International electric motor efficiency standards IEC created a standard for indicating the efficiency classes of electric motors. Some countries use other efficiency standards. In many cases, the IEC efficiency levels overlap with these standards.
What are IE standards?
Internationally, there is a standard which stipulates the energy efficiency of low voltage AC motors, namely the International Efficiency (IE). The purpose of which is to promote higher energy efficiency to reduce the energy consumption and the energy cost of low voltage AC motors.
What IEC 3?
IEC 62196-3 extends IEC 62196-1 and describes specific designs of vehicle connectors and vehicle inlets that are intended to be used for DC charging of electric vehicles in mode 4 as described by IEC 61851-1 and IEC 61851-23. The specific designs are grouped into several configurations.
What is NEMA IEC?
In measuring electric motors and motor controls, there are two standards in use: the National Electrical Manufacturers Association (NEMA) and the International Electrotechnical Commission (IEC). NEMA is mostly used in North America while IEC is used in most parts of the world.
What is iec34?
IEC 60034-30 specifies energy-efficiency classes for single-speed, continuous duty(S1), three-phase, cage-induction motors with 2, 4 or 6 poles. It classifies three classes: IE1 (standard), IE2 (high) and IE3 (premium). For each class the efficiency is defined for a rated output range from 0.75 to 375 kW.
What is IEC standard for motor?
The IEC is the standard for electric motors for the rest of the world. Similar to NEMA, IEC publishes Standard 60034-1:2010, the standard outside North America. NEMA and IEC motors are similar in size, efficiency and output power.
What is IEC 34 1?
IEC-34-1 | Rotating electrical machines - Part 1: Rating and performanc | Document Center, Inc.
What is meant by Standard motor efficiency?
Motor efficiency is the ratio of mechanical power output to electrical power input. In other words, motor efficiency represents the percent of input energy that is converted into useful work. A motor's nameplate rating is based on output horsepower. (hp), which is fixed for continuous operation at full load.
What is a standard DC motor?
A simple DC motor has a stationary set of magnets in the stator and an armature with one or more windings of insulated wire wrapped around a soft iron core that concentrates the magnetic field. The windings usually have multiple turns around the core, and in large motors there can be several parallel current paths.
What is DC motor used for?
The term 'DC motor' is used to refer to any rotary electrical machine that converts direct current electrical energy into mechanical energy. DC motors can vary in size and power from small motors in toys and appliances to large mechanisms that power vehicles, pull elevators and hoists, and drive steel rolling mills.
What are the 3 types of DC motors?
There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
