Product Details

Brief Introduction

The main power terminal box of the wound rotor induction motor has three terminals and six terminals (our company's high-voltage motor is commonly used as three terminals, if you need six terminals, please specify; Box type low-voltage motor for six terminals), three terminals marked U, V, "; The six terminals are labeled U1, V1, W1, U2, V2, and W2; If the motor has a central terminal box, the three terminals of the central terminal box are marked U2, V2, and W2.

 

High voltage motor Motors below 2000kw are provided with a main power junction box. In addition to the main junction box, the motor of 2000kw and above is provided with a secondary junction box on the opposite side of the main junction box (that is, from the point of view of the shaft extension, one junction box on the left and right), and the star point of the stator winding is not connected to the inside of the motor, but is led to the secondary junction box, which is convenient for the user to connect the current transformer and protect the motor. Our company does not provide current transformer when the user does not specify. In the user's special requirements to provide current transformers, the two sides should negotiate with each other, choose the same model of current transformers, so that they match each other.

 

When wiring, the alphabetical order of the line end mark (U, V, w or U1, V1, W1) is the same as the alphabetical order of the phase sequence of the power supply (A, B, C), and the spindle extension end is regarded as clockwise: any interchange of the two-phase connection, the wound rotor induction motor can be changed to counterclockwise rotation.
