General Purpose 3-phase Induction Motors

INTRODUCTION

New efficiency classes for the low-voltage three-phase motors (IE = International Efficiency).

Along with the international discussion on energy efficiency a worldwide harmonized energy efficiency classification
system has been established for low-voltage three-phase asynchronous motors.
For many years low-voltage three-phase motors in the European Union have been sold in three efficiency classes EFF3,
EFF2 and EFF1. Aside from this, many different efficiency classification systems have been introduced and well-proven in
many countries all over the world.

This was the reason for the International Electrotechnical Commission IEC to develop and publish an energy efficiency
standard which replaces all previous national issues. In parallel IEC developed and issued a new standard for determining
motor efficiency. The new standard IEC 60034-30 defines and harmonizes worldwide the efficiency classes IE1, IE2 and IE3
for low-voltage three-phase motors in the power range from 0.75 kW to 375 kW (2p=2, 4, 6):

IE1 = Standard Efficiency

IE2 = High Efficiency
IE3 = Premium Efficiency

From now motors can be offered and sold with the new classes IE1, IE2 and IE3.
In that case the efficiency has to be determined according to the new requirements given in the IEC 60034-2-1 standard.

According to the Comission Regulation (EC) No 640/2009 (introduced in July 2009) the required efficiency class
of general-purpose motors (introduced to the market in future) will be as follows:

From 16 June 2011, motors placed for the first-time on the market shall have a minimum efficiency class of IE2.

From 1 January 2015: motors with a rated output between 7.5 - 375 kW shall have a minimum efficiency class of IE3,
or IE2 if they are operated/equipped with electronic speed control (VSD).

From 1 January 2017: motors with a rated output between 0.75 - 375 kW shall have a minimum efficiency class of IE3,
or IE2 if they are operated/equipped with electronic speed control (VSD).

Electronic speed control is carried out using a frequency converter (VSD) that adjusts the
speed of the motor - and therefore the torque produced - based on the energy needed.

IE2 (0,75 - 375kW) Change in the law from 16.06.2011.

EFFICIENCY OF MOTORS
Cantoni Motor has in offer general purpose standard efficiency motors of (2) Sg, Sh series which fulfil IE1
class requirements according to the IEC 60034-30 standard.

The present catalogue describes the electric motors which belong to the efficiency class IE2 (High Efficiency)
and motors excluded from the IEC 60034-30 standard (motors with 2p = 8, 10, 12 and with rated output below
0.75kW and above 375kW).

Comparison between the efficiency of Cantoni Group motors (for example 2p=4)
and efficiency class IE1/IE2 requirements according to the IEC 60034-30.

The efficiency class system specified under IEC 60034-30 is valid for low voltage three phase
squirrel cage induction motors with the following specifications:

· Rated voltage up to 1.000 V

· Rated output between 0.75 kW and 375 kW
· Either 2, 4 or 6 poles
· Rated on the basis of continuous duty (S1) or intermittent periodic duty (S3) with
cyclic duration factor of 80% or higher
· Capable of operating direct on-line
· Rated for operating conditions in accordance with IEC 60034-1 (temperature,
installation altitude, etc.)

Motors with flanges, feet and/or shafts with mechanical dimensions different from IEC 60072-1
are also covered by this standard.

Value of radial force FR acting on the shaft end for a Value of force FR acting on any point of the shaft end
given belt pulley diameter is calculated according to (between points X=max and X=0) may be calculated
the following formula: according to the following formula:

where: P - motor output [kW] where: FX0 - value of FR force acting on the beginning of the shaft end
DK - belt pulley diameter [m] FXMAX - value of FR force acting on the end of the shaft end
n - speed [rpm] E - lenght of the shaft end
k - belt tension factor:
for V-belts k=2,2
for flat belts k=3

ORDERING INFORMATION
Orders for motors should specify: When ordering high-power or special purpose motors one
should also indicate:

motor type designation, required direction of rotation,

rated output, required degree of interior protection,
rated speed, method of start-up,
operating duty, method of coupling with the driven unit (gears,
dimensions of belt pulleys, etc.),
supply voltage and connection,
type of machine driven (nature of load), including the
frequency,
moment of inertia J or flywheel effect GD2 brought to the
mounting arrangements, end shield material, motor shaft,
degree of protection, other customer’s specifications.
type of machine driven,
other details of regarding special requests, When ordering spare parts one should specify:

and information concerning additional accessories e.g. full designation of the motor type including its serial
number (provided on the nameplate) or catalogue number,
degree of protection,
thermal protection,
mounting arrangement,
anticondensation heaters,
name of part,
vibration sensors,
number of pieces.
etc.

As part of our development program, we reserve the right

to alter or amend any of the specifications without giving prior notice
