The most powerful and overall models of three-phase electric motors are represented by the AIR 355 series, which uses an electric network with an alternating current of 50 Hz and has a rotation axis of 355mm.
Application
With a power of 110kW or more, the AIR 355 electric motors are designed for use in various industries to drive various mechanisms that require a constant rotational speed under variable loads and high power.
Device
The outer shell of the model body can be made of cast iron or have an option with an aluminum frame and cast iron shields to ensure high heat transfer. The housing design protects the engine from dust and moisture according to IP55 class.
These asynchronous electric motors have received a copper stator winding, which is characterized by increased resistance to high voltages. The winding in the stator is laid in special phase niches, which are connected to each other in the form of a "star" or "triangle" and a simple transfer to the desired terminals provides power from the 380V or 660V mains.
Features
To ensure the optimal functioning of AIR 355 electric motors, it is recommended to adhere to the S1 operating mode (long-term operation without frequent switching on and off). With a high rotation axis (355mm), these models can achieve an efficiency of 95% at maximum rpm.
Also, Class F protection is provided to protect power grids from overloads. And the engines themselves are protected from short-term mechanical overloads and have the ability to maintain constant rpm under variable load.
Modifications
The AIR 355 series has the largest representation in the model range and is announced by units with external dimensions of 1565x710x1010mm, which differ in power and speed of rotation of the working shaft. The line includes modifications:
- Air 355 M2 with a capacity of 315kW, 3000 rpm and a weight of 1480kg;
- AIR 355 M4 with a capacity of 315kW, 1500 rpm and a weight of 1860kg;
- AIR 355 M6 with a capacity of 200 kW, 1000 rpm and a weight of 1750 kg;
- AIR 355 M8 with a capacity of 160kW, 750 rpm and a weight of 1640kg;
- Air 355 M10 with a power of 110kW, 600 rpm and a weight of 1550kg;
- AIR 355 S2 with a capacity of 250kW, 3000 rpm and a weight of 1550kg;
- AIR 355 S4 with a capacity of 250kW, 1500 rpm and a weight of 1550kg;
- AIR 355 S6 with a power of 160kW, 1000 rpm and a weight of 1550kg;
- AIR 355 S8 with a capacity of 132kW, 750 rpm and a weight of 1570kg.
For mounting engines of this series, there are three types of execution for each model, providing installation on paws, on paws and with flange connection or only with flange fixation. Some of the heaviest AIR series electric motors that you can buy.
