The construction of motor includes stator, rotor, copper winding, shaft and aluminum/iron cover. Between stator and rotor, there is a small gas gap. Therefore, the rotor won’t touch the stator while rotating. Using the feature of like charges repel each other while opposite charges attract to drive the armature. With the rapid usage of three-phase motors, induction asynchronous motors are invented. Due to the construction is simple, the cost is cheaper. Besides, induction motors are easily to do the maintenance. Furthermore, it is also easy to adjust the ratio of RPM and torque. Induction motors are the most common type of motor, nearly 90% among all motors!! There are thousands of applications of induction motors to combined with other mechanical devices, such as brake, ATC, gearbox and so on.

Application:

• There are wide range of industrial motors, such as brake motors which is designed to require fast stops for safety reason and precise positioning. Or applied on centrifugal pump motors which designed for machinery usage. Choosing suitable stator & rotor is according to different applications. First of all, you choose stator and rotor based on the outer diameter and output power. Remember it is also changed and adjusted depending on your system and mechanic structure. Besides, there are still lots of factors to be considered, including power supply, actuation method, torque power (determined by load), installing space, environment conditions and cost. Certainly, we also refer to the IEC frame no. to help you figure out the suitable stator and rotor.

Phase:

• According to different phases, we can divide induction motors into two types, single-phase or three-phase. Due to single phase motor induction motor is not able to form a rotary magnetic field automatically, we must equip with other start device, for example a capacitor, to help the motor start. The advantages of single phase motors are easy to get current, less cost, low noise and low maintenance. As to the three phase motors, there are different phases to make stator create the rotary magnetic field. There are two types - Squirrel cage type and Winding type. The advantages are simple construction, long lifespan, easy maintenance and start easily. However, it is hard to adjust the RPM. While the RPM increases, the torque decreases. Finally, the start torque is relatively smaller. It’s important for us to know your demand voltage and the working duty, S1 to S6. Then, we are able to recommend you the suitable stator and rotor for your motors.

Meet UL regulations:

• Tayguei is a professional manufacturer of stator rotor lamination (punching / stamping sheet) nearly 40 years. Our subsidiary company which manufacture a wide range of AC/DC motors. We have the first UL laboratory of USA association in Taiwan. We are proud to say motors made of our silicon steel laminations pass the strict testing and reach the high efficiency IE3. Those motors are three phases, 2 poles or 4 poles. The Hose Power can reach 10HP. If you need the testing result for reference, please feel free to contact us.

Tolerance:

• We can control the tolerance to make stator cutting edge 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 stepping mold can also reach to such strict tolerance. All steel lamination coils are directly from China Steel Cooperation (CSC), China Steel is also the supplier for Telsa Automotive in Taiwan. As one of the leading silicon steel lamination manufacturer in the world, the quality of laminations is guaranteed. For example, the iron loss of 50CS1300 is only 5.88 W15/50. Certainly, there are different grades of laminations for choosing by various design. For industrial motors, we usually use 50CS800 for IE4 motors and 50CS1300 for IE3 motors. The thickness of silicon lamination is 0.5mm.

IE3 / IE4 Efficiency:

• 90% of motor efficiency is determined by stator & rotor. High efficiency motors offers a reduction on electricity power consuming and high efficiency on motors. 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 Cooperation (CSC). 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 support customers develop new motors, 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.
