Additional FeaturesPowerful cooler ventilator applied, provides 240m3/h air on commutator side. Allows higher amp load on motor.
Nice homemade platform for switches.
This is an upgrade for the first Romet.
However I managed to increase the nominal power of the motor, the brushes are eated up every 1000 km.
That means its only good for EV races so I will switch motor.
