Motor Enclosure Type

The motor standards are grouped in two major categories: NEMA and IEC.

How a Three-Phase Motor Works

How a Three-Phase Motor WorksBy Isaiah David;Three-phase motors are motors designed to run on the three-phase alternating current (AC) power used in many industrial applications. AC electricity changes direction from negative to positive and back many tim

How to Read Motor Nameplate Data

Electric motors are normally equipped with a nameplate and if you dont have the manufacturers documentation the best way to get information about the motors features and specifications is to read it out from the nameplate.

The Six Kinds of Energy-Saving Plan for Motors

Motor energy dissipation performance is mainly in the following aspects:1.The motor load rate is low. Due to the improper selection of motor, the rich amount of or changes in production technology, will make the motor actual work load far less than rated

How to Determine an AC Induction Motor Speed

Rated speed of the motor selection, according to the requirements of the production machinery and the driving device to consider the ratio of the transmission device.

How to choose a general purpose motor vs an inverter-duty motor?

General purpose motors have been around for many years. They are the workhorse of almost every industry.An inverter-duty motor is a much newer concept that became necessary as motors began to be driven by VFDs (inverters or AC drives). An inverter duty mo

How to choose the rated voltage of the motor in practical application?

Rated voltage is a very important parameter of motors. Motors with the same power can have different voltage levels; Such as 220V, 380V, 400V, 420V, 440V, 660V and 690V in low-voltage motors, and 3000V, 6000V and 10000V in high-voltage motors. When select

Why can one motor run at two rated voltages?

In many motor applications, motors are required to operate in dual voltage mode, i.e. the same motor can operate normally at different rated voltages, such as 380/660V, 6 /10kV.The direct factor that determines the rated voltage of the motor is the insula

Aluminum Motor VS Cast Iron Motor

Which should be chosen between aluminum motor and cast iron motor?

Performance Requirements for Motors Operating in Plateau Environment

What are the special performance requirements for motors operating in Plateau Environment?

Analysis of Motor Shaft Broken

1.Assemble mistakes . When the motor is not concentric with the driving equipment, the motor bears excessive loads, which eventually leads to metal fatigue. When the radial load on the extension end of the motor shaft is too large, it will cause the bend

NEMA standard motor VS IEC standard motor

The motor standards are grouped in two major categories: NEMA and IEC.
