As we know, VFD drive play a major and very important role in nowadays. It can help the world life more comfortable and sustainable. Variable Frequency Drive for short can called VFD, other names can also called AC Drive, Frequency Inverter, Frequency Converter, adjustable speed drive, adjustable frequency drive, variable speed drive and microdrive. A VFD drive is a type of motor controller that d...

AC drives or Variable frequency drives control speed, torque, acceleration, deceleration, and rotation direction of AC motors. AC drives save energy by tailoring the power delivered to meet the actual load requirements. AC drives replace mechanical gearboxes, belts, hydraulic couplings, DC drives, servo-drives, or eddy current drives in many situations. AC drives provide an accurate and wide range...

A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter. Frequency (or hertz) is directly related to the motor’s speed (RPMs). In other words, the faster the f...

There are 5 important AC drive VFD limitations that should be considered when selecting the proper VFD for motor speed control applications. A VFD is an electronic circuit that controls the speed of an electric motor by adjusting both the voltage and the frequency applied to the motor. Prior to VFDs, motor speed was controlled through inefficient voltage regulators or mechanical means – ...

What is an electric drive? An electric drive is used to control the motion and speed of motors, robots and/or other electrical devices. Usually, a drive will have one or several electric motors. In the modern day, any control offered by these devices is often aided by software, which can help control accuracy. There are two main types of electric drives: AC drives and DC drives. What is an AC driv...

When it comes to AC drives vs DC drives, DC drives are commonly considered problematic, despite their prestige for having simple circuits, providing high start-up torque, and being ideal for applications with constant speed due to the requirement of commutators and brush assemblies in their motors. These motors can become worn over time, have operational issues, and will likely require labor to pr...
