Synchronous vs Induction Motors: A Comparison Guide

To compare synchronous and induction motors, one must understand some key characteristics that describe their performance and behavior. These include the rotational speed of the motor, measured in revolutions per minute (RPM). Synchronous motors have a fixed speed that depends on the supply frequency and the number of poles, while induction motors have a variable speed that depends on the slip. The rotational force of the motor is measured in newton-meters (Nm) or pound-feet (lb-ft), with synchronous motors having a constant torque that is independent of the load, and induction motors having a variable torque that depends on the load and the slip. The mechanical output of the motor is measured in watts (W) or horsepower (HP), with synchronous motors having a constant power that is proportional to the torque and the speed, and induction motors having a variable power that is proportional to the torque and the square of the speed. Lastly, power factor is the ratio of real power to apparent power, which indicates how efficiently the motor uses electrical energy. Synchronous motors have a high power factor that can be adjusted by changing excitation current, while induction motors have a low power factor that decreases with load and slip.

Electric motors play a vital and ubiquitous role in the invisible infrastructure that powers our modern lives. Whether in the gentle sound of a ceiling fan or the deafening roar of sophisticated industrial machinery, these ingenious devices are the silent artisans of our daily lives.

However, the diversity of their functions remains a mystery to many and it can be difficult to distinguish between different types of electric motors. The aim of this article is to lift the veil on this complexity by considering two fundamental categories : synchronous and asynchronous motors. These two protagonists of electrical engineering have different roles and applications, providing specific services adapted to specific situations.

Asynchronous motor

Asynchronous motors connected to frequency converters are the most commonly used type of motor in applications where the speed and movement of a load must be controlled.

Motor drive systems are ideal for applications such as elevators, as they require excellent precision, both in terms of speed (ease of use) and accuracy of car position in relation to stops.

The popularity of asynchronous motors is based on their low maintenance, simple construction, standardization and robustness.

The operating principle of asynchronous motors is based on:

• On the one hand, it is based on the generation of electric current induced in a conductor located in a rotating magnetic field. The conductor in question is one of the squirrel cage rotor rods underneath that forms the motor rotor. Current induction only occurs when the conductors are shorted (because the two side rings connect all the bars).

• On the one hand, it involves the generation of a driving force on the conductor considered (carried by an electric current and placed in a rotating or fluctuating magnetic field), the meaning of which is given by the following rules: Three fingers on the right hand.
