4, complex characteristics
four.1 By incorporating a “Γ”-shaped damping ring to the sound magnetic poles, the motor can supply a massive sufficient beginning torque, a pulling torque and a reduced starting up present, which can ensure the easy beginning and acceleration of the motor, and have a small impact on the electricity grid, and meet the user load specifications .
four.2 The use of new insulating components and insulation technologies, with super strong insulation and voltage resistance.
4.3 The motor adopts class F insulation, and the temperature rise is assessed in accordance to the temperature increase restrict value of course B insulation. It has a lengthy services daily life and a great ventilation technique, which makes the unit beneath numerous operating circumstances this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of every part does not exceed the allowable limit.
four.4 By way of exact calculation and examination, the construction of the rotor is decided. The large-electrical power motor adopts the integrated composition technology of shaft and choke to make the motor risk-free and reputable.
four.five The safety gadget is sophisticated and total.
four.five.1 The stator windings and bearings are geared up with temperature detection devices, which can detect, alarm and journey.
four.5.two Shutdown space heater with anti-condensation result.
Five, construction sort
five.one The construction of this sequence of motors is normally horizontal, and the cooling approach is a shut circulating air cooling method, which is found at the bottom of the motor. For additional-large-electricity motors, it is of box-kind framework and drinking water-cooled.
5.2 The motor magnetic content adopts high-high quality cold-rolled silicon metal sheet with large magnetic permeability and reduced decline, which improves the functioning performance of the motor and minimizes the operating expense of the motor. Rigid stator framework, the iron main is fixed on the supporting ribs of the frame in the circumferential path by means of the dovetail groove and compressed in sections with substantial pressure, and all the forces are transmitted to the foundation via the body, minimizing vibration. The damping ring and the magnetic pole adopt a unique fixing method to stop malfunctions caused by inadequate make contact with all inside conductive human body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening steps to make certain firmness and trustworthiness.
five.3 The stator winding is dealt with with VPI as a total dipping paint, which has substantial electrical functionality, mechanical power, insulation efficiency, dampness resistance and thermal steadiness.
5.4 The bearing is a sliding bearing with strain oil circulation, which is installed in a bearing seat made of solid metal. The sliding bearing has a spherical bearing that can routinely modify the heart. The interior area of the bearing is coated with a layer of Babbitt alloy to avoid energy technology Guide-tin eutectic occurs when the machine is working at substantial temperature. The bearings are insulated to stop shaft currents.
six. Situations of Use
