How To Control How A Motor Starts And Stops

If you're not familiar with the motor and drive industry, controlling a motor can be intimidating. Technology offers us many solutions when controlling motors and electronics, but not all of those solutions are equal. There are a number…

AC Electric Motors

AC electric motors operate by applying alternating current (AC) power to the electric motor. The main parts of  AC electric motors are the stator and rotor. The AC electric motors' stator consists of coils that are supplied with alternating…

VFD Manufacturers

When choosing VFD manufacturers for motor speed control equipment in production, it is recommended by Precision Electric to choose VFD manufacturers who offer extensive technical support for their products. Precision Electric recommends using…
Excellent Versus Horrible Packaging When Shipping A VFD

Shipping A VFD

Shipping a VFD (variable frequency drive) safely is important because electronic components can be easily damaged due to poor packaging. When shipping a VFD, the first step to safely package the VFD is to locate an appropriate size box…

Benefits of Using a Variable Speed Drive

Approximately one third of the world's electrical energy is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. This proves that significant energy efficiency improvement opportunities are available…

ABB Frequency Converters

ABB Frequency Converters are used to change the frequency and magnitude of the constant grid voltage to a variable load voltage. Frequency converters are especially used in variable frequency AC motor drives. Figure 1 shows the…

What is a Variable Speed Drive?

Variable speed drives are also known as variable frequency drives, VFD's, adjustable speed drives,  and inverters. Variable speed drives are solid state motor control systems used mainly for industrial manufacturing. Variable speed drives are…

Variable Frequency Drive Basics

Variable frequency drives are also known as (VFDs), variable speed drives (VSDs), adjustable speed drives, and inverters. Variable frequency drives are solid state controllers used in AC or DC electric motor applications. Most variable frequency…

Types of Variable Speed Drives

There are three general types of variable speed drives- DC Motor drives, Eddy Current Drives, and AC Motor drives. Each type of variable speed drive can be divided into different variations. Every variable speed drive system will include an…
