DC motors produce torque through the interaction between the magnetic field generated by the electromagnets in the stator and the magnetic field of the permanent magnets in the rotor. When current flows through the coils, it creates a magnetic field that interacts with the rotor's field, creating a force that rotates the rotor and produces torque.

What are the advantages of using a high power DC brushless motor in industrial applications?
High power DC brushless motors offer several advantages in industrial applications. They are more efficient, have a longer lifespan, require less maintenance, and provide precise control over speed and torque. Additionally, they produce less noise and are more environmentally friendly compared to traditional motors.
How is torque produced in a dc motor?
Torque in a DC motor is produced by the interaction between the magnetic fields created by the stator (fixed part) and the rotor (rotating part). As electric current flows through the coils in the stator, it creates a magnetic field that interacts with the permanent magnets or electromagnets in the rotor, causing it to rotate and produce mechanical torque.
What is the maximum amount of torque, measured in Nm, that this engine can produce?
The maximum torque that this engine can produce is 350 Nm.
What is the maximum torque in Newton meters that this engine can produce?
The maximum torque that this engine can produce is 350 Newton meters.
A torque acting on an object tends to produce what?
A torque acting on an object tends to produce rotation.
Why ac motors are not used in railways?
Ac motor has a low starting torque so that DC series motor used in railways cause DC motor has high starting torque
In what sense dc motor is better than ac motor?
DC motors can spin at a much faster speed and have higher starting torque.
Why DC motors and DC generators are commonly known as DC machines?
because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
Is torque and current proportional?
Sometimes, for example in a separately excited dc motor. But in a series-wound dc motor the torque is proportional to current-squared, which gives the motor a very high starting torque and this makes series motors very popular for traction.
Type of motor used by electric train?
dc series motors are used because of torque vs speed characteristics.
Why will a dc motor produce v but not an ac motor?
Motors do not produce voltage, current, or power. They use them.they produce mechanical output.
What is the best type of DC motor for use with DC?
Basically anything that works with batteries usually works with DC motors, i.g. your hard drive, your cellphone vibrator, toys, etc. Also, even for large motors, the DC motor has the advantage of being easily controlled by input voltage. Induction motors, on the other hand, can use controlled input voltage but they will have to deal wth low torque when the voltage is low. DC motors are used for those little fans in your computer. Also, CD players also use DC motors to spin the discs. DC motors are important where absolute speed control and feedback are necessary. For your household appliances, including fan motors, those are AC motors, cheaper for the industrial strength and more efficient.

Are DVD DC motors and DC motors same?
actually dc motors are of several types in which one of them are 1).brushed 2).brushless ...so the motor present in DVD are the brushless dc motors ...
Advantages of dc shunt motor?
it maintains a constant speed under varing load
Is current proportional to torque?
Yes, current is generally proportional to torque in electric motors. The torque produced by a motor is directly related to the current flowing through its windings, as described by the motor's torque equation. This relationship holds true in many types of motors, such as DC and stepper motors, where an increase in current typically results in an increase in torque output, assuming other factors remain constant. However, the specific proportionality can vary based on the motor design and operational conditions.
Why starter used in DC motors?
starter is used in dc motor to reduce the initial starting torque...so that the dc machine could be protected from damage.... ..and to avoid max ..current flowing ..from it it can damage whole ..moter structure
