Name Plate Motor 3 Phase

Electric motor name plate there are many types of electric motors some smaller than a human hair others large enough to power a locomotive.

Name plate motor 3 phase. This parameter defines the length of time during which the motor can carry its nameplate rating safely. In the case of the above image the connection will be made in delta because the mains voltage we have is 400v and the wiring of the coils of this motor is with a mains voltage of 400v in delta and with a mains voltage of 690v. The motor has three phases and is for a mains supply with a frequency of 50 hz. Seeing the following nameplates we will connect a three phase ac motor as follows.

Rpm speed the rpm listed on the nameplate is the shaft speed for the motor. The rated output of the motor is 15 kw i e. The nameplate for a two pole 15 kw motor may have the following important data. Untuk motor induksi 3 phasa yang ber name plate 220v 380v ini tidak dapat digunakan pada rangkaian kontaktor hubung star delta.

If nothing is indicated on the nameplate the motor is designed for duty cycle s1. Go back to index reliability 11. We connected the motor to 410v 3 phase system the rpm is1440 the load in the multy meter is 19a we need the name plate details please guide us. Unless you have a unique application your motor will be rated for single phase or three phase input power.

A three phase motor nameplate always specifies the rated line to line voltage. In many cases the motor can do it continuously which is indicated by an s1 or cont on the nameplate. I think it means that the motor should be switched on only under load. This motor for example is rated 230 460 meaning it can be wired for operation at either voltage.

Motor induksi 3 phasa jenis ini menunjukkan kalau motor yang terhubung delta segitiga tegangan suplaynya harus bertegangan 220 volt 3ø dan kalau terhubung star bintang tegangan suplaynya haruslah bertegangan 380 volt 3ø. Nema allows motors to operate at plus or minus 10 of the nameplate voltage rating while pointing out that this may degrade performance or efficiency. Single or three phase. Some common ratings are 200 230 460 and 575 volts.

For the purpose of this page we will be discussing induction motors which are typically found on most workshop machinery such as air compressors drill presses table saws band saws jointers shapers and lathes. The motor is able to supply a shaft output of at least 15 kw if connected to the mains supply as indicated. Nema defines standard voltage rating for three phase motors. A three phase motor has a nameplate that reads duty plugging this means that the motor is what.

The speed of the motor is directly related to the frequency of the line voltage and the number of poles in the motor.
