Frequency Converter - Frequency inverters - Variable Speed Drives - Oil Purification Manufacture Co., Ltd -

Frequency Converter

Frequency converter use rectifiers to convert ac power line electricity into direct current. Then inductor-capacitor filters smooth its waveforms and pulse-width-modulation inverters turn it into shaped ac power with a frequency of 2 to 12 Hz. This output is used to drive motors for constant torque or (with the help of encoders) to control motor speed. frequency converters are proliferating, as they save substantial amounts of energy during motor operation â�" an objective of increasing importance. Some frequency converters have built-in ac and dc brake functions to help transform kinetic energy from the application into braking power.

Frequency inverters

All the potential problems with frequency inverters and Motors on frequency inverters. This section will demonstrate to the student how to address and prevent these problems so that they do not create undesirable effects in the industrial system. Each of the above problems will be discussed with recommended solutions for each issue. The cost impact of these options will also be provided giving the student some degree of weighing the benefits of the options versus the cost of the consequence. The result of this seminar will allow the student to be able to properly apply a new frequency inverter with the required options in a plant providing years of trouble free operation. The objective of this frequency inverter training course is to build ...

Variable Speed Drives

Variable speed drives are ONLY for 3 phase motors, any method to speed control an induction motor. Variable speed drive with ONLY single phase input can drive capacitor start/run single phase motors. Variable speed drive operating from single phase have output voltage on each phase equal to input voltage. Higher capacity single phase motors with separate high torque/high current starting winding operated by centrifugal switch can not be used with variable speed drive. However a triac speed controller may work, as this could duty cycle the AC sine wave form. Try an off the shelf light dimmer and see if this can control the desired speed range of the fans. If this works, then some circuit research/lab work could produce a circuit that takes 0...
