Reducing servo drive EMI noise by Elmo’s FASST technology
- Any application
Electromagnetic interference (EMI) noise is defined as unwanted electrical signals that produce undesirable effects in a control system.
The EMI noise affects the servo drive electrical circuit by triggering electromagnetic interference to the motor power switching process (PWM). The motor strives for fast switching and causes the drive to rapidly changing the electrical current phases and produce high EMI.
Elmo’s FASSTechnolgy keeps the process “soft” and with no stress to the power device. The results are low EMI.
Our unique Fast and Soft Switching Technology significantly reduces the EMI typically created by PWM drives.
In most applications, with Elmo servo drives there is no need for additional external means (such as filters) to meet EMC requirements.
