolong the life of the motor at the same time, also to ensure that the service life of the starter itself. Controlled brushless vacuum motor starter is bound to excellent starting performance, low price, power supply and load adaptive capacity, small size, energy efficiency and running easy maintenance, etc., to obtain a wider range of applications. The Brushless the starter ring Overview: brushless starter ring is a means of overcoming the shortcomings of the wound rotor induction motor with a slip ring, carbon brushes and complex starting device, while retaining the winding motor starting current in WSQ3, starting torque and the advantages of starting equipment. Where the original resistance starter, reactors, frequency sensitive rheostat, liquid rheostat starters, soft starter starter JR, JZR, YR, the YZR three-phase wound rotor AC induction motor (variable speed, except with into the camera) can be selected Brushless starter ring "more
