Difference between DC Motor and AC Motor

An electromechanical device that converts electrical energy into mechanical energy. An AC motor is an electromechanical device that runs on AC electricity while a DC motor runs on DC electricity.

More about AC motor

An AC motor consists of two main parts: a rotor, a rotating component, and a stationary stator part. Both have coil coils to create a magnetic field and magnetic field repulsion creates the rotor to move. The current is delivered to the rotor through slip rings, or using permanent magnets. The kinetic energy of the rotor delivered to the shaft connected to the rotor and the torque generated act as the driving force of the machine.

There are two main types of AC motors. Induction motor, which runs slower than the source frequency, is the first type. Synchronous motor is designed to avoid the effect of induction; So it operates at the same frequency or a sub-multiple of the frequency.

AC motors can produce large torque. Because of the power source used, it can be designed to draw large amounts of power. Power mains can provide the very large currents required to run heavy-duty motors. Most common AC motors use a squirrel cage rotor, which is found in nearly all household and light industrial AC motors. Most household appliances such as washing machine, dishwasher, stand-alone fan, record player, etc. use a different type of squirrel cage rotor.

AC motors are designed for three-phase and two-phase single-phase power sources. Depending on the requirements, the use of the type of motor varies.

More about DC motor

Two types of DC motors are in use; They are the brushed DC electric motor and the brushless DC electric motor. The basic physical principle behind the operation of DC and AC motors is the same.

In brushed motors, brushes are used to maintain electrical contact with the rotor coil, and the internal switching changes the polarization of the electromagnet to keep the rotational motion going. In DC motors, permanent or electric magnets are used as stationary elements. In a practical DC motor, the motor coil consists of a number of coils in slots, each extending for 1/p of the rotor region of the p-poles. Small motors may have up to six coils, and may be up to 300 on large motors. All coils are connected in series, and each junction is connected to a reflective tape. All coils under the shafts contribute to the torque production.
