DVM Motor Solutions

Electronically commutated (EC) motors are highly efficient, programmable, brushless DC motors utilizing permanent magnet rotor and a built-in inverter. Basically, it is a DC motor (in a DC motor the mechanical commutation switches the direction of the current) with a built-in VFD (Variable Frequency Drive) and a DC to AC Transformer.


EC Motor Solution

In EC motors, the mechanical commutation and the brushes are replaced by an electrical commutation. EC motors are extremely efficient, especially at reduced speeds compared to traditional motors. Also, they have a built-in speed controller eliminating the need for a seperate VFD.

EC vs Traditional Motors

With an EC motor the electronic circuitry stands in lieu of the traditional mechanical commutation; meaning the right amount is being supplied in the right direction at exactly the right time providing precise motor control. EC motors are very valuable for small motor sizes, where a variable frequency drive (VFD) is not cost effective. They are also great for installations where constant design flow is required because the motor design is more efficient.

What is ECM Technology?

EC Technology stands for Electronically Commutated and combines AC and DC voltages, which is essentially a fan with a brushless DC motor, brining the best of both technologies: the motor runs on a DC voltage, but with a normal AC supply. The EC motor incorporates voltage transformation within the motor. The non-rotating part of the motor (Stator) is extended to make room for an electronic PCB (Printed Circuit Board) which includes power transformation AC to DC, as well as the controls
