The force in permanent magnets is conservative - so no work is done over a cycle. As a result, the motor would stop moving after a short time and return to the equilibrium position. Therefore, according to the rules of physics, a magnetic motor that independently generates free energy cannot exist.

The OMPM series permanent magnet motors, designed and built by OME Motors, are the best model for efficiency, power and size among those permanent magnet motors available on the market.

Neodymium magnets are often used in motors and are best known for their high strength-to-weight ratio, making them ideal to use in compact motors. Ferrite magnets are more cost-effective making them popular for low-cost motors due to their low manufacturing cost.

According to applicable laws of physics, a magnet motor can not run without external energy input. The same reason also makes it impossible for such a magnetic motor to generate energy autonomously. This YouTube video-link clearly explains the facts and demonstrates why magnet motors can not generate free energy.
