Features:SEW geared motors are designed on the basis of a modular system with a wide range of motor combinations, mounting positions and structural solutions. The format is: the first part uses the uppercase pinyin letters to indicate the product code, the second part uses Arabic numerals to indicate the design number, and the third part uses Arabic numerals to indicate the machine number. Speed: The rated speed, rated frequency, rated load of the motor, the motor's speed per minute (r/min); the synchronous speed of the 2-pole motor is 3000r/min. SEW is responsible for promoting its products, and must sign its logo. 2. Just enter the serial number on the nameplate of the sew. CT stands for Constant Torque and VT stands for Variable Torque. When the motor is rated for voltage and the rated power is output on its shaft, the value of the line current drawn by the stator from the power source is called the rated current. Source: www.manualsdir.com. It should not be used as a method of increasing motor horsepower. Work quota: refers to the duration of motor operation. Using an under powered motor or drive could damage equipment and lead to unnecessary downtime and expense. Deceleration also reduces the inertia of the load, and the reduction of inertia is the square of the reduction ratio. endobj Another important measured variable for a gearmotor is the maximum torque on the output side. 1. The machine is directly matched and the other end is coupled to the fixed bracket. The machine is directly matched and the other end is coupled to the fixed bracket.2. Excitation current: refers to the excitation current (A) of the synchronous motor during rated operation. Identify the information of the manufacturing year. Check the cause, remove the fault, and replace the oil before continuing operation. Standard gearmotors feature an impressive variety of types, the ideal graduation over a multitude of sizes, and the widest range of designs. $399.99 + $32.83 shipping. The reducer is a mechanical transmission device in many fields of the national economy. Oils with the same grade and different viscosity are allowed to be mixed. Consult your manufacturer for more information about bearings. voltage to which one phase (winding) of the installed motor can be subjected (here 254-277 V), Higher value: Max. This can make reading a motor nameplate a difficult or frustrating task. The speed ratio i between the input speed and output speed of the gear unit serves as a measure of this. ~&q:M8u*/wh[7}&|~_?$3

Generally, two voltages are specified for a gearmotor, for example 230 V / 400 V. The lower voltage, 230 V, specifies that one phase of the installed motor (one motor winding) has a maximum load of 230 V. 400 V is the maximum voltage that the motors outer conductor can handle. According to the gear shape, they can be divided into cylindrical gears.
When the stator and rotor are thermally graded differently, they should be indicated separately (separated by diagonal lines).
Frequency is directly related to the motors speed. Due to improper installation of this type of coupling, unnecessary external loads may be caused, resulting in early damage of the bearing and even breakage of the output shaft in severe cases. endstream

However, depending on the amount of rotor slip the motor was designed for you may see the RPM listed as 1775 or 1750, et cetera. TEFC A Totally Enclosed Fan Cooled enclosure prevents air from flowing freely into the motor. The metal is zinc alloy, copper, iron, aluminum, stainless steel, etc., but it is mainly produced with aluminum, because the processed nameplate is relatively high-grade and durable. Most manufacturers display information differently, and nameplates often get dirty, damaged, and occasionally are removed. Under some circumstances using a VFD to reduce speed by 20% can result in energy savings of 50%. Need help with SO (serial number) lookup on SEW-EURODRIVE product nameplates? This number is extremely important, especially when dealing with electrical components. Below is a sample nameplate. Installation of the anti-torque bracket The anti-torque bracket should be installed on the side of the working machine facing the reducer to reduce the bending moment attached to the working machine shaft. According to the specified installation device, the staff can conveniently approach the oil mark, vent plug and drain plug. 1. There are many types of reducers.

The reducer is a mechanical transmission device in many fields of the national economy. Oils with the same grade and different viscosity are allowed to be mixed. Consult your manufacturer for more information about bearings. voltage to which one phase (winding) of the installed motor can be subjected (here 254-277 V), Higher value: Max. This can make reading a motor nameplate a difficult or frustrating task. The speed ratio i between the input speed and output speed of the gear unit serves as a measure of this. ~&q:M8u*/wh[7}&|~_?$3
#N'c~"Yc/U\ r 4xt?;~Mx'i Indicates how energy efficient the gearmotor is. 
Motors that do not fit this specification can be rewound to meet these requirements. 
NEMA frame size outlines motor footprint and shaft dimensions. Essentially, operation on a 400 V grid requires a star connection, whereas a delta connection should be used for the lower voltage (230 V). It is often used as a reduction gear between the prime mover and the work machine.

When operating at 50 Hz, this gearmotor has an efficiency of 84% and is in line with IE2. -?gwf@$I:i?S.6{Lpr/6dU:YC~2!8vo?yY`k\jW\D[u*?opFoc, 9 ,N^;@_? Generally, two voltages are specified for a gearmotor, for example 230 V / 400 V. The lower voltage, 230 V, specifies that one phase of the installed motor (one motor winding) has a maximum load of 230 V. 400 V is the maximum voltage that the motors outer conductor can handle. According to the gear shape, they can be divided into cylindrical gears.

The nameplate-defined parameters for the motor - such as power factor, efficiency, torque and current - are at rated voltage and frequency. (The following data is mainly marked on the nameplate of the AC asynchronous motor and its meaning is explained as follows:(1) Rated power (P): is the output power on the motor shaft. 
That makes them an essential heavy-duty drive that is especially suited for production and logistics. $399.99 + $32.83 shipping. %PDF-1.6

The connection should be consistent with the connection specified on the motor nameplate to ensure compatibility with the rated voltage.Current: The three-phase line current of the stator winding at the rated voltage and rated frequency of the motor and the rated power.Frequency: refers to the frequency of the AC power supply connected to the motor. Depending on the level of gear unit graduation, they can achieve high torques of up to 50,000 Nm.
