What information is on a motor nameplate?
What information is on a motor nameplate?
The nameplate-defined parameters for the motor – such as power factor, efficiency, torque and current – are at rated voltage and frequency. When the motor is used at other voltages than the voltage indicated on the nameplate, its performance will be affected.
How do you read a nameplate on a pump motor?
The RPM listed on the nameplate is the shaft speed for the motor. The speed of the motor is directly related to the frequency of the line voltage and the number of poles in the motor. At 60 Hz, a 4 pole motor will rotate at approximately 1800 RPM (7200/4 poles).
What specifications must a motor nameplate list according to NEMA?
Understanding motor’s nameplate
- Voltage.
- Frequency.
- Phase.
- Current.
- Type.
- Power factor.
- kW or Horsepower.
- Full-load speed.
What is SFA on motor nameplate?
Service Factor Amps, or S.F.A., represents the amount of current the motor will draw when running at the full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts. Continually exceeding the S.F.A. shown on the nameplate can shorten motor life.
How can you tell if a motor is VFD?
Three major factors should be considered when determining if a motor is compatible with a VFD: the motor winding insulation, motor bearings and pump operating speed range.
What is SF on motor nameplate?
While you may be familiar with the term Service Factor or S.F., there are a couple of important designations found on a motor nameplate that may need more clarification. Service Factor is defined as a motor’s ability to operate under a short-term load. The higher a motor’s S.F. rating is, the more durable the motor.
Which power is mentioned on a nameplate of a motor Mcq?
8. 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 part will surely tell that given motor?
Commutator will surely tell that given motor is DC motor and not an AC type.
What does the nameplate of a motor mean?
All motors have a permanent nameplate which lists all important data, further data is usually available in the motor catalogue. The nameplate for a two-pole 15 kW motor may have the following important data: The motor has three phases and is for a mains supply with a frequency of 50 Hz.
What does the nameplate for a two-pole 15 kW motor mean?
The nameplate for a two-pole 15 kW motor may have the following important data: The motor has three phases and is for a mains supply with a frequency of 50 Hz. The rated output of the motor is 15 kW, i.e. the motor is able to supply a shaft output of at least 15 kW if connected to the mains supply as indicated.
What do the numbers on a motor mean?
Additional Nameplate Information Catalog Number – if blank, the motor is custom. May have unique OEM part or modification # also. CC – Certified Compliant # This number appears on all motors that require compliance with US energy law. DE – Drive End (output shaft end) Spec Number – VERY IMPORTANT This number will provide bill of
What types of motors do we cover?
We cover the complete range of industrial motors – synchronous as well as asynchronous: from standard electric motors through servomotors for motion control applications up to high voltage and DC motors. This is all based on more than 150 years of experience.
