Product Introduction

Synchronous motor excitation type

As a designated manufacturer of rectifiers by the former Ministry of Machinery Industry, we specialize in the production of electrolytic and electrochemical rectifiers. We have numerous production achievements and rich manufacturing experience in the electrolytic copper industry.

KGLF11-450A/170V

Synchronous motor

The KGLF11 thyristor excitation device is suitable for constant excitation of synchronous motors starting under heavy or light loads, and is also applicable for excitation of small generators. This device has the following features:<br /> 1.The rotor circuit of the synchronous motor adopts a three-phase fully controlled rectifier bridge fixed excitation circuit, maintaining the inherent starting characteristics of the synchronous motor.<br /> 2. There is no direct electrical connection with the stator circuit of the synchronous motor. Therefore, the synchronous motor can be designed as high-voltage (3-6-10KV) or low-voltage (380V) according to the conditions of the power grid, and full-voltage starting or reduced-voltage starting is not restricted.<br /> 3.When starting a synchronous motor at full voltage, when its speed reaches sub-synchronous, excitation can be put into operation with a rotor slip of 5% to 4% in the forward polarity to drag the synchronous generator motor into synchronous mode. Alternatively, excitation operation can be delayed for a certain period of time after the motor is connected to the power grid.<br /> 4. For a synchronous motor starting with reduced voltage, when the rotor speed reaches about 90% of the synchronous speed, the reduced voltage starting reactance or resistance is automatically disconnected, and the full voltage is automatically engaged to accelerate the start-up of the synchronous motor to sub-synchronous speed. The excitation is carried out in a stepwise manner with a slip of 5% to 4%, thus pulling the synchronous motor into synchronous operation. <br />5. When the grid voltage fluctuates, it features negative voltage feedback and automatically maintains a basically constant excitation. When the grid voltage drops to a certain percentage, it suddenly intensifies the excitation, with a strong excitation time of 10 seconds or 40 seconds.
