TAW Series Increased Safety Brushless Excitation Synchronous Motor

3 Structure description

The overall structure of this series of motors is a box structure, and the base, outer cover, bottom plate, and bottom cover are welded by steel plates. The main motor is an independent cavity. The AC exciter and the rotating rectifier disk form another independent cavity. The two cavities share an air path system. The AC exciter and the rotating rectifier disk are located outside the non-shaft extension end-bearing, and the overall shape is Beautiful and generous.

The magnetic materials of the motor and the exciter are made of cold-rolled silicon steel sheets with high magnetic permeability and low loss; the damping strip and the magnetic pole core adopt a special fixing method to prevent starting sparks; all internal conductive body connections, fasteners, supports and rotation The screws on the body are provided with anti-loosing measures to ensure firmness and reliability, and avoid sparks and arcs; reliable anti-corona measures are adopted for the stator winding to increase the corona initiation voltage; the insulation system between the winding turns and the ground is strengthened to improve the withstand voltage of the motor Reliability, the main motor and AC exciter winding are treated with VPI as a whole, which has high electrical performance, mechanical strength, insulation performance, moisture resistance and thermal stability.

The high-voltage junction box protection grade is IP55, the wiring cavity is large, the junction box is on the right side of the motor (as viewed from the shaft extension), when the motor power is greater than 2000kW, a magnetic balance current transformer is installed in the motor main junction box, and all auxiliary junction boxes They are all on the right side of the motor (viewed from the shaft extension).

Seated spherical sliding bearings are used. For motors with stator core outer diameters of 1730mm, 2150mm, and 2600mm, oil ring self-lubrication or compound lubrication can be used. For motors with stator core outer diameters of 3250mm, forced lubrication is adopted, while preventing Measures for shaft current generation.

The monitoring measures are complete. Six platinum thermal resistors pt100 are embedded in the motor winding slots, and each bearing is equipped with two platinum thermal resistors pt100, which can be displayed on site or remotely monitored; anti-condensation heaters are installed to prevent condensation during shutdown; A water leakage detector is installed to send out a signal when the cooler leaks.

It has a variety of measures to improve the safety of explosion-proof, rotating rectifier element, resistance element with large capacity and high reliability, and obtained the component explosion-proof certificate; the brushless excitation system ensures accurate starting and excitation, stable process, no vibration, and no impact.

An observation window is provided on the motor housing to facilitate observation of sparks, voltage, corona, etc.

The rotating rectifier is changed from the traditional one located between the motor and the exciter to outside the exciter, which is convenient for maintenance.
