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

Gear motors, like any mechanical system, can face certain challenges or issues that may affect their performance, reliability, or longevity. However, many of these challenges can be addressed through proper design, maintenance, and operational practices. Here are some common challenges associated with gear motors and potential solutions:
1. Gear Wear and Failure:
Over time, gears in a gear motor can experience wear, resulting in decreased performance or even failure. The following measures can address this challenge:
- Proper Lubrication: Regular lubrication with the appropriate lubricant can minimize friction and wear between gear teeth. It is essential to follow manufacturer recommendations for lubrication intervals and use high-quality lubricants suitable for the specific gear motor.
- Maintenance and Inspection: Routine maintenance and periodic inspections can help identify early signs of gear wear or damage. Timely replacement of worn gears or components can prevent further damage and ensure the gear motor’s optimal performance.
- Material Selection: Choosing gears made from durable and wear-resistant materials, such as hardened steel or specialized alloys, can increase their lifespan and resistance to wear.
2. Backlash and Inaccuracy:
Backlash, as discussed earlier, can introduce inaccuracies in gear motor systems. The following approaches can help address this issue:
- Anti-Backlash Gears: Using anti-backlash gears, which are designed to minimize or eliminate backlash, can significantly reduce inaccuracies caused by gear play.
- Tight Manufacturing Tolerances: Ensuring precise manufacturing tolerances during gear production helps minimize backlash and improve overall accuracy.
- Backlash Compensation: Implementing control algorithms or mechanisms to compensate for backlash can help mitigate its effects and improve the accuracy of the gear motor.
3. Noise and Vibrations:
Gear motors can generate noise and vibrations during operation, which may be undesirable in certain applications. The following strategies can help mitigate this challenge:
- Noise Dampening: Incorporating noise-dampening features, such as vibration-absorbing materials or isolation mounts, can reduce noise and vibrations transmitted from the gear motor to the surrounding environment.
- Quality Gears and Bearings: Using high-quality gears and bearings can minimize vibrations and noise generation. Precision-machined gears and well-maintained bearings help ensure smooth operation and reduce unwanted noise.
- Proper Alignment: Ensuring accurate alignment of gears, shafts, and other components reduces the likelihood of noise and vibrations caused by misalignment. Regular inspections and adjustments can help maintain optimal alignment.
4. Overheating and Thermal Management:
Heat buildup can be a challenge in gear motors, especially during prolonged or heavy-duty operation. Effective thermal management techniques can address this issue:

What is a gear motor, and how does it combine the functions of gears and a motor?
A gear motor is a type of motor that incorporates gears into its design to combine the functions of gears and a motor. It consists of a motor, which provides the mechanical power, and a set of gears, which transmit and modify this power to achieve specific output characteristics. Here’s a detailed explanation of what a gear motor is and how it combines the functions of gears and a motor:
A gear motor typically consists of two main components: the motor and the gear system. The motor is responsible for converting electrical energy into mechanical energy, generating rotational motion. The gear system, on the other hand, consists of multiple gears with different sizes and tooth configurations. These gears are meshed together in a specific arrangement to transmit and modify the output torque and speed of the motor.
The gears in a gear motor serve several functions:
1. Torque Amplification:
One of the primary functions of the gear system in a gear motor is to amplify the torque output of the motor. By using gears with different sizes, the input torque can be effectively multiplied or reduced. This allows the gear motor to provide higher torque at lower speeds or lower torque at higher speeds, depending on the gear arrangement. This torque amplification is beneficial in applications where high torque is required, such as in heavy machinery or vehicles.
2. Speed Reduction or Increase:
The gear system in a gear motor can also be used to reduce or increase the rotational speed of the motor output. By utilizing gears with different numbers of teeth, the gear ratio can be adjusted to achieve the desired speed output. For example, a gear motor with a higher gear ratio will output lower speed but higher torque, whereas a gear motor with a lower gear ratio will output higher speed but lower torque. This speed control capability allows for precise matching of motor output to the requirements of specific applications.
3. Directional Control:
Gears in a gear motor can be used to control the direction of rotation of the motor output shaft. By employing different combinations of gears, such as spur gears, bevel gears, or worm gears, the rotational direction can be changed. This directional control is crucial in applications where bidirectional movement is required, such as in conveyor systems or robotic arms.
4. Load Distribution:
The gear system in a gear motor helps distribute the load evenly across multiple gears, which reduces the stress on individual gears and increases the overall durability and lifespan of the motor. By sharing the load among multiple gears, the gear motor can handle higher torque applications without putting excessive strain on any particular gear. This load distribution capability is especially important in heavy-duty applications that require continuous operation under demanding conditions.
By combining the functions of gears and a motor, gear motors offer several advantages. They provide torque amplification, speed control, directional control, and load distribution capabilities, making them suitable for various applications that require precise and controlled mechanical power. Gear motors are commonly used in industries such as robotics, automotive, manufacturing, and automation, where reliable and efficient power transmission is essential.
