cl series coreless dc motors

The Premotec Coreless DC motors have a maximized performance due to the use of precious metal commutation in combination with high performance magnets. As these motors are coreless there are no iron losses, no preferred rotor position and due to the use of many phases, the torque ripple is reduced to a minimum.


The CL series motor performance is summarized below.
