What is commercial electric motor?
Answer: (c) A commercial electric motor is one which uses the following (i) An electromagnet in place of permanent magnet. (ii) Large number of turns of the conducting wire in the current-carrying coil. (iii) A soft iron core on which the coil is wound. The combination of soft iron core and coil is called an armature.
How are electric motors commercially used?
AC Motors are electro-mechanical devices powered by alternating current to produce rotational motion. The rotation provides mechanical work to drive other rotating machines such as pumps. … AC motors form a large portion of motors in use today and drive pumps, fans, compressors, etc.
What are the special features of commercial electric motor Class 10?
Special features of commercial electric motors are:
- The coil is wound on a soft iron core; therefore, the strength of magnetic field increases.
- The coil contains large number of turns of insulated copper wire.
- A powerful electromagnet is used in place of permanent magnet.
What are the types of motors?

What is difference between electric motor and commercial motor?
In electric motors, the split ring acts as a commutator. … In commercial motor an electromagnet is used in place of permanent magnet. Commercial motors have more number of turns of conducting wire in current carrying coil. Commercial motors have soft iron core on which the coil is wound.
What is the difference between simple motor and commercial motor?
A simple motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on a coil which rotates it continuously while in commercial motors, the coil is bound on a soft iron core which becomes magnetized and increase the length of the magnetic field …
Why are electric motors important?
Electric motors impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and multitudes of other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy.
Which motor is more powerful AC or DC?
AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.
Does Tesla use AC or DC motors?
Tesla, for example, uses alternating current (AC) induction motors in the Model S but uses permanent-magnet direct current (DC) motors in its Model 3. There are upsides to both types of motor, but generally, induction motors are somewhat less efficient than permanent-magnet motors at full load.
What is the special features of commercial electric motors?
In commercial electric motors: The coil is wound on a soft cor. This increases the strength of magnetic field, which makes the motor more powerful. The coil contains a large number of turns of insulated copper wire.
What is electric motor class 10th?
The Electric Motor. An electric motor is used to convert electrical energy into mechanical energy. … Motors convert electric energy to mechanical work. The opposite is done by generators that convert mechanical work to electrical energy.
What are the principles of electric motor?
The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
What are the two types of motors?
