In daily life and industrial production, the motor as a kind of electrical energy into mechanical energy conversion equipment, plays a pivotal role. Whether it is a household appliance in the small motor, or a large factory motor, they have a piece of information called “nameplate” identification plate. The motor nameplate is the motor “ID card”, which records key information about the motor. Learn to read the motor nameplate, not only can quickly understand the basic parameters of the motor, but also help the correct use and maintenance of the motor. Next, with three minutes to take you easily mastered!

A. Nameplate Location

First, find the nameplate on the motor. The nameplate is usually secured in a prominent location on the motor, such as on the side or top of the housing, or sometimes mounted near the junction box. It is a metal or plastic plate with clear, durable text and numerical information printed on it.

B. Basic Information

○1 Brand name--FuXing Motor: the brand name of the motor, for example, the motor on the picture is from fuxing motor.

○2 Motor model--YE3-180L-4: the name of the motor type, for example, the motor on the picture is a YE3 series frame number 180L (the “180” in the seat number 180L is the center height of the seat in mm) with a rotational speed of 4000 RPM (the “L” is the number of poles of the seat). For example, the motor shown in the figure is a YE3 series motor with the frame number 180L (“180” in the frame number 180L is the height of the center of the frame (mm), and “L” refers to the designation of the number of poles of the frame), and the rotational speed is 4,000 rpm.

○3 IM--B3: Installation, e.g., the motor shown in the figure is installed horizontally as B3.

○4 Motor name--High efficiency-3-Phase Induction Motor: It is the name of the motor product, for example, the name of the motor in the picture is “High efficiency-3-Phase Induction Motor”. For example, the name of the motor in the picture is “High efficiency-3-Phase Induction Motor”, we can know that it is a three-phase asynchronous motor.

○5 Serial number--NO.A1102652: It is the serial number of the motor in the manufacturer, which is the proof whether the motor is under warranty or not.

○6 Three phase motor--3.Mot: It means the motor is a three phase asynchronous motor.

○7 Insulation class--F: Insulation class. For example, the insulation class of the motor shown is F. The maximum operating temperature is 155, and mica, fiberglass, and synthetic resin are used as the main insulating materials. Ordinary motors are generally class F. (Want to know more about the motor insulation class please motor link)

○8 Class of protection--IP 55: It refers to the protection class of the motor. For example, the protection class of the motor on the picture is IP55, which means that it can prevent the entry of foreign objects and dust, completely prevent the intrusion of foreign objects, although it can not completely prevent the intrusion of dust, but the amount of dust intrusion will not affect the normal operation of the electrical appliances; it can prevent the infiltration of sprinkler water and prevent the low-pressure sprinkler water that lasts at least 3 minutes.

○9 Voltage - Voltage 380 660: is the voltage of the motor in different wiring methods. For example, the motor on the diagram has a voltage of 380V under the △ connection method, while the voltage under the Y connection method is 660V.

○10 Connection method--△, Y: The connection method of the motor is divided into two types: △ and Y. (For more information about motor connection method, please refer to the following table. (For more information on motor wiring methods, please click on the link)

○11 Frequency--Hz 50 50: It is the frequency of the motor. For example, the motor frequency on the diagram is 50Hz.

○12 Output power--Kw: It is the output power of the motor. For example, the output power of the motor on the diagram is 22Kw.

○13 Drive-end bearing and Non drive end--Drive-end bearing 63112RZ-C3;Non drive end63112RZ-C3: is the material of the drive-end bearing and non drive-end bearing of the motor. For example, the type of both drive-end bearing and non-drive-end bearing of the motor shown in the figure is 63112RZ-C3.

○14 Name of manufacturer--Shandong fuxing motor company: The name of the motor manufacturer. For example, the name of the manufacturer of the motor shown in the figure is Shandong fuxing motor company.

○15 Production date--Date202309: The production date of the motor. For example, the production date of the motor on the diagram is September 2023.

○16 Electric current--A 43.4 25.0: It is the current of the motor. For example, the current of the motor shown in the diagram is 43.4 in the △ connection and 25.0 in the Y connection.

○17 Number of rotations--rmp 1470 1470 : This refers to the rotational speed of the motor. For example, the motor shown in the figure has a rpm of 1470 for both the △ and Y connection methods.

○18 ○19 Schematic diagram of △ connection method and Y connection method. (For more information about motor wiring method, please click the link )

○20 Efficiency--EFF 95.4%: It is the energy efficiency of the motor. For example, the energy efficiency of the motor on the diagram is 95.4%, which is classified as IE3 according to IEC, and class 2 according to Chinese energy efficiency rating. (To learn more about the energy efficiency of motors please click on the link)

○21 Weight---170Kg: It is the weight of the motor. For example, the weight of the motor on the chart is 170Kg.

○22 Power factor-- cosφ0.87: It is the power factor of the motor. For example, the power factor of the motor on the diagram is 0.87.

○23 Meet the standard--ISO9001 IEC60034-1: It means the standard that the motor meets. For example, the motor on the diagram meets the Chinese standard ISO9001 and the international standard IEC60034-1.

C. Caution

- READ CAREFULLY: Always read all the information on the nameplate before use to ensure that the motor meets the conditions of use.

- Save the information: Record or take photos of the motor nameplate information to save it for future use.

- Match the demand: When purchasing motors, choose the right power, voltage, speed and other parameters according to the actual demand to avoid waste of resources and safety hazards.

Through this three-minute study, I believe you have mastered how to quickly and effectively read the motor nameplate. Motor nameplate is small but informative, correctly understand and utilize this information will help you better use and maintain the motor, improve efficiency and ensure production safety.
