What are the various specifications of a motor?

Motor specifications

• Nameplate.
• Voltage and amps.
• Horsepower and kilowatts.
• Base speed.
• Service factor.
• Insulation classes.
• Motor design.
• Locked rotor code letters.

What are the specifications for AC motor?

Multi-Speed AC Motors Typical speeds for 60-Hz AC motors are: 3,600/1,800 rpm (2/4 pole) 1,800/900 rpm (4/8 pole) 1,200/600 rpm (6/12 pole)

What are the specifications of DC motor?

Motor Specifications

• Standard 130 Type DC motor.
• Operating Voltage: 4.5V to 9V.
• Recommended/Rated Voltage: 6V.
• Current at No load: 70mA (max)
• No-load Speed: 9000 rpm.
• Loaded current: 250mA (approx)
• Rated Load: 10g*cm.
• Motor Size: 27.5mm x 20mm x 15mm.

What is a specification plate?

Specification plates found on cargo tank trucks provide emergency personnel with a variety of information at a hazardous materials incident involving these tanks. The information stamped on the specification plate identifies the type of cargo tank truck and its characteristics.

What is PG in induction motor?

The power available at the air gap of induction motor is called Air Gap Power. It is denoted as Pg. Air Gap Power is basically the rotor input power. It is the gross power available at rotor input and supplies ohmic loss, friction & windage loss and mechanical power output.

What is the maximum speed of AC motor?

(1) In case of AC motors (induction motors and synchronous motors) running on a fixed frequency supply, maximum speed is the synchronous speed corresponding to two pole machine. Thus, for 50Hz supply voltage, maximum speed is 3000 rpm.

What is the RPM of 12v DC motor?

18000 RPM, 12V DC Motor.

What is RPM of DC motor?

RPM, which stands for revolutions per minute, is the amount of times the shaft of a DC motor completes a full spin cycle per minute. The amount of 360° turns, or revolutions, a motor does in a minute is its RPM value. So a motor with an RPM of 24,000 is much more high speed than a motor which has 2400RPM.

What is a rating plate?

Also known as data plates, placards or nameplates; rating plate labels identify a piece of equipment’s manufacturer, serial/model number, date of manufacture, load rating, electrical specifications, operating/maintenance instructions and other required data.

What are the important ratings mentioned on the nameplate of a three phase induction motor?

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.

What is an induction motor?

Induction machines are the most frequently-used type of motor used in residential, commercial, and industrial settings so far. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding.

What is a 3-phase induction machine?

3-Phase induction machine construction • 3 stator windings (uniformly distributed as in a synchronous generator) • Two types of rotor: –Squirrel cage –Wound rotor (with slip rings) The rotating magnetic field

Do single phase induction motors self-start?

The single-phase induction motor does not self-start. The main winding carries a sporadic current when the motor is attached to a single-phase power supply. It is quite logical that the cheapest, most reduced upkeep sort engine ought to be used most regularly. Based on their way of starting, these machines are categorized differently.

How many stator windings are in an electric motor?

• 3 stator windings (uniformly distributed as in a synchronous generator) • Two types of rotor: –Squirrel cage –Wound rotor (with slip rings) The rotating magnetic field • The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating.
