Which of the following motor is preferred for automatic drives?

Ward Leonard method of speed control is used for controlling the speed of a DC motor. It is a basic armature control method. It is preferred for automatic drives.

Which of the following motor is preferred for traction work?

Explanation: DC motors are used for traction as, according to the characteristics of DC motors speed is inversely proportional to torque and square of armature current as well, if linear magnetization is concerned. Thus, DC motors are perfectly suitable for traction. 2.

What is a blower motor?

The blower motor is the fan that pushes heated or cooled air through dashboard vents based on the climate system settings and the fan speed selected. … Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood.

What is a fan motor?

Fan motors are very simple in construction. They consist of a synchronous or asynchronous electric motor, with a fan wheel of the associated shaft, and the connections for the lines. … All motors consist of a stator and contain a rotating rotor inside, which is surrounded by pole-pieces.

Which type of DC motor is used in blowers and fan?

Generally, there are two types of DC ceiling fans: brushed DC fans and brushless DC fans. Brushed DC Fan: A brushed DC fan used DC motor with brushes. A simple brush DC motor consists of a rotor, a commutator, an axle, brushes, and a permanent magnet.

Which motor is used in fan AC or DC?

Most ceiling fans, as well as most household appliances, use AC motors, as AC is the type of current distributed by power companies. AC motors function by being connected directly to a power source.

Which motor is usually preferred for the elevator nowadays?

AC slip ring or DC compound motors are prefer for lifts. Shunt type commutator motors are preferred in case of single phase installation. The latest lift designs use 3-phase induction motors with variable frequency drive electronic controls.

Which DC motor is preferred for elevator?

DC cumulative compound motor having high starting torque up to 450% depending upon the degree of compounding. The speed regulation is varying up to 25 ~ 30%. That’s why these motors are used in elevators.

Where are reciprocating compressors used?

Reciprocating compressors have many uses in industry, including natural gas processing and delivery, chemical plants, and oil refineries. Compressed gases also play a major role in refrigeration technology, where the subsequent re-expansion of the gas after compression produces the required cooling effect.

Which of the following is a type of a reciprocating compressor?

There are two types of reciprocating compressors: High speed (separable) Low speed (integral)

Which type of motor is used in compressor?

The most common electric motor is a three-phase squirrel cage induction motor. This type of motor is used in all types of industries. It is silent and reliable, and is therefore a part of most systems, including compressors.
