DC motors can be divided into two categories: brushed DC motors and brushless DC motors. Brushed DC motors operate based on the mechanical linkage between their commutator and brushes. Brushless DC motors, however, do not have a commutator and brushes. Instead, they are electronically controlled with a drive circuit. There are several advantages to using a brushed DC motor:
EMS stocks a variety of high torque DC motors, including brushed DC motors, from several leading manufacturers.
EMS is the sole UK and Ireland supplier of FAULHABER motors. The key difference between FAULHABER DC micromotors and conventional brushed DC motors is in the rotor. The special winding used in the System FAULHABER technology does not have an iron core, but instead consists of a self-supporting skew-wound copper coil. The feather weight rotor has an extremely low moment of inertia and rotates without cogging, resulting in outstanding dynamics across the entire range.
For low power motors, it’s best to select commutation systems using precious metals because of their extremely low contact resistance. A copper commutator and copper graphite brushes, however, are recommended for higher power motors to ensure long life even under extreme load conditions.
Available with over a million possible combinations, the FAULHABER ranges of System Faulhaber DC motors, gearheads, encoders, tachos and brushless DC motors offer one of the widest choices on the market. Sizes start from the incredibly small 3mm diameter motor and planetary gearhead, up to 44mm and 200+ Watts, making them suitable for applications such as medical devices, aerospace, control and instrumentation.
