Hur fungerar ec motor
When the rotor moves near one coil, the next coil will be energised. Mycket förenklat kan man se det som en likströmsmotor som man har vänt ut och in, där man snurrar på magneten och låter kopparlindningen stå still. The motor needs to be supplied with AC voltage and a DC voltage signal to operate. A sensor determines the position of the rotor, and based on this information, the controller decides which coil to energise.
It is essentially a permanent magnet, brushless DC motor that incorporates on-board electronics. The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external . The stator is driven by electronic switches controlled by a microcontroller.
Fig 1. The initial development of EC motors can be traced back to s. The answer is, electronic controller.

Today the popularity of EC motors continues to increase, mainly because of a number of benefits being widely recognised. 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. The power will not be wasted because the electronics control the stator. Here we will just list a few of the most important benefits for you to understand why industry professionals tend to tap on EC technology more than ever.
The decisive advantage of motors with EC technology compared to conventional asynchronous motors is that EC motors can achieve a better efficiency than AC equivalent. Now you might have some intriguing doubts in your mind: How do we know which coils to energise and when to energise to get a continuous rotation from the rotor? The initial development of EC motors can be traced back to s. When it comes to motor designs, engineers have three main types of options — alternating current AC , direct current DC and electronically commuted EC motors.
The added electronics allow an EC motor to combine the best features.

En borstlös motor (även kallad borstlös likströmsmotor, EC-motor eller BLDC-motor) är en vidareutveckling av den traditionella likströmsmotorn (även kallad DC-motor). The operation of an EC motor is based on the force interaction between the permanent magnet and the electromagnet. EC stands for E lectronically C ommutated. An EC .
Fördelar & Nackdelar EC-motor: Fördelen med en EC-motor är att den . The EC motor. The answer is, electronic controller. How does an EC motor work? Motor applications are deployed across a multitude of industries where motion-control functions are required.

This process is repeated and the rotor continues to rotate. By apply DC power to the coil, the coil is energised and become an electromagnet. The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design.
In this article we are going to provide a comprehensive introduction to EC motor. See more. A sensor determines the position of the rotor, and based on this information, the controller decides which coil to energise.
Secondly, EC motors provide better performance and controllability with speed control electronics. Resources Members. Den stora skillnaden är att en AC-motor drivs av växelström till skillnad mot EC-motorn som drivs av likström. EC motors are the brushless electric motors that designed with permanent magnets on the rotor and on-board electronics to control the voltage and current applied to the motor.
When energy cost comes into the picture, selecting the most energy efficient motor design plays an important part.

When one coil is energised, the opposite poles of the rotor and stator are attracted to each other. So how does it work? ebm‑papst, the pioneer in advancing EC technology, brought the world’s first EC/DC compact fan into the market in Today the popularity of EC motors continues to increase, mainly because of a number of benefits being widely recognised.
When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions. The rotor of an EC motor is a permanent magnet and the stator has a coil arrangement.
