製品説明
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

What are the common signs of AC motor failure, and how can they be addressed?
AC motor failure can lead to disruptions in various industrial and commercial applications. Recognizing the common signs of motor failure is crucial for timely intervention and preventing further damage. Here are some typical signs of AC motor failure and potential ways to address them:
- Excessive Heat: Excessive heat is a common indicator of motor failure. If a motor feels excessively hot to the touch or emits a burning smell, it could signify issues such as overloaded windings, poor ventilation, or bearing problems. To address this, first, ensure that the motor is properly sized for the application. Check for obstructions around the motor that may be impeding airflow and causing overheating. Clean or replace dirty or clogged ventilation systems. If the issue persists, consult a qualified technician to inspect the motor windings and bearings and make any necessary repairs or replacements.
- Abnormal Noise or Vibration: Unusual noises or vibrations coming from an AC motor can indicate various problems. Excessive noise may be caused by loose or damaged components, misaligned shafts, or worn bearings. Excessive vibration can result from imbalanced rotors, misalignment, or worn-out motor parts. Addressing these issues involves inspecting and adjusting motor components, ensuring proper alignment, and replacing damaged or worn-out parts. Regular maintenance, including lubrication of bearings, can help prevent excessive noise and vibration and extend the motor’s lifespan.
- Intermittent Operation: Intermittent motor operation, where the motor starts and stops unexpectedly or fails to start consistently, can be a sign of motor failure. This can be caused by issues such as faulty wiring connections, damaged or worn motor brushes, or problems with the motor’s control circuitry. Check for loose or damaged wiring connections and make any necessary repairs. Inspect and replace worn or damaged motor brushes. If the motor still exhibits intermittent operation, it may require professional troubleshooting and repair by a qualified technician.
- Overheating or Tripping of Circuit Breakers: If an AC motor consistently causes circuit breakers to trip or if it repeatedly overheats, it indicates a problem that needs attention. Possible causes include high starting currents, excessive loads, or insulation breakdown. Verify that the motor is not overloaded and that the load is within the motor’s rated capacity. Check the motor’s insulation resistance to ensure it is within acceptable limits. If these measures do not resolve the issue, consult a professional to assess the motor and its electrical connections for any faults or insulation breakdown that may require repair or replacement.

AC モーターとは何ですか? DC モーターとどう違うのですか?
ACモーター（交流モーターとも呼ばれる）は、交流電流で動作する電気モーターの一種です。磁場の相互作用を通じて電気エネルギーを機械エネルギーに変換します。ACモーターは、家電製品から産業機械まで、様々な用途で広く使用されています。ACモーターとは何か、そしてDCモーターとの違いについて詳しく説明します。
ACモーター:
ACモーターは、ステータとローターという2つの主要部品で構成されています。ステータはモーターの固定部分であり、ステータ巻線が内蔵されています。これらの巻線は通常銅線で作られ、交流電流を流すと回転磁界を発生させるように特定の配置で配置されています。一方、ローターはモーターの回転部分であり、通常は導体バーまたはコイルを備えた積層鋼鉄コアで作られています。ローター巻線はシャフトに接続されており、ステータによって生成された回転磁界との相互作用によってローターが回転します。
ACモーターの動作は電磁誘導の原理に基づいています。ステータ巻線にAC電源が供給されると、変化する磁界がローター巻線に電圧を誘導し、さらに磁界が発生します。ステータの回転磁界とローターの磁界の相互作用によってトルクが発生し、ローターが回転します。回転速度はAC電源の周波数とモーターの極数に依存します。
DCモーター:
DCモーター（直流モーターとも呼ばれる）は、直流電流で動作します。トルクを生成するために磁場の相互作用を利用するACモーターとは異なり、DCモーターは整流の原理を利用して回転運動を生み出します。DCモーターは、ACモーターと同様に、ステータとローターで構成されています。ステータにはステータ巻線が巻かれており、ローターはコイルまたは永久磁石を備えた回転アーマチュアで構成されています。
DCモーターでは、ステーター巻線に直流電流を流すと磁界が発生します。ローターは、ブラシと整流子、または電子整流子のいずれかを用いて磁界に整流され、回転を開始します。ローター巻線を流れる電流の方向は連続的に反転し、回転が継続されます。DCモーターの速度は、モーターに印加する電圧を調整するか、電子速度制御方式を用いることで制御できます。
違い:
AC モーターと DC モーターの主な違いは次のとおりです。
- 電源: ACモーターは交流で動作します。交流は、ほとんどの住宅や商業ビルの標準的な電源です。一方、DCモーターは直流を必要とするため、通常は交流を直流に変換する電源が必要です。
- 工事： ACモーターとDCモーターは、ステーターとローターの構造は似ていますが、巻線の設計と配置が異なります。ACモーターは一般的に三相巻線を備えていますが、DCモーターは電機子巻線または永久磁石のいずれかを備えています。
- スピードコントロール: ACモーターは通常、電源周波数と極数によって決まる固定速度で動作します。一方、DCモーターは速度制御の柔軟性が高く、幅広い速度範囲で簡単に調整できます。
- 効率： ACモーターは一般的にDCモーターよりも効率が高いです。ACモーターはより高い電力密度を実現できるため、高出力アプリケーションに適している場合が多いです。一方、DCモーターは速度制御に優れており、精密な速度制御が求められるアプリケーションでよく使用されます。
- 用途: ACモーターは、産業機械、HVACシステム、ポンプ、コンプレッサーなどの用途で広く使用されています。DCモーターは、ロボット工学、電気自動車、コンピューターディスクドライブ、小型家電製品などに使用されています。
結論として、ACモーターとDCモーターは、電源、構造、速度制御、効率、そして用途において異なります。ACモーターは磁場の相互作用を利用して交流で動作しますが、DCモーターは整流を利用して直流で動作します。それぞれのモーターには利点があり、電力要件、速度制御の必要性、効率性などの要素に基づいて、異なる用途に適しています。
