Description

   

    The newest generation of ECM series motors are designed with advanced electronic control technology, make the motor efficiency greatly increased.Compare with other series moters,ECM motors display an obvious advantage in energy saving, saving up to 70%. It can greatly reduce  the electricity cost for motor operation and carbon dioxide emissions. Not only that, due to the heating of ECM series motors themselves are  very low, it would lead to the entire refrigeratton system works more efficient and make motor running more stable and reliable.

 

Main features

• High safety class 

ECM motors adopt thermoplastic for housing and the protection level has achieved class II, therefore the earth     conductor  will be unnecessary and the cost will be reduced.

• High protection class  IP65

Enclosed motor design will have a better moisture-proof effect and make It possible to work in the high humidity and dust environment

• High reliability

The dual-chamber design(Patented) leads the motor can be effectively separated from electronic control area in order to avoid dust and  humidity enter in to the cavity of control board.Regarding oomponencs selection. We cooperale with the world' s leading suppliers in order to offer the best quality.Our R&D department has done various of tests to simulate the real working conditions of the fans (such as temperalure, vibration, lifetime, etc.)  in order to make the design more reliable.All of our products are designed with high quality and long lifetime We work over everypart of our ECM motor, carefully cloose devices and materials, together with suitablecontrol board and intelligent protection system, our motors had achieved a life expectancy over50,000 hours in continuous working conditions.

• Constant speed control

constant speed control means the motor mintains a constant speed across a wide range of vollages and fan blades, it will help the coolng system work  properly and avoid the noise generated by the fluctuation of motor speed

• Reverse on start

ECM motors an run backwards automatically when start-up through pre-set of the programme This important functlon can help to blow away dust from the heat  exchanger of the condenser in order to make the refrigeration system more efficient. Further more, there is no extra signal control needed to achieve this function.

• Reverse on demand    

With this feature you can determine the time and duration of reverse running. For example, during the compressor "off" period or Ihe defrost cycle, you can start reverse running to blow away dust.Moreover, without needs of extra relays can save more cost.

• Two speeds

 ECM motom can run both in high-speed and low-speed through pre-set programme by Supplier, this ruction would be very useful in the relrigeration system  application which has daytime and nighttime modes. thus to save more energy and reduce the noise.

• O-lOVdc Full speed control 

 ECM 0-10V step-lass speed regulation motors include AC and 24VdC power supply.operators can control the O-10Vdc to  control the signal light to  process step-less speed regulation It will intelligently control the cont rol system and result in better energy saving effect.
