Construction of BLDC is exactly similar to the a) Conventional DC motor b) Induction motor c) Permanent magnet synchronous motor d) Totally different construction.

Understand the Problem

The question is asking about different types of motors, specifically focusing on the construction similarities between BLDC and other types of motors, as well as the placement of magnetic material in PMDC motors.

More Information

The construction of a Brushless DC (BLDC) motor is similar to that of a Permanent Magnet Synchronous Motor (PMSM). Both use permanent magnets on the rotor and have an electronic means of controlling the motor, making them efficient and reliable.

Tips

A common mistake is confusing BLDC with conventional DC motors due to their name, but BLDC has a construction and operation more like an AC motor.
