Kostov 9" 144V Series Wound DC Motor

Kostov 9" 144V Series Wound DC Motor.  Single Shaft.

The motors are designed with an EV conversion in mind.
They have the following features:
-optimised rpm so they are as close as possible to the typical for an internal combustion engine.
-larger collectors with strengthening rings inside to minimise the possibility of lifting lamellas.
-class H insulation throughout the motors.
-interpoles to minimise brush arcing allowing higher voltages and reducing thermal stress for the collector
-heavy duty SKF bearings
As options can be ordered:
-thermistor for real time monitoring of stator windings' temperature
-sensor bearings to measure rpm (only for the 9" models)
-stainless steel brush springs
-stainless steel shaft
-dual shaft
