Dc Motor Nameplate

Buy the items featured in this video at 800-337-1720 or visit. AMPSThe amperes shown on the motor nameplate are the full-load amperes drawn by the motor at the voltages given.

DC Motor Ratings The nameplate of a DC motor provides important information necessary for correctly applying a DC motor with a DC drive.

Dc motor nameplate. 1695 amps is the full-load current for this motor. Provide smooth operation at low speeds. First consider a motor with a nameplate marked 115230 volts and 6231 amps.

A downside is a hot motor with a shorter expected life. It was hiding in the DC motors nameplate all the time. The nameplate for a two-pole 15 kW motor may have the following important data.

For example a motor with a 10 service factor cannot be expected to handle more than its nameplate hp on a continuous basis. Armature amps of course will be low since they have little to do with speed. A 10 hp motor could run at 115hp.

Shunt Wound and Permanent Magnet DC. Now just run the motor on the Dc field weakening control drive of your choice up to 1400rpm with a solid 200amps dc on the field winding. The drive shaft bearing is located close to where the drive shaft extends out of the motor.

This is accomplished by connecting coils in series for high voltage or in parallel for low voltage. There may be two bearing specifications on a motor nameplate the drive shaft bearing and the opposite drive shaft bearing. On the nameplate you can see this sample motor is designed to be used on 460 VAC systems.

Base speed is where the motor. Motor nameplate fully explained - मटर क नमपलट पढन सख - motor name plate data details - Electrical DostI am Aayush Sharma Welcome to Our. The nameplate is saying that when the motor is operating at 115 volts and at full-load the motor.

Some manufacturers show several different voltages on the nameplate such as the common 208-230 460 rating. A motor with a 115 service factor can be expected to safely handle infrequent loads to 15 past its rated horsepower. The motor is able to supply a shaft output of at least 15 kW if connected to the mains supply as indicated.

You should then be able to measure about 440vdc on the armature confirming nameplate data. The difference between these two is the location in the motor. In this example we use the nameplate of a W22 Premium three phase electric induction motor manufactured by WEG.

The nameplate FLA is a very important rating that is used to select the correct wire size motor starter and overload protection devices necessary to serve and protect the motor. The rated output of the motor is 15 kW ie. Efficiency and winding life may also decrease evein if the the motor has been derated.

Manufacturers Type and Frame Designation Horsepower at Base Speed Maximum Ambient Temperature Insulation Class. Brushless dc motor in a computer floppy disc drive. The nameplate should identify the motor as dc and indicate the winding type.

A three-phase motor nameplate always specifies the rated line-to-line voltage. Understanding Motor Nameplate Information NEMA vs IEC Standards Course Content. Full motor nameplate details a photo is fine.

Shunt series compound or stabilized shunt. Some motors are designed to operate at more than one voltage. The following specifications are generally indicated on the nameplate.

The stator windings are axial and the rotor is positioned outside the stator. Your motor nameplate may include bearing information. A nameplate contains a large amount of useful information relating to the motor including the type RPM.

We have developed a robust calculation that determines the DC motors efficiency. High starting and breakdown torque. All we need from the existing DC motor application is.

Check out this video for a close look at motor nameplates for Galco TV. This motor for example is rated 230460 meaning it can be wired for operation at either voltage. The motor has three phases and is for a mains supply with a frequency of 50 Hz.

They just make torque. 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.

Other applications of the externally-commutated motor include electric vehicles and other more powerful equipment. Voltage on motor nameplate 2. Revolutions Per Minute RPM The nameplate includes the based speed given in RPM.

Note that the NEC does not require motors this small to have nameplates. NOTE A motors operating temperature at full load may be higher on unbalanced voltage than on balanced voltage. Shunt motors have field windings that are parallel to the armature.

In series motors the fields are in sequence with the armature. For a multispeed motor the full-load current is only listed for the maximum speed. Used on constant or diminishing torque applications with Type K rectified DC power.

Frame size and power of the motor.
