DC motors & BLDC motors
The DC motors cover the power range of 0.06 to 1,670 Watts and include both “brush” and “brushless” (BLDC) types.
The brush types include both “ironcore rotor” and “ironless rotor” DC motors. The “ironless” motors are usually referred to as “Micromotors”.
Micromotors are especially useful in applications requiring linear characteristics, maximum efficiency, and small space.
BLDC motors are particularly known for long life as there are no brushes and commutators to wear out since the motor commutation is done electronically and usually contain Hall sensors to determine commutation timing.
