A motor is an electrically powered device that converts mechanical energy. Motors come in a variety of shapes and sizes.
DC MOTOR :
The motor is very popular. The starting costs are often lower per unit than ac systems, but faster speeds can be managed by altering the power supply voltage.
- Over a wide variety of speeds, you can control them.
- Quick acceleration, stopping, reversing, and starting.
- High Torque at Start-Up
- The speed-torque curve is linear.
- Installation is simple.
BRUSHLESS MOTOR:
However, you may be wondering what a brushless motor is.
It is simply referred to as a BLDC motor, which stands for brushless dc motor. It has a high efficiency and controllability, and it is widely employed in a variety of applications.
In comparison to other motor types, it saves energy.

APPLICATION:
-
Fans.
- Vacuum cleaners
- Machines for washing clothes.
- Other consumer electronics, such as air conditioners
BRUSHED:
- It is a classic motor.
- These motors are utilised in industrial equipment and can be divided down into the following categories:
- Permanent magnets are employed in servo systems and robotics where accurate low torque and control are required.
- Because it has a high beginning torque, it is employed in autos, hoists, lifts, and cranes.
- Lathes, vacuum cleaners, conveyors, and grinders are all examples of Shunt Wound applications.
- Compound Wound Compressors, circular saws, variable-head centrifugal pumps, rotary presses, shearing machines, elevators, and continuous conveyors are all driven by compound wound.
AC MOTOR :
This motor is more flexible than DC motors, with speed control (vsd- variable speed drives) and a significantly bigger installed base.
Advantage :
-
Torque restriction that can be adjusted
- Low usage of electricity
- Acceleration that can be controlled
- Operational speed can be changed
- Starting current that can be controlled
- Disturbances on electricity lines are reduced.
Types Of AC Motor Include :
Asynchronous:
- It uses electromagnetic induction from the stator winding’s magnetic field to generate an electric current in the rotor, and therefore torque.
- These are the most prevalent form of AC motor and are significant in industry because of their load capacity. 1-Phase induction motors are used mostly for low loads, such as in household appliances, whereas 3-Phase induction motors are utilised more in industrial applications.

APPLICATION:
- Compressor.
- Pumps.
- Conveyor systems and
- Lifting gear.
Synchronous:
Induction and synchronous motors are the two most prevalent types of three-phase motors. An electrical field is created when three-phase electric conductors are positioned in specific geometrical configurations.
APPLICATION:
- Robots
- Instrumentation
- Machine
- Process control
Servo Motor :
- It employs both rotary and linear actuators.
- It is utilised in situations that require a lot of power.
- It is the robotics’ backbone.
APPLICATION:
- Elevators.
- Rudders.
- Walking a robot.
Stepper Motor :
- It has an internal rotor that is controlled by an external magnet.
- Permanent magnets or a soft metal can be used to make it.
- It is used to advance from one location to another in predetermined intervals.
APPLICATION:
- Hard disk drives.
- Robotics.
- Antennas.
- Telescopes.
- and some toy.
