A BLDC motor is brushless, where the commutation is done electronically. There is no need for brushes, as the torque is a function of the electronic action of the brushless motor on the commutator. This means that a brushless motor has fewer parts that can wear out, and there is never any need to be concerned about the condition of the brushes. A BLDC motor is longer lasting and more reliable than their brushed counterparts. It is a very effective motor with an optimized electromagnetic design for noise, vibration and jitter, built for the long-term.

The fluid dynamic bearing designed into this motor was originally developed to satisfy the ultra-precise mechanical requirements and expected long working life of the hard disk drive market. Now, used in our 3-phase brushless DC motor, this same bearing eliminates the limited precision of a ball bearing, minimizing the non-repeatable run out, lowering acoustic noise level and improving reliability. This hydrodynamic bearing system is the right choice for your high precision applications.
