Cutaway view of a brushless DC motor - ResearchGate
Most of the Brushless DC (BLDC) motors drives take up proportional integral (PI) controller and pulse width modulation (PWM) scheme for speed control. BLDC motor drive has strong saturation...
Comparing Slotted vs Slotless Brushless DC Motors - Haydon …
PITTMAN slotless brushless DC motors feature an offering of standard platform designs that can be customized to meet specific performance and application requirements. As examples, spur gearheads can be integrated on motors for an application’s specific torque and cost requirements while planetary gearheads offer a higher speed
Introduction to Brushless DC (EC) Motor and Gearmotor …
Brushless DC motors combine characteristics of both DC and AC motors. They are similar to AC motors in that a moving magnetic field causes rotor movement or rotation. They are similar to DC motors since they have linear speed-torque performance characteristics.

See Figure 1 for a cutaway view of a slotless brushless DC motor. In traditional slotted brushless motors, the stator features a group of flat electrical steel laminations, typically on the order of 0.5mm thick each, which are assembled to form a solid stack.
The "no-cog" motor - Machine Design
2006年5月11日 · Brushless dc motors without wire windings rotate smoothly with practically no cogging or torque ripple. Edited by Robert Repas. This ThinGap motor uses a slotless BLDC design that...
Brushless DC Motors. The mechanical switching of current associated with brush motors is replaced with electronic switching in brushless motors. Brushless DC motors are not simply AC motors powered by an inverter, instead these devices use rotor feedback devices so that the input wave forms are kept in proper timing with the rotor position ...
DC Motors: Intro to Servos, BLDC motors, Steppers & More | Circuit
Brushless DC motors (a.k.a. BLDC motors or BLDCMs) are one of the newer kids on the block as far as motors go. As their name implies, they have no brushes. This makes them more efficient — brushes making contact with the commutator causes friction losses.
