What is listed on a motor nameplate?

What is listed on a motor nameplate?

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.

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.

How do you read A motor code?

The higher the letter in the alphabet , the higher the safe operating temperature, and the longer the winding will last at any given operating temperature. Reducing slip rpm increases motor efficiency, so more efficient designs usually have higher full-load speeds.

What is IA in motor?

IA/IN ratio is the ratio of starting current to rated current of Ex e motor and it should not be more than 10 [2]. The higher value of tE of rotor and stator indicates good quality of insulation system design.

What is a motor ID?

Motor identification is a feature of InstaSPIN that allows identification of parameters for sensorless control. This feature enables users to run their motor to its highest performance even when motor parameters are unknown.

What is IC in motor nameplate?

Electric motors are designed for different types of cooling. Normally the cooling method is stated in accordance with international standard IEC Publication 34-6. Figure 5 shows the designations of this standard and IC stands for International Cooling.

What is nameplate RPM?

Revolutions Per Minute (RPM) 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.

Where is the motor nameplate on a motor?

We have all seen the motor nameplate attached on the motor side (or on top). All motors have a permanent nameplate which lists all important data, further data is usually available in the motor catalogue.

What do the bearing specifications on a motor nameplate mean?

Your motor nameplate may include bearing information. There may be two bearing specifications on a motor nameplate, the drive shaft bearing and the opposite drive shaft bearing. The difference between these two is the location in the motor.

Do all motors have a permanent nameplate?

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:

What does the enclosure type of a motor mean?

The enclosure type displays information about how well the motor is protected from the environment. The most common enclosure types are Open Drip-Proof (ODP) and Totally Enclosed Fan Cooled (TEFC). ODP – An Open Drip-Proof motor is an open enclosure that allows air to flow freely inside around the windings.
