Y series three-phase asynchronous motor features: Y series three-phase asynchronous motor not only meets the matching needs of various departments of the national economy, but also improves the interchangeability of similar products at home and abroad, greatly facilitating the matching and maintenance of imported equipment. Y series three-phase asynchronous motor can be divided into two basic series: IP23 (protective type) and IP44 (closed type) according to the different protection grades of the outer casing. Now the big blue motor small series focuses on IP44 (closed type). The characteristics of asynchronous motors.
The Y series (IP44) three-phase asynchronous motor has the following good performance and structural features:
(1) The efficiency level is high. The Y series (IP44) small three-phase asynchronous motor maintains the high efficiency of the J02 series motor, and its efficiency weighted average is 0.413% higher than the J02 series, reaching an international level. As the efficiency of the motor has increased, it has brought huge economic benefits to the society.
(2) The starting performance is good. Y series (IP44) full series of motors have a stall torque of 33% higher than the average value of J02 series motors. The starting torque reaches the level of JQ02 series high starting torque motor, and the minimum torque is guaranteed to be 0.8 times of rated rotation. Above the moment, and most of them reach or exceed 1 times the rated torque. Therefore, its starting performance is very good, and the load start is also very smooth.
(3) Low noise and low vibration. The Y series (IP44) three-phase asynchronous motor is specified with sound power noise standard, and is divided into level 1 and level 2 according to the noise limit for the user to select. Since the series uses motor-specific bearings, the running noise is greatly reduced. The measured noise is lower than the actual level of the J02 series by about 5 → 10 decibels, and the vibration is also greatly reduced compared with the J02 series motor.
(4) Better protection performance. The structural design of the Y series (IP44) three-phase asynchronous motor has met the protection requirements for external solid objects and splashing water, which can effectively prevent the damage of foreign objects to the motor and the human body.
(5) The operation is reliable and has a long service life. The Y series (IP44) three-phase asynchronous motor windings are made of Class B insulation. When the altitude does not exceed 1000 meters and the temperature of the cooling air does not exceed 40 °C, the temperature rise limit (resistance method) of the stator winding of the motor does not exceed 80K. Therefore, except for a very small number of specifications, motors generally have a temperature rise margin of 15K or more. Larger temperature rise margins extend the life of the motor and increase the reliability of the motor.
(6) Beautiful appearance. The shape of the main structural components such as the end cover, junction box and hood of Y series (IP44) three-phase asynchronous motor are more beautiful and generous than traditional old products. The full range of motors is 15% smaller than the J02 series, and the average weight is reduced by 12%.

CA Temporary Fence Introduction:
Temporary Fence is also called
Construction Fence,Removable Fence and Portable Fence. This type was
very popular in Canada, the United States, and some other America
countries.
It is quick to be set up and easy to move and is ideal for restricting
access or containing a site and is commonly seen at construction sites,
public events, as a dog run, or anywhere crowd control is important.
It offers the benefits of affordability and flexibility.
