Product Description

We,GOGOGO Mechanical&Electrical Co.,Ltd specialize in high quality energy-efficient electric motors. The combination of the best available materials, high quality sheet metal and the right amount of copper in the rotor/stator makes GOGOGO’s electric motors highly energy-efficient.

We design our electric motors to fit and match our customer’s requirements at our production site. The electric motors can be supplemented with a range of options and accessories or modified with a special design to endure any environment.
 

Electric motors account for a large part of the electricity used. If we look at the world, electric motors account for about 65 percent of the electricity used in industry. To reduce this use of electricity, there are legal requirements regarding the efficiency of electric motors manufactured in the EU, or exported into the EU.

Three-phase, single-speed asynchronous motors are covered by the requirements today. Asynchronous motors are the most common type of motor and account for 90 percent of the electricity consumption of all electric motors in the power range 0.75 – 375 kW.

According to that standard, the energy efficiency classes have the designations IE1, IE2, IE3 and IE4, where IE4 has the highest efficiency.

 

Revision of the standard

A revision of the standard was decided by the Ecodesign Committee in 2019. The revision was published on October 1, 2019. The following will apply:

For electric motors

From July 1, 2571

2-, 4-, 6- and 8-pole motors from 0.75 – 1000 kW (previously up to 375kW) are included in efficiency class IE3.

Motors within the range 0.12 – 0.75 kW must meet efficiency class IE2.

The previous possibility to replace IE3 motors with an IE2 motor with frequency drive disappears.

From July 1, 2571

For 2-, 4-, 6- and 8-pole motors from 0.12 – 1000 kW, the efficiency class IE2 now also applies to Ex eb certified motors with high safety.

Single phase motors with greater power than 0.12 kW are covered by the corresponding IE2 class.

The higher efficiency class IE4 applies to 2, 4 and 6-pole motors between 75 – 200 kW.

For frequency inverters

From July 1, 2571

For use with electric motors with power from 0.12 – 1000 kW, the frequency inverter must pass efficiency class IE2 specially designed for inverters.

Current requirements according to the Directive

Since 16 June, 2011 it is prohibited to place electric motors below energy efficiency class IE2 on the market, or to put them into service in the EU.

Since January 1, 2015, electric motors within the range 7.5 – 375 kW (2-, 4-, and 6-pole) must meet the requirements for IE3, or IE2 if the latter is combined with frequency inverters for speed control. The legal requirement thus provides 2 options.

From January 1, 2017, the requirements were tightened so that all motors 0.75 – 375 kW (2-, 4-, and 6-pole) must meet the requirements for IE3, or IE2 if they are combined with frequency inverters.

Exemptions from the current directive

  • Operation other than S1 (continuous drive) or S3 (intermittent drive) with a nominal cyclicity factor of 80 percent or lower.
  • Made for assembly with frequency inverters (integral motors).
  • Electric motors made for use in liquid.
  • Electric motors that are fully integrated into a product (e.g. a gear, pump, fan or compressor) where the energy performance is not tested independently of the product.
  • Brake motors

Electric motors intended for operation exclusively:

  • At altitudes exceeding 4 000 CHINAMFG above sea level.
  • If ambient air temperatures exceed 60°C.
  • Where maximum operating temperature exceeds 400°C.
  • Where ambient air temperatures are less than -30°C for all motors, or less than 0°C for motors with water cooling.
  • In explosive atmospheres (as defined in Directive 94/9 / EC 9)

The requirements do not apply to ships or other means of transport that carry goods or persons, since there must be specially designed engines for this purpose. (If the same mobile conveyor belt is used on ships as well as on land, the rules apply).

Also, the requirements do not apply to repair of motors previously placed on the market, or put into service – unless the repair is so extensive that the product will in practice be brand new.

If the motor is to be further exported for use outside Europe, the requirements do not apply.

Some other requirements apply to water-cooled motors

3 phase motor

How do 3-phase motors differ from single-phase motors?

3-phase motors and single-phase motors differ in several aspects, including their power supply, construction, performance characteristics, and applications. Here’s a detailed explanation of the differences between 3-phase motors and single-phase motors:

  • Power Supply: The primary difference between 3-phase motors and single-phase motors is their power supply. 3-phase motors require a three-phase power supply, which consists of three alternating current (AC) voltage waveforms that are 120 degrees out of phase with each other. In contrast, single-phase motors operate on a single-phase power supply, which consists of a single AC voltage waveform.
  • Construction: The construction of 3-phase motors and single-phase motors also differs. 3-phase motors have three sets of windings evenly spaced around the motor’s stator, whereas single-phase motors typically have only one set of windings. The multiple windings in 3-phase motors enable the creation of a rotating magnetic field, which is essential for their operation.
  • Starting Mechanism: 3-phase motors and single-phase motors have different starting mechanisms. 3-phase motors can start on their own with a simple direct-on-line (DOL) starting method, where the motor is connected directly to the power supply. In contrast, single-phase motors require additional starting mechanisms, such as capacitors or centrifugal switches, to overcome the need for a rotating magnetic field during startup.
  • Starting Torque: 3-phase motors tend to have higher starting torque compared to single-phase motors. The balanced three-phase power supply and the design of 3-phase motors allow them to produce a strong rotating magnetic field, enabling efficient starting and acceleration. Single-phase motors, on the other hand, often experience lower starting torque due to the absence of a rotating magnetic field during startup.
  • Efficiency: In terms of efficiency, 3-phase motors are generally more efficient than single-phase motors. The balanced three-phase power supply and the design of 3-phase motors result in smoother operation and reduced losses compared to single-phase motors. This higher efficiency translates to better performance and energy savings in applications where 3-phase motors are utilized.
  • Power Rating: 3-phase motors are commonly available in higher power ratings compared to single-phase motors. The ability of 3-phase motors to deliver higher power output makes them suitable for applications that require greater torque and horsepower, such as heavy-duty industrial machinery and equipment. Single-phase motors are typically used in lower power applications, such as household appliances and small tools.
  • Applications: The applications of 3-phase motors and single-phase motors also differ. 3-phase motors are widely used in industrial and commercial applications, including pumps, compressors, HVAC systems, electric vehicles, and robotics. Single-phase motors are commonly found in residential and small-scale applications, such as household appliances (e.g., refrigerators, air conditioners, and washing machines) and small tools (e.g., fans and power tools).

These are the key differences between 3-phase motors and single-phase motors. While 3-phase motors offer advantages in terms of efficiency, starting torque, and power rating, single-phase motors are suitable for smaller-scale applications and residential use. The selection of the motor type depends on the specific requirements of the application and the availability of the appropriate power supply.
