The AC Motor and the DC Motor are differentiated on the various factors like the source or the nature of the power used in the motor. The commutation process, types, starting of the motor, a number of terminals.

While both A. C wound field motors are constructed with brushes and a commutator, which add to the maintenance, limit the speed and usually reduce the life expectancy of brushed D. The final basic difference is speed control.

What is the difference between an AC motor and a DC motor?

Electric motors play an essential role in almost every industry. Using the right type of motor with high-quality parts and regular servicing keeps your facility running smoothly and prevents damage to the endpoint equipment due to wear or power surges. Gainesville Industrial Electric can help your company select the right industrial electric motors and parts for your applications.

Electric motors are machines that convert electrical energy—from either stored power or a direct electrical connection—into mechanical energy through the production of rotational force. The two major types of electric motors are:.

Both AC and DC motors use electrical current to produce rotating magnetic fields that, in turn, generate rotational mechanical force in the armature—located on the rotor or stator—around the shaft. The various motor designs use this same basic concept to convert electric energy into powerful bursts of force and provide dynamic levels of speed or power.

While electric motors may differ from one design or type to another, many of them contain these parts and assemblies located from the center working outward :. AC and DC motors are broad categories of motors that include smaller subtypes. Induction motors, linear motors, and synchronous motors, for example, are all types of AC motors. Each motor type has different advantages that make them best suited for different commercial and industrial applications. AC motors , for example, are flexible and easy to control.

Some of their other advantages include:. 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. Both AC and DC motors find application in processes and facilities in almost every industry.

Some of the most common industrial applications for AC motors include:. We are also an authorized factory warranty center.

Difference Between AC and DC Motor

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances.


This chapter deals with the basic mechanisms of motor operation, so readers who are which are used with motor drives, providing either d.c. or a.c. outputs.


How a DC motor works?

Together, these worksheets constitute a body of questions far too large to be comprehensively covered in any single electronics course. That is not the point, though. This collection is purposely oversized so you may pick and choose enough questions to meet your specific teaching needs. Download those worksheets containing questions you wish to use, and then only assign those questions to your students for research and discussion.

Theoretically, the same DC machine can be used as a motor or generator. Therefore, construction of a DC motor is same as that of a DC generator. An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: " whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force". Fleming's left hand rule : If we stretch the first finger, second finger and thumb of our left hand to be perpendicular to each other, and the direction of magnetic field is represented by the first finger, direction of the current is represented by the second finger, then the thumb represents direction of the force experienced by the current carrying conductor.
