The nameplate includes the based speed given in RPM. Base speed is where the motor develops rated horsepower at rated voltage and frequency. Base speed indicates how fast a fully-loaded output shaft will turn the connected equipment when proper voltage and frequency is applied.
Which power is mentioned on a nameplate of a motor?
Which power is mentioned on a name plate of a motor? Explanation: Name plate of the motor shows rated values i.e. rated speed, rated current, rated voltage. It also shows output power available at shaft when all other quantities are set to rated values.
Which of the following information is available on the name plate of a motor?
The NEC states that the motor nameplate must show the following information: Rated voltage or voltages. Rated full-load amps for each voltage level. Frequency.
Which DC motor has maximum self loading property?
Which DC motor has got maximum self-loading property? Explanation: A differentially compound DC motor, flux reduces so sharply at small increase in load at higher values of load.
Which motor has highest no load speed?
Explanation: At no load, armature current tends to zero, flux φ tends to zero, where speed is inversely proportional to the flux, speed will tend to infinity. Thus, no load speed of DC series motor is highest.
What is the importance of name plate of motor?
Much of the information you need to identify an electric motor is contained on the motor’s nameplate. The nameplate also provides some basic information about a motor’s operating characteristics. Proper motor selection is extremely important for safe, efficient, and reliable motor operation.
How do you know if a motor is inverter duty?
Motor insulation systems that are rated for inverter use will be specified on the motor nameplate (or a sticker). These systems should have wire rated for a minimum of 1600 volt spikes, F or H class insulation, and will be processed with 100% sold resin in a vacuum pressure impregnation (VPI) system.
What is motor rated power?
Rated power is the power which a machine or device can deliver under design voltage and frequency conditions. In an electrical machine or motor , this means the physical power which can be delivered under these conditions.
What is the T rating on a motor?
The higher the kV rating the faster the R.P.M of the motor. The lower the turns, the higher the R.P.M. of the motor. 3.5T means 10,500 RPM. 4.5T means 9,000 RPM.
