Y132M-4-7.5KW motor shaft outer diameter is 38mm.
Y series motors are fully enclosed self-fan-cooled squirrel-cage three-phase asynchronous motors, which are in accordance with the provisions of China's professional standard JB/T10391-2002, "Y series (IP44) three-phase asynchronous motor technical conditions", and are the basic series of products of national unified design.
Y series motors have high efficiency, energy saving, high blocking torque, low noise, low vibration, safe and reliable operation. The mounting dimensions and power level are in accordance with IEC standard and DIN42673 standard. This series adopts class B insulation, and the shell protection grade is ?IP44? The cooling method is IC411.
Y series motors are general-purpose motors, which are suitable for driving various mechanical equipments without special performance requirements, such as metal cutting machine tools, blowers, pumps and so on.
Expanded information:
1, the purpose of the application
A variety of The most widely used motor is the AC asynchronous motor (also known as induction motor). It is easy to use, reliable, inexpensive, solid structure, but the power factor is lower, speed regulation is also more difficult. Synchronous motors (see synchronous motor) are commonly used for large-capacity, low-speed power machines. Synchronous motor not only has high power factor, but also its speed has nothing to do with the size of the load and is only determined by the grid frequency. Work is more stable.
In the requirements of a wide range of speed occasions more often use DC motor. But it has commutator, complex structure, expensive, maintenance difficulties, not suitable for harsh environments. 1970s, with the development of power electronics technology, AC motor speed control technology is becoming more mature, the price of equipment is decreasing, has begun to be applied. Motor in the specified operating system (continuous, short-time operation system, intermittent cycle operation system) can bear without causing the motor to overheat the maximum output mechanical power is called its rated power, the use of the nameplate need to pay attention to the provisions.
Motor operation should pay attention to the characteristics of the load and the characteristics of the motor to match, to avoid flying or stopping. Electric motors can provide a wide range of power, from milliwatts to 10,000 kilowatts. The use and control of electric motors is very convenient, with self-starting, accelerating, braking, reversing, switching and other capabilities to meet a variety of operational requirements; motor efficiency is high, and no smoke, odor, not polluting the environment, and less noise.
Because of a series of advantages, it is widely used in industrial and agricultural production, transportation, national defense, commercial and household appliances, medical electrical equipment and other aspects. Generally when the motor speed regulation its output power will change with the speed.
2, structural characteristics
This series of motors can prevent water droplets, dust, iron filings or other debris from soaking into the motor interior, which is an energy-saving motor successfully developed in recent years in China.
3. Advantages and disadvantages
Reliable operation, long service life, easy to use and maintain, excellent performance, small size, light weight, small inertia, saving materials and other advantages.
4, the scope of application
Applicable to places that do not contain flammable, explosive or corrosive gases and no special requirements of the machinery, such as metal cutting machine tools, pumps, blowers, transportation machinery, mining machinery, mixers, agricultural machinery, food machinery and so on.
