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

Can brake motors be used in conjunction with other motion control methods?
Yes, brake motors can be used in conjunction with other motion control methods to achieve precise and efficient control over mechanical systems. Brake motors provide braking functionality, while other motion control methods offer various means of controlling the speed, position, and acceleration of the system. Combining brake motors with other motion control methods allows for enhanced overall system performance and versatility. Here’s a detailed explanation of how brake motors can be used in conjunction with other motion control methods:
- Variable Frequency Drives (VFDs): Brake motors can be used in conjunction with VFDs, which are electronic devices that control the speed and torque of an electric motor. VFDs enable precise speed control, acceleration, and deceleration of the motor by adjusting the frequency and voltage supplied to the motor. By incorporating a brake motor with a VFD, the system benefits from both the braking capability of the motor and the advanced speed control provided by the VFD.
- Servo Systems: Servo systems are motion control systems that utilize servo motors and feedback mechanisms to achieve highly accurate control over position, velocity, and torque. In certain applications where rapid and precise positioning is required, brake motors can be used in conjunction with servo systems. The brake motor provides the braking function when the system needs to hold position or decelerate rapidly, while the servo system controls the dynamic motion and positioning tasks.
- Stepper Motor Control: Stepper motors are widely used in applications that require precise control over position and speed. Brake motors can be utilized alongside stepper motor control systems to provide braking functionality when the motor needs to hold position or prevent undesired movement. This combination allows for improved stability and control over the stepper motor system, especially in applications where holding torque and quick deceleration are important.
- Hydraulic or Pneumatic Systems: In some industrial applications, hydraulic or pneumatic systems are used for motion control. Brake motors can be integrated into these systems to provide additional braking capability when needed. For example, a brake motor can be employed to hold a specific position or provide emergency braking in a hydraulic or pneumatic actuator system, enhancing safety and control.

How do brake motors handle variations in load and stopping requirements?
Brake motors are designed to handle variations in load and stopping requirements by incorporating specific features and mechanisms that allow for flexibility and adaptability. These features enable brake motors to effectively respond to changes in load conditions and meet the diverse stopping requirements of different applications. Here’s a detailed explanation of how brake motors handle variations in load and stopping requirements:
1. Adjustable Braking Torque: Brake motors often have adjustable braking torque, allowing operators to modify the stopping force according to the specific load requirements. By adjusting the braking torque, brake motors can accommodate variations in load size, weight, and inertia. Higher braking torque can be set for heavier loads, while lower braking torque can be selected for lighter loads, ensuring optimal stopping performance and preventing excessive wear or damage to the braking system.
2. Controlled Response Time: Brake motors provide controlled response times, allowing for precise and efficient stopping according to the application requirements. The response time refers to the duration between the command to stop and the actual cessation of rotation. Brake motors can be designed with adjustable response times, enabling operators to set the desired stopping speed based on the load characteristics and safety considerations. This flexibility ensures that the braking action is appropriately matched to the load and stopping requirements.
3. Dynamic Braking: Dynamic braking is a feature found in some brake motors that helps handle variations in load and stopping requirements. When the motor is de-energized, dynamic braking converts the kinetic energy of the rotating load into electrical energy, which is dissipated as heat through a resistor or regenerative braking system. This braking mechanism allows brake motors to handle different load conditions and varying stopping requirements, dissipating excess energy and bringing the rotating equipment to a controlled stop.
4. Integrated Control Systems: Brake motors often come equipped with integrated control systems that allow for customized programming and adjustment of the braking parameters. These control systems enable operators to adapt the braking performance based on the load characteristics and stopping requirements. By adjusting parameters such as braking torque, response time, and braking profiles, brake motors can handle variations in load and achieve the desired stopping performance for different applications.
5. Monitoring and Feedback: Some brake motor systems incorporate monitoring and feedback mechanisms to provide real-time information about the load conditions and stopping performance. This feedback can include data on motor temperature, current consumption, or position feedback from encoders or sensors. By continuously monitoring these parameters, brake motors can dynamically adjust their braking action to accommodate variations in load and ensure optimal stopping performance.
6. Adaptable Brake Design: Brake motors are designed with consideration for load variations and stopping requirements. The brake design takes into account factors such as braking surface area, material composition, and cooling methods. These design features allow brake motors to handle different load conditions effectively and provide consistent and reliable stopping performance under varying circumstances.
By incorporating adjustable braking torque, controlled response time, dynamic braking, integrated control systems, monitoring and feedback mechanisms, and adaptable brake designs, brake motors can handle variations in load and stopping requirements. These features enhance the versatility and performance of brake motors, making them suitable for a wide range of applications across different industries.
