Application:

• There are wide usages of gear motors, mainly in governance, mining, construction, blowing motors, elevating machinery…and etc. Let’s make it in easy way to understand. Whenever you need to adjust the speed, you will need gear motors. Nowadays, treadmills, cranes, golf carts….and etc. all are gear reducer’s applications.

Features:

• What’s the feature of gear motors?
• When we talk about gear motors, we usually mean the Gear Reducer Motors. They contain two parts, induction motor and gear box. The main function of gear reducer motor are two points. First, reducing the speed meanwhile increasing the output torque power. Secondly, changing the direction of input power. Gear boxes are used for changing speed, for example, if we use two gears (one big gear & one small gear) to transfer power to another rotating shaft, the gear box is applied to change the speed. Equipped with electromagnetic brake and you can control complex counter-clockwise or clockwise rotation. There are various of speed reduction ratio for options.

Basic models:

• According to functions, allowable torque, transmissions and applications, there are six models as listed below: Helical gear reducer, Bevel gear reducer, Worm wheel reducer, Planetary gear speed reducer, Oblique gear speed reducer and Harmonic gear reducer. Furthermore, we can roughly divide them into 3 types by axes, which are Parallel axes, Intersecting axes and non-parallel & none intersecting axes. At present, the most common types are Helical gear reducers, which are widely used in AC motors.

Advantages:

• Firstly, lower RPM. When machines need low speed, we can use speed reducers to lower the motor RPM. Besides, reducers can solve the un-efficiency problem during rotating in low RPM, and make the motor stable. Secondly, increase torque. There are many ways to increase torque. Some will suggest increase the watt (HP) of motors. However, this will increase the cost of current device and driver. Therefore, the cost of controlling system increase. Besides, the volume of motor become bigger for bigger HP. So we can say the best way to increase torque is to equip with reducer—lower RPM and high Torque. Thirdly, with equipping the reducer, the RPM becomes small, then we are able to position the angle precisely. Finally, increase loading.

Tolerance:

• We can control the tolerance to make stator smooth and accurate. Please understand the tolerance differs from different material of silicon steel lamination and design of mold. Usually, it is within 0.03mm-0.05mm. Our material is directly from China Steel. As one of the leading silicon steel lamination manufacturer in the world, the quality of laminations is guaranteed, China Steel is also the supplier for Telsa Automotive in Taiwan. Certainly, there are different grades of laminations for choosing by various design.

IE3 / IE4 Efficiency:

• We are proud to claim that motors using our stator rotor passed the IE3/IE4 testing in UL laboratory. Our material is directly supplied from the top supplier, China Steel. With correct design and our rich experience on mold developing, we can guarantee the quality. We also have a subsidiary company for motor in Taiwan. We have the ability to develop new motor, and do the OEM/ODM business. As to the details, please contact us for further discussion. It would save time, if you could provide us with the drawing of stator rotor in advance. If you also need die aluminum casting, please also provide the drawing of your aluminum injection way.
