4.Xima YX series 6KV / 10KV large high-efficiency high-voltage motor model description
The motor model is composed of the product code and the specification code in order according to the provisions of GB4831. The product code is represented by the motor series code, which has the following meaning:
YX 500- 4 4-pole center height 500 (mm)
Squirrel-cage rotor high-efficiency three-phase asynchronous motor V. Xima YX series 6KV / 10KV large high-efficiency high-voltage motor structure description
YX is the basic series, the protection class is IP23, and the cooling method is IC01. Remove the protective cover on the top of its base and install different protective covers (or coolers) to derive motors with various protection levels and cooling methods, such as YXKS (air-water cooling), YXQF (climate protection), YXKK (air-air cooling) series motors.
The motor adopts the internationally popular box-type structure, and the frame and end cover are made of welded steel plates. It has good rigidity and light weight. After removing the protective cover (or cooler), you can observe and touch the inside of the motor, which is convenient for the installation of the motor, service.
The stator adopts external press-fitting structure. The stator winding adopts F-class insulation material and anti-halo material. The winding ends are fixed by special binding technology, which is firm and reliable. The entire stator is treated with vacuum pressure impregnation F-level solvent-free paint (VPI). As a result, the motor has excellent and reliable insulation performance and moisture and impact resistance. This series of motors H355 ~ H630 all use magnetic slot wedges. Orders that require non-magnetic slot wedges are not accepted.
Most of this series of motor rat dragon rotors use copper bar rotors. Rat dragon copper bar rotors adopt advanced and reliable welding processes and are fastened in the slot. Reliable operation, a small amount of cast aluminum rotor.
There are two types of bearings: rolling bearing and sliding bearing, which are determined by the power and speed of the motor. The basic type of protection is IP44. If the motor has a higher protection level, the protection level of the bearing will also increase.
Motors with rolling bearing structure have non-stop refueling and draining devices, and are equipped with special refueling tools.
The main outlet box is a sealed structure with protection class IP54. Generally installed on the right side of the motor (viewed from the shaft extension end), and can also be installed on the left side according to user needs. The cable entry holes of the outlet box can be turned up, down, left, and right. There is a separate ground terminal inside the box.
The two-pole motor bearing adopts rolling bearing (H355 ~ 450) and sliding bearing (above H500) structure. The sliding bearing adopts oil ring and pressure oil circulation compound lubrication method.
The internal and external fans of this series of motors are directional, and the motor can only rotate in the specified rotation direction.
The air-to-air cooling structure of the two-pole motor external fan (cooling method IC616) requires a low-voltage power supply.
6. Start of Squirrel Cage Asynchronous Motor (YX, YXKS, YXKK Series)
The rotor of the squirrel-cage asynchronous motor uses advanced calculation technology to calculate the starting temperature rise and stress of the squirrel-cage rotor. To prevent the motor from being damaged early due to excessive starting load.
The user is recommended to check: (1) the moment of inertia of the rotating part of the driven mechanical equipment (converted to the motor speed) should not exceed the value of (load J) in the technical data table; (2) the user's power grid should ensure that the motor is in the starting process The voltage of the motor terminal in the motor is not less than 85% of the rated voltage; (3) The resistance torque characteristic of the driven machine is the resistance torque characteristic of pumps and fans.
Under the above conditions, the motor is allowed to start twice in the actual cold state, and the motor is naturally stopped between the two starts; or it is started once in the hot state of the motor. Restarting the motor beyond the above limits should be stopped after 1 hour.
If the moment of inertia of the mechanical rotating part of the motor drive exceeds the value of (Load J) in the technical data sheet, or the motor is required to be started frequently, or the motor may be started with a heavy load, please contact the manufacturer in advance for special Designed to ensure reliable starting of the motor.
The air-to-air cooling structure of the two-pole motor external fan, the main motor needs to be started after the cooling fan is started.
