Description
Technical field
The utility model relates to cement vertical mill with directly driving synchronous motor, is specifically related to Vertical Mill 2MW permanent magnet direct-drive synchronous motor.
Background technology
The Vertical Mill of cement drags mainly AC speed regulating motor and adds gear mechanical gear box Pulling, and along with cement vertical mill is in the extensive use of cement industry, user has higher requirement to equipment, ites is desirable to cancel gear and improve system effectiveness.The matching components such as the large-scale reductor of heaviness eliminated by low-speed big permanent magnet direct-drive motor; avoid complex structure that reducing gear brings, noise is large, reliability is low, efficiency is poor, safeguard the adverse effects such as frequent; and when meeting normal service, low cruise does not need the requirement of shutting down, and is the ideal substitute of variable-frequency motor and reductor.
Utility model content
The utility model provides a kind of Vertical Mill 2MW permanent magnet direct-drive synchronous motor, gear is not mechanically needed to drive cement mill, meet the requirement of the low-speed big needed for cement vertical mill, improve the efficiency of system, reduce the maintenance, repair intensity of workman, and motor is full-closed structure, further ensure the reliability of motor.
For realizing above object, by the following technical solutions: Vertical Mill 2MW permanent magnet direct-drive synchronous motor, comprise motor stator and the rotor of support and base inner, support upper and lower side is respectively provided with upper end cover and bottom end cover, it is characterized in that, support adopts water-cooling structure, little radiating ribs is welded with between water channel, thrust box and motor upper cover are structure as a whole, thrust bearing is arranged on thrust box, thrust bearing upper end supports runner plate, and permanent magnets is equipped with on rotor surface, and fan is equipped with in rotor end.
The utility model benefit effect: simplify the structure, eliminate gear, improve system effectiveness.Under operating condition, motor running is steady, and vibrate little, noise is low, and motor can operate steadily under ULF.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
As shown in the figure: 1, support; 2, motor stator; 3, rotor; 4, upper end cover; 5, bottom end cover; 6, thrust box; 7, thrust bearing; 8, runner plate; 9, permanent magnets; 10, fan.
Embodiment
Embodiment
As shown in Figure 1, support (1) is fixed with motor stator (2), motor stator inner sleeve has rotor (3), support (1) upper and lower side is respectively provided with upper end cover (4) and bottom end cover (5), it is characterized in that, support (1) adopts water-cooling structure, little radiating ribs is welded with between water channel, thrust box (6) and motor upper cover (4) are structure as a whole, thrust bearing (7) is arranged on thrust box (6), thrust bearing (7) upper end supports runner plate (8), permanent magnets (9) is equipped with on rotor (3) surface, fan (10) is equipped with in rotor (3) end.Bearings at both ends all has labyrinth seal.
Motor stator punching adopts DW470 cold-reduced silicon sheet, reduces iron loss, raises the efficiency; Adopt skewed slot technique during lamination, improve motor waveform and weaken motor cogging torque, substantially increasing motor slow-running characteristics; Stator winding adopts formed coil, improves the insulating capacity of winding; Support itself adopts water-cooling structure, is welded with little radiating ribs, has both added the heat-sinking capability of motor, strengthen again support intensity between water channel; Permanent magnets is surface-mount type, and angle is repaiied in design, effectively improves motor waveform; Motor internal rotor tip is equipped with fan, greatly strengthens the exchange heat between end winding and support.
