control of induction motors and permanent magnets (BLDC) with tion+ drive

Inverter and drive + tion has the ability to control all types of air conditioner motors, the most important of which are induction electric motors and permanent magnet electric motors, especially PMSM and BLDC. Induction motors, which are older examples in the air conditioning industry, are easily controlled using this drive, and the user and, of course, the controller equipment can control its rotation speed and thus the air flow.

BLDC motors in air conditioners and its advantages

But with the advancement of technology and the advent of permanent magnet motors that have a higher energy density and thus reduce energy consumption, it flourished. This higher energy density makes PMSM and BLDC motors also require less space, which is a very ideal option considering the modern apartment life where space occupied by all objects, including air conditioning systems, is very important. 

But these are not the only advantages of using a BLDC motor in air conditioners and other cooling and heating equipment!

The BLDC motor can be coupled to the impeller without the need for a belt, and in addition to reducing the noise caused by the operation of these systems, it also increases their lifespan due to the reduction of friction.

Until a few years ago, engineers faced the challenge of controlling the use of permanent magnet electric motors. To control these types of motors, we need to know the exact position of their rotor, and obtaining this information required sensors or more intelligent methods. Today, qualified electrical engineers can use up-to-date methods and sensorless technology to detect and control the position of the rotor, even without the need for a sensor. The tion+ drive, designed and built by the experienced engineers of Electromotor Aria (EMTtech) Company, can easily control all types of permanent magnet motors in addition to single-phase and 3-phase induction motors.

The tion+ electric drive with permanent motion magnet motor has achieved the IE5 energy class and the INSO 3772-30-1-3 BLDC standard has the highest energy efficiency class in the world. This technology has created a great change in reducing the energy consumption of the country’s air conditioning industry.

In addition, this product has the ability to work in a humid environment full of noise and vibration inside the air conditioner, observing all the necessary standards, and it handles this task well and continues to work even in the worst conditions with a power factor of 0.99. 

Body design and case drive tion+ all the subtleties to be coordinated with all applications of air conditioning systems that can be easily installed on the fan or body of the user structure.

Intelligent control of BLDC motor drive

wait. All we have said so far is not the only benefits of EMT’s BLDC drive. The tion + drive can be synchronized with intelligent systems such as digital thermostats such as Expono, Honeywell, Danfoss digital thermostats, etc., and depending on the command line it receives from them, air conditioners, duct splits, fan coils or other types of equipment Control air conditioning.

In addition, the bldc tion+ drive connects to all sensors and operators of air conditioning systems such as water level sensors, pumps, temperature sensors and drain valves for further synchronization with the digital thermostat and HMI user interface.

Communication with control systems

In order to reduce the costs and complexities of connecting the Expono digital thermostat and the HMI user interface, unique Power Line Communication technology has been used to sync the Expono thermostat and the tion+ drive together with a minimum of hardware and only two signals.

This technology makes it easy to operate and adapts the expono thermostat and tion+ drive set to all air conditioning applications. The tion+ drive also has the ability to coordinate and operate with a wide range of thermostats and Human Machine Interfaces common in the market by providing common communication platforms such as: RS-485. Utilizing this technology, reliable and stable two-way communication between the drive and HMI is easily possible even at very long distances and noisy environments.
