What Are Dc Motors Used For Today?


This makes DC motors a good choice for driving constant-torque loads – such as conveyor belts, elevators, cranes, ski lifts, extruders and mixers. These applications are often stopped when fully loaded, and the full torque of the DC motor at zero speed gets them moving again without the need for oversizing.

What are the parts of DC motor?

DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.


What is DC motor Class 10?

D.C. motor can be defined as a machine which converts electrical energy to mechanical energy of rotation based on the principle of magnetic effect of current. The DC motor works according to Fleming's right hand rule.

What is stable and unstable system in DSP?

A system is called a stable system in case a finite change in the input causes a finite change in the output. Examples of unstable systems: a ball on top of an sphere. In theory you can put the small ball on the top of the sphere such that its center gravity is right above the center of the sphere.


Why solids are rigid and hard?

Solids have a definite volume & shape. They are rigid & lack the ability to flow. This is because the molecules in the solid are very closely packed therefore the intermolecular force among them will be much higher than liquid and gas.


What is RNA in biochemistry?

Ribonucleic acid (RNA) is a molecule that is present in the majority of living organisms and viruses. It is made up of nucleotides, which are ribose sugars attached to nitrogenous bases and phosphate groups. The nitrogenous bases include adenine, guanine, uracil, and cytosine.

What is meant by tensile strength class 11?

Tensile Strength: It is the resistance of a material to breaking under tension. So if any object or a body has high tensile strength, which means that body can resist a lot of tension before it breaks.


How do you write a negative feedback example?

Here are a few examples of negative feedback in the workplace:

  1. “You interrupted your teammate during yesterday's presentation and I lost my train of thought. Don't you think you could've waited for your teammate to finish speaking first?”
  2. “You have been arriving late to work throughout the week.


What are the concepts of vectors?

A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of the vector is from its tail to its head.


What is a constructor when is it invoked?

Answer. A constructor is a member method that is written with the same name as the class name and is used to initialize the data members or instance variables. A constructor does not have a return type. It is invoked at the time of creating any object of the class.


What is an objective answer?

Objective, which require students to select the correct response from several alternatives or to supply a word or short phrase to answer a question or complete a statement. Examples: multiple choice, true-false, matching, completion.


What is synapse class7?

Synapse is defined as the point of contact between the terminal branches of axon of one neuron with the dendrite of another neuron. Synapse is a structure in a nervous system.


What is heat 5th grade?

Heat is the energy that transfers from one object to another because of the temperature difference between them. Ex. Conduction occurs when energy is passed from one item to another by touching the two objects. Convection is the movement of gases or liquids from a cooler spot to a warmer spot.


Why is SCARA robot attractive in industry?
