What is an Electronically Commutated EC Motor?

An electronically commutated (EC) motor is designed to run on an alternating current (AC) power supply, but it in fact bears a closer resemblance to a direct current (DC) motor. It is essentially a permanent magnet, brushless DC motor that incorporates on-board electronics. The added electronics allow an EC motor to combine the best features from both AC and DC motors, and then improve on them. For this reason, an EC motor is in a category of its own.

By utilizing this technology, EC fans are highly efficient and pay for themselves through lower operating costs and extended service life. They also provide many operational benefits that are often overlooked.

EC motors use permanent magnets and electrical windings to generate their magnetic fields, in a similar fashion to brushed DC motors. However, as their name suggests, they achieve commutation electronically rather than mechanically. This is only possible by incorporating on-board electronics within the housing of an electronically commutated EC motor.

The on-board electronics include a rectifier that converts the AC supply to DC. An integrated controller then directs the right amount of current, in the right direction, at the right time, through each of the windings. This develops magnetic poles in the stator, which interact with the permanent magnets in the rotor.

The position of each magnet is determined by using Hall effect sensors. The appropriate magnets are attracted, in sequence, to the magnetic poles in the stator. Simultaneously, the rest of the stator windings are charged with the reverse polarity. These attraction and repulsion forces combine to achieve rotation and produce the optimal torque. Since this is all done electronically, precise motor monitoring and control are possible.

Advantages of an Electronically Commutated EC Motor

Energy Efficiency: EC motor efficiency is often above 90%, allowing EC fans to consume up to 70% less energy, when compared to conventional fans. Running an EC fan at 80% speed saves nearly 50% of the energy.
Ease of Control: By continuously monitoring motor functions and automatically adjusting the control input, high efficiency is maintained throughout the operable speed range. EC motors are often capable of being turned down to 20% of full speed, while still maintaining 85% efficiency. Sensors that produce a 0-10V signal provide speed control without the need for a complex variable frequency drive.
Versatility: EC motors are capable of exceeding rated speeds. This allows fans with EC motors to achieve higher capacity within a smaller fan package.
