Whether you are looking for a new HVAC, want to optimize the performance of the current one, or carry out some repairs, the first step is to understand how they work.

One of the notable things about induction motors is the harmonic effect. Harmonic is a voltage at a multiple of the primary frequency of the motor system, generated by induction of non-linear loads like discharge lighting or saturated magnetic devices. In most electric motors, harmonic effect results in heating, noise, and harmonic current in the rotor. However, DC motors are better because they do not create any harmonics and you can operate without worrying about associated problems.
