DC Motor Precious Metal Brush

DC Motor Precious Metal Brush

The combination of our precious metal brush and commutator can ensure high stability and lowcontact resistance, even after long-term parking. The starting voltage and electromagnetic interference of the motor are very small.

Usually used for

- Low loss and high efficiency, the hollow cup rotor is light in weight, small in inertia, and has a sensitive start and stop response speed;

- Large output torque, the hollow cup rotor is made of enameled wire wound, shaped and cured.

There is no rotor core to support these windings. Under the same outer diameter, the outer diameter of the hollow cup motor rotor is larger, and the output torque is also higher.

- Energy-saving characteristics: the rotor energy conversion efficiency of the core cup motor is higher, and the maximum rate is generally above 70%, and some even can reach above 90%.

- Drag characteristics: small speed fluctuation, good running stability, 1/3-1/2 weight reduction compared with iron core motors of the same power.
