Brushless DC Motors

High efficency motors BLDC Motor with longer life span

BLDC motors are pirmarily used in servo applications that require high efficiency, high reliability, and good torque density.

Electrical

Medical devices

Packaging equipment

Robot Joining

The BLDC motor has magnets alleged to the armature and the armature windings  or current-carrying conductors are fixed on the stator. These windings convert electrical energy into mechanical energy by using electrical commutation. 

Apart from the absence of brush, a key difference between the brushless motors and brushed motors is that BLDC motors have an electric switch circuit instead of a mechanical commutator.

Common applications for BLDC servo motors include robot joints, medical devices, and packaging equipment.
