True or False: One disadvantage of three phase motors is that they do not last long.

The assertion that three-phase motors do not last long is false. In fact, three-phase motors are known for their reliability and durability compared to single-phase motors. They are constructed to run efficiently and typically experience less wear and tear due to their ability to distribute power evenly across the motor windings. This balance reduces overheating and the likelihood of premature failure.

Additionally, the three-phase power supply allows these motors to operate at a more constant torque, minimizing stress during operation. As a result, with proper maintenance and use, three-phase motors generally have a long service life. Factors such as maintenance schedules, environmental conditions, and operating loads have a more significant impact on motor lifespan than their design type. This is why stating that three-phase motors do not last long is inaccurate.
