Name Plate Motor 1 Phase

Figure 1 typical induction motor nameplate information.

Name plate motor 1 phase. Totally enclosed fan cooled motors with a 1 15 service factor are also widely available and values of 1 25 1 4 and higher exist. It will only develop 2 3 of the 3 φ power rating because one winding is not used. If nothing is indicated on the motor name plate the motor is designed for duty cycle s1. A 1 15 service factor motor can be operated at 15 higher than the motor s nameplate power.

Name plate motor adalah data teknis mengenai informasi umum dari sebuah motor listrik seperti tegangan jumlah phasa frequensi arus nominal daya motor dan sebagainya. The important information that we can see on motor nameplate is a electrical input from this we can know what the voltage for motor the suitable frequency full load ampere type of connection star or delta power factor and others. In many cases the motor can do it continuously which is indicated by an s1 or cont on the nameplate. This name plate shows a frame size 326t.

Does the section of a motor name plate thst says weight. The nameplate for a two pole 15 kw motor may have the following important data. It may be hand started in either direction coming up to speed in a few seconds. Rpm speed the rpm listed on the nameplate is the shaft speed for the motor.

3 φ motor runs from 1 φ power but does not start. However it will not self start. Unless you have a unique application your motor will be rated for single phase or three phase input power. This parameter defines the length of time during which the motor can carry its nameplate rating safely.

Manufacturer s type and frame designation nema defines standard frame sizes. At nameplate voltage and frequency the allowable overload for a motor with a nameplate service factor equals the rated load multiplied by that service factor. The frame size provides a standard for details such as the location of mounting holes a height of the shaft above the mounting plate etc. The 3 beside phase on the nameplate in figure 1 indicates that this is a 3 phase ac motor the motor operates on 3 phase ac power.

The motor has three phases and is for a mains supply with a frequency of 50 hz. Most industrial ac induction motors are rated 3 phase which means that the ac power supply is three separate yet interconnected single phase ac lines with the voltages across the respective windings 120 out of phase with each other. Single coil of a single phase motor. The rated output of the motor is 15 kw i e.

A three phase motor may be run from a single phase power source. We can collected the data for induction motor from name plate this information is very important to troubleshooting or.
